Cleanup – Quick Start Guide      This Quick Start Guide is designed to help you getting       started with Uninstall Manager's companion product (part of the       NeatFreak Pack), Cleanup.
! a+ f8 Q: I" E            Overview
# Z# ]! Y1 \, F- k      Cleanup helps you analyze and safely clean your device from       old leftovers, or as some would call it, junk.( {9 d' s. N2 j4 U9 ~4 q* C9 B* i
            Cleanup is using the term "items" to refer to Files and       Preferences.' a' S+ V3 D: ?# s( e! ~* _
      What are these then?
2 W& p+ I  a# p; y$ q; f            Files
1 M+ C0 Y; A3 ]. C5 F6 h! ~      You are probably already familiar with the term Files, or you at least you       should be since files hold all of information you work with on your device.
  t# b' w- n- F2 ?5 V7 p4 X, L( z      Each application you install (or installed, for that matter)       to your device is composed out of files.
5 \6 D- P# |+ I- \+ J, Y      Even the application itself (the       program you can launch and use via its icon) is a file.6 Q# @1 }; i9 f+ W' f% W
      In the Palm OS world (the operating system that takes charge of your       handheld or Smartphone) these files are called "Databases" since they are       built up out of records containing different information.
3 V5 Y; F, K4 V, z$ D! Q: [3 T# Q      Let's say we are talking about a game: The game's level packs or music       could be inside different files than the game itself. In case of an       accounting program; each individual account can be a different file, etc'." _$ w/ ^; `0 f) a) P9 W
            Preferences/ l7 ]( i' r( L) h8 X' H  {
      An application saves little bits of information so that once you close it,       it won't "forget" this information the next time you want to use       it. Applications, in a sense, could use their own files to store this       data, but the Palm OS has a special feature and place which allows       applications to save and retrieve little bits of information fast.      This special place is called Preferences Files.
9 {9 t; u# M: E/ A; B& [8 H. o& p      

        

• There are two files of this sort on a Palm OS based           device: Saved Preferences and Unsaved Preferences.. b# U* ]; V& o: x& B% R* P" r
           
  1 B" E' y1 r/ {. Y% B3 I$ h2 T          For this tutorial we are assuming there is one file to store these           preferences and in real life it doesn't really matter which is which           (as a side note, it really doesn't matter and there should have           been only one file, but for some obscure system design decision, there           are two).

      

            So, where's the problem?
) U1 [( ~, a2 m6 E$ t; N1 q+ p            Ok, this is how it works: When applications save/create new       files and preferences on your device they have to "tag" them with a       special value. This special value is known as the Creator ID. Each       and every application on your device has to have a unique Creator       ID. When the time comes and you want to delete, let's say, a game you       broke all of your records, again and again; you are essentially telling the Palm       OS: "please delete Boring_Game".2 B% |$ q6 [# \$ `# x  D1 T5 \
            Remember the Creator ID? When the Palm OS receives the       command that one of the installed applications is "going down", it knows       which of all files and preferences on your device belong to that       application by looking at the unique application Creator ID and comparing       it to all other items on your device." R+ J7 V& C8 j
      When it finds an item that is tagged with that unique Creator ID, the item gets       the "polite escort out".
3 e( G- A9 o; a! b4 E, D& L' n            Uninvited Guests( U0 X& \/ G, B( ]0 s
            In every party there are always a few uninvited guests, but       for some reason they are the ones who are the hardest to get rid of (not       really, but it's a good assumption for the sake of this tutorial).
4 E8 t, H6 T2 I! [5 l, j      In       the Palm OS world these "guests" are called: unassociated items.
, ~, T' g" f% P) y8 B9 R% F      These items are saved to your device with a Creator ID that does not match       any application on your device.
1 p# L: E  R1 u; t" s. J      When you delete application X that created item Y, and       X's Creator ID is different than Y's Creator IDs; the Palm OS       will ignore Y keeping it on your device       (this frequent "phenomena" happens from all sorts of reasons. This is not       the time nor the place to go into details, let's just say that it happens,       and quite a bit more than it should. click here for more)5 V9 W# w; `5 t8 ]1 O
            Cleanup will help you get rid of these uninvited guests and       will make some more room for...well, for more uninvited guests. But,       the next time these uninvited guests appear, Uninstall Manager will make       sure to "tag" them before they enter the door and kick 'em out when they       are just about ready to leave.
# x( X$ n9 H+ S            So how do you actually work with Cleanup?
/ r0 {) g& G4 x, H/ D4 n- n            When you first launch Cleanup, it will list all items       (files or preferences: depending on the selected view; see the manual for       information on how to switch between views) that do not share a Creator ID       with one of the installed applications.! L; L* U6 ]) K+ s2 t
            Unassociated items, or "uninvited guests" are divided into       two different groups:
- n# B) l1 r- z( d3 w8 l      

• Orphans: Items saved by long-forgotten Trialware         software you once tried and decided to delete.
• Items that are needed on your device that simply do         not have an associated application. These items are not truly "uninvited         guests", but more of part of the security force to keep the other guests from "tearing the         place down".

