Hi, there is an environment variable set by the Portable Apps Platform that point out to the "myflashdrive:\PortableApps" path?
I ask this for some apps have configuration parameters wich point to another app location.
In my case, in Total Commander I can set an external editor, and I usually set Notepad++ for this, specifically my portable usb notepad++ installed on the pendrive.
The problem is: in the path parameter I've to write the full path, example:
G:\PortableApps\Notepad++Portable\Notepad++Portable.exe
But from a Pc to another the pendrive letter change, and I've not much of a control on it, so I'll find very usefull to write something like:
%PORTABLE_APPS_PATH%\Notepad++Portable\Notepad++Portable.exe
This is the very only one feauter I miss from U3

Hi again, I've resolved my immediate problem with Total Commander with a specific environment variable contained in the program, in this way:
%COMMANDER_PATH%\..\..\..\Notepad++Portable\Notepad++Portable.exe
(I calculate the path starting from pendrive:\portableapps\totalcommander\app\totalcommander).
Still I think the PortableApps environment variable can be usefull for other apps with path configuration

The second string: "Sorry for my buddy, it's not terminated"
You can also use %COMMANDER_DRIVE%

i have found that if you use a Truecrypt container (which always mounts to a drive letter you can set) and a cmd file to mount it this problem just goes away. i always mount my TC container to V so all my apps are set to V:\whatever...
example cmd file:
@echo off
IF EXIST v:\StartPortableApps.exe GOTO runProg
TrueCrypt /v nameOfTCcontainer /l v /m rm /a /q
:runProg
exit
Of course you can set "Autorun.inf" on ya flash drive to run the cmd file to mount the TC container, it's all good.
It's good only until you meet a computer which has v: in use.
And it may happen. COMMANDER_DRIVE is a better option and in generic case starting with a script like
and referring to %PORTABLE_DRIVE%.
