Extendir is a file system filter driver that significantly increases the performance of your phone, in specific situations even up to 12 times as fast and faster…
Just cook it in to your rom and of you go!


A nice side effect of the architecture of Extendir is that you should have longer battery life!
(I don’t have real test results for this yet so I don't know how much longer you do with your battery but I've heard confirmations.)


But Extendir has also a very nice bonus feature: it can extend your windows directory!
Every file (not folder) that will be installed in the folder “\Extendir\WinDir” or in any one of its subfolders will get a virtual alias in the windows folder. When the OS request the file from the windows folder, it will be redirected to the real location of the file without the OS ever knowing about it.

For example:
When Manila is loaded, the OS thinks all the (900+) files are in the windows folder while the real files are installed in 30 subfolders of the folder “\Extendir\WinDir\Manila”, like this:
\Windows\manila.exe -> \ Extendir\WinDir\Manila\Manila24\ manila.exe
\Windows\68820878_manila -> \ Extendir\WinDir\Manila\Manila02\ 68820878_manila
\Windows\57ad503f_manila -> \ Extendir\WinDir\Manila\Manila17\ 57ad503f_manila
\Windows\7fc62a3c_manila -> \ Extendir\WinDir\Manila\Manila28\ 7fc62a3c_manila
Etc.

But it could also be like this:
\Windows\manila.exe -> \ Extendir\WinDir\Manila\Manila24\ manila.exe
\Windows\68820878_manila -> \Windows\68820878_manila
\Windows\57ad503f_manila -> \Storage Card\ Extendir\WinDir\Manila\Manila17\ 57ad503f_manila
\Windows\7fc62a3c_manila -> (Cooked in rom)
Etc.

This makes it possible to cook roms with 500 or less files in it, while all the other files/apps/etc. will be installed on first boot or later.
Which will bring me to the next application I’ve created:




Preset Installer is an Visual UC application that can create and install predefined sets of cab files and mort scripts.
Cooks can deploy their settings and apps with it, while end users can do the same and save their favorite apps and settings as a preset for future use.






For the better user experience you should automatically start Preset Installer on second boot.



But creating cab files (converting rgu/reg/xml/provxml files, create _setup.xml, all the different file locations to optimize for Extendir) takes al lot of time…
Well… Not anymore:




Extendir Cabs is a utility to create cab files.




Converting packages or your favorite tweaks to a setup cab was never so easy!
The nice part of a setup cab is that you can uninstall it manually or automatically when you’ve got an updated version of the program you want to install.

Info:
Extendir is a file system filter driver that significantly increases the performance of your phone, in specific situations even up to 12 times as fast. The price for this performance is memory. At the moment Extendir caches only non memory mapped files, but in future releases this will be configurable.

A nice side effect of the architecture of Extendir is that you should have longer battery life!
(I don’t have real test results for this yet so I don't know how much longer you do with your battery but I've heard confirmations.)

But Extendir has also a very nice bonus feature: it can extend your windows directory! (The name Extendir makes sense know, doesn’t it?)
Every file (not folder) that will be installed in the folder “\Extendir\WinDir” or in any one of its subfolders will get a virtual alias in the windows folder. It is also possible to have a second (or third) folder “\Extendir\WinDir” on another partition/drive, for example “Storage Card\Extendir\WinDir”. When the OS request the file from the windows folder, it will be redirected to the real location of the file without the OS ever knowing about it, even if the file is located on the storage card. The OS still thinks he’s got 4000+ files in the Windows folder, but in reality these files are spread over 200+ folders located somewhere in “\Extendir\WinDir”.

• Extendir.dll must be added to the XIP.
• Some minor tweaking.

• Removed settings through registry, this was added in v1.01 but that gave major freezes and lockups with some devices. Well now is everything stable, no more freezes and no more lockups!
• Released different versions with different cache settings.

• Fix for lockups for some specific devices in combination with wm6.5 builds
• Fixed some other minor bugs

• Fix for some specific wm6.5 builds

• A lot of speed improvements
• Default cache now 4MB

• Fixed a lot of minor bugs
• Added a few settings to be configurable through registry (boot.rgu)

[HKEY_LOCAL_MACHINE\System\StorageManager\filters\Extendir]
 "Order"=dword:0
[HKEY_LOCAL_MACHINE\System\StorageManager\FATFS\filters\Extendir]
 "Dll"="Extendir.dll"
 "Order"=dword:0

Modify the order of all other file system filter drivers in your boot.rgu. Personally I change order 0 to 10, 1 to 11, 2 to 12, etc. More about the order of the file system filters drivers in Tips and Tricks at post 5
Modify your boot_ms.rgu (also in XIP) if you cooked encfilt.dll/mencfilt.dll in your rom.
Rebuild your boot.hv and port the boot.rgu, boot_ms.rgu and boot.hv in to your XIP. (Ervius and Bepe's kitchens do this already for you)


Now you only have to add the Extendir.dll to the XIP and (which depends on your kitchen) the new boot.rgu to your kitchen.
Personally (in the latest Ervius / Bepe's kitchen) I add the Extendir folder with the Extendir.dll to \ROM\Shared\23017\Extendir (Fill your own XIP build number in place of 23017)

(For obsolete Extendir v1.05 you only have to add the Extendir package and (which depends on your kitchen) the new boot.rgu to your kitchen.)



That was all, but you have to remember that files cooked in to your rom have minimal benefit of Extendir! Files / Programs installed afterwards will benefit fully of performance delivered by Extendir.







A few examples of Files / Programs that fully benefit from Extendir:

• Everything during customization
• Registry
• Temporary internet files
• SMS / MMS
• Everything you (could) sync with active sync (contact, agenda, mail, etc)
• Programs you install
• Files / Documents that you create or copied to your phone
• Etc.

I think the pictures in post 1 are self explaining.
The nice part with a setup cab is that you can uninstall trough Start->Settings->Remove Programs on the system tab when you don’t need it anymore or uninstall it automatically when you’ve got an updated version of the program you want to install.



Changelog:


02.08.2009 - Preset Installer v1.01

• Optional reboot
• Case-insensitive folder/file names (because of manually renaming folders/files)

Info:
Extendir Cabs is a utility to create cab files.
Basically it’s a shell around cabarc.exe.
It converts rgu/reg/xml/provxml files, create _setup.xml, create all the different install paths to optimize for Extendir (optionally you can switch this off). So it’s very easy to convert your tweaks or packages to a setup cab.
About the UI, I think the picture in post 1 is self explaining.

Just one tip: When you create a setup cab for a program and later there is a new release of that program from which you want to make a new setup cab, use the same 'Application Name' so when a user installs your new setup cab, this new cab will uninstall the previous version (the one with the same 'Application Name').

Known issues:
If there are (in an rgu/reg file) HEX values of the type multistring… Well maybe I should google on it.
Also if there is in a value ';' (it's for comments) it doesn't goes right. If it's after a value, used for comments everything goes ok.
For now, cook these values in to your rom.

Possible features in future releases:
Fix for HEX values of the type multistring
Fix for ; in values
(Do you have a request?)


How to install:
Just place Extendir Cabs.exe & Cabarc.exe somewhere in the same folder on your PC.