      As you might expect, you want to get rid of the orphans,       but leave the other ones in place.9 e, X8 l2 l: B

      * The explanation here will focus on the Files view, but it       is exactly the same when it comes down to Preferences.2 q) p0 P: z5 R& E4 h) M
      So how do I know if the file belong to the security       forces (needed) or is an uninvited guest (unneeded)?
& d4 L  B  I4 T      Cleanup has a few tricks up its sleeve that help you determine which are       which.
* q# m( n: p! W& I3 p3 G" N  |/ B% Y      First things first, the "Colour Coding"8 u  \: T! o5 k6 f
      As you can see, the items in the list above follow a      blue     dot,    .
9 d, c& C3 T+ X8 g8 n$ D      What this means is that the items were not       monitored by Uninstall Manager when created or       listed in the Signature File.
' B8 d- L( M" @0 ^9 U$ A- ~7 D       Items monitored by Uninstall Manager   (Green dot,   ).$ n& V7 P; s, y; j  \. z1 q' U
        Items marked with the green   colour were monitored by Uninstall Manager. This means that these      items will be removed from your device when you uninstall (using   Uninstall Manager) the application that created them. In most    cases, you can ignore green     coloured items or add them to the     Safe   List since Uninstall Manager is responsible to delete them   when the time comes., c( j$ f" l7 \% _
        Items listed in the Signature File   (Orange dot,   ).2 R4 ]4 ~; o( f- l
       Items marked with the orange   colour are items listed in the Signature File. When you select one of these items and then select the   Details button, you will see information concerning the       item from the Signature File. Sometimes, it will show that item       belongs to the operating system itself (will be marked "Palm OS", or  "Sony", etc), other times you will see the item belongs to a game you no       longer have. Based on the information found in the Signature File you can   decide whether to delete or keep a certain item.- _/ J) @! c# H; ~
      So, the first thing you should do in order to find out   more about suspicious items is to download and install the latest Signature File.

• The Signature File is a growing collection of known           "hidden" Creator IDs that certain applications use to save their data           and of other system components that are not associated with a single           application (for instance, the Graffiti Library which is needed by all           applications).

      

      For the time being, let's say you haven't installed the       Signature File as of yet.
. z4 a1 n. c! Y# D      For this example, we have selected a file called: "Bad       File" (very suspicious name, indeed) and to find out more, we selected the                        Details button:" q- a. w+ @2 ~! X1 w6 a
                     
; ?0 G. z3 v8 l! Z! u( d8 b      Figure 2 : Details Dialog
: @$ _) N' `: q' m5 U( ~/ |/ T4 g: M      The Details Dialog displays all the information it can       find concerning the selected item: Its Creator ID (the Creator ID that       Cleanup couldn't find any application that shares the same one), the Type       (this is the Palm OS database type attribute which can be ignored if it       doesn't mean a lot to you), the Signature Field which currently shows       "Please install the latest Signature File" and the Monitored field that       shows "N/A" - Not Available (which means that Uninstall Manager was not       there to monitor this file upon creation)
# |; V. F) o+ h+ R      So what can you tell me about this "Bad File" file       then?
. a9 C3 ?  j1 m! n! T2 B      I can tell you that "Bad File" was saved under the       Creator ID: bAdF and has the Type ID of: data.
: |' `# J7 L$ q. U3 I      Well, that's not very helpful now, is it? No, it is definitely does not       help us determine if "Bad File" (despite its very obvious name in this       example) is needed (a system file) or not (a piece of an old game you no       longer have).
) u) [7 l5 i& y! k# i      After installing the Signature File, selecting       "Bad File" and Details again, you might                  see:" U; ?1 `: O3 x' _* S

      After installing the Signature File it's pretty       reasonable to think that the file is not needed and can be safely deleted       (hey, it's spelled: "This file is bad", that's the most obvious the       Signature File is ever going to be).
& R! ]! O3 i3 O: R1 b      Sometimes you will see in this field something similar       to: "Crazy Rocket-Fire-Backgammon" which you might remember installing and       getting rid of after 3 minutes of intensive gaming. In this case you will       also want to delete it since it is not needed on your device anymore (its       parent application, the Crazy Rocket game, has been deleted but for      one reason or another, some of its files were       left behind).
7 `/ `4 Q" c8 ?% n      What if "Bad File" is not listed in the Signature       File and all I see is N/A on the Signature Field?

          You can also sign up for receiving         update notifications to your email.

      For these kind of events, Cleanup's answer is the       Search function:
" \6 ]' K% F& ^/ v      The Search process/function will go over each and every       application on your device (main memory and selected directories on the       expansion card) and will try to see if the item you're looking at belongs       to one of them or not.$ i- }6 \6 B: d0 J6 K/ S' E7 z
      The Search process is by no means foolproof, but it can       help you be more or less certain if the item you're examining is needed or       not.0 X& `; Z0 F7 Z1 m* `
      When you select the Search button, you will see       the following dialog which allows you to set the process' settings and       select directories on the expansion card (directories that contain applications)) C& X$ F) m- C

      Once the process is complete and all of the applications       have been searched (in the main memory and the expansion card) you will       see the following dialog (with different results):

/ e: x7 z" k1 ]) y6 d0 h      To sum up this dialog without drowning in technical       details, it would be suffice to say that the greater the number you see on       the list is, the greater the likelihood that the application that is       listed on the same line as the number, is the one responsible for creating       it (which means that the item is still needed since its parent application       is still installed).: `/ V4 g- `0 d: q0 o9 [!

      By using the information from the Results page, you can       reach a conclusion regarding that item (see the user manual for more);       whether to keep it or to delete it.

$ D, e' U. U$ R$ U# f+ j& E      Everything. That’s right; everything as long as you use the      Backup option and you are making sure that the file is backed-up to       the expansion card.

• Before reading the manual, don't forget to read the         Quick Start Guide.
• You might also want to take a look at the         Basic Definitions section.

      Cleanup lists, examine and lets you       delete items in the RAM that are not associated with any one application on       your device; items that DO NOT share a Creator ID with one of the installed       applications.$ v% c+ e4 m) A" F* f
      Why do I need Cleanup?
& g) E! |( \. p5 X      
1 l3 M- x7 J: k; W2 w0 m            When you launch applications, from the built-in memory or the Expansion       Card, they save data (files and settings) onto your device. This data is used       by the application when active, and normally, will be deleted when you delete       the application itself.
7 `& s5 o/ M- q, Y      0 g5 Q; b3 }7 S$ Z1 _( q
      Each and every application on your device has to have a unique Creator ID       which has to be registered with Palm.+ P: l/ N2 E9 |6 O
      Applications, in general, use their Creator ID to tag the data they save.       When you choose to delete an application via the normal delete function (or       using a 3rd party launcher); the system knows which files and preferences       it needs to delete by comparing them to the application's Creator ID.+ y/ E% Y3 J- Q4 q8 V( r# O9 L* r+ ?
      To sum it all up: The Creator ID uniquely identifies each application including       its files and settings.
& `% m' ~9 A1 W* V      However, some applications save (hide) items       under a different Creator ID than their own; these items will remain on your       device, occupying your precious handheld memory for good./ V2 q. k* W% @6 P1 s6 O$ q/ b: v) J

• Cleanup will search the default directory         (usually Palm/Launcher).
• If you're using a 3rd party launcher or         an application such as PowerRUN to move applications to custom directories         on the expansion card, select the         [+]         button, navigate to the directory you want to include and tap Add         in the subsequent dialog. To remove directories select the directory from         the list and tap the [-]        button (v3.40b and up).

            Cleanup opens each and every application, then, it searches for       the selected item byte value (Creator ID) in its code resources.3 y* v. R7 r3 l1 z
      Cleanup reads the database "byte by byte" to find the searched value.- m/ H; L* n. ^! K$ q
      When Cleanup finds the value within an application, it will be added to the       results page.

When         you are certain you know to which application the item belongs to, you can         restore the backed-up item.

      By moving Creator IDs to the Safe List, you       can concentrate on the unknown items, the ones you're not sure if you need       or not: Cleanup will not list items saved under a Creator ID that appears       in the Safe List.6 W$ v* m( A. E2 m0 B  Y. Q
      

• When moving items to the Safe List, you can write a short description         to go with each item. The description is visible when browsing the Safe         List.
• You can remove items from the Safe List and make them visible again.

            The Signature File is a growing collection of known 'hidden' Creator       IDs that certain applications use to save their data and of other system components       that are not associated with a single application (for instance, the Graffiti       Library which is needed by all applications).

• Preferences: Relatively         small pieces of data programs save that later can be easily accessed when         needed (much like the Windows® registry). Palm OS programs use preferences         to quickly store and retrieve their settings at a later time.
  $ f' H. j8 U* X- K; `' J+ K( e/ [        There are two Preferences Databases on your device used to store these records         of data:

  - @) y/ K. v+ A1 o* k8 R# d        Although the preferences applications save are usually small in size; if         you have many preferences records left by old applications (usually remnants         from Trialware software that were not completely deleted) it can considerably         slow down your Palm Powered handheld.
• Database Files: Applications,         documents, pictures, music, alarms, etc.
• RAM: The Main Memory. When         you run applications, they save their data (files and preferences) in the         RAM.
• Creator ID: All items that         are saved onto your device by installed applications include a reference         (identifier) to the application that created them: Creator ID.         
• Items: Database Files and         Preferences.

      ALWAYS       backup files and preferences before deleting them.1 e7 S- z3 r/ F, o% G+ |
