It is higly recommended to store all you portable apps in a PortableApps folder at the root of your drive (flash or hard disk).

Custom use

The launcher (*Portable.exe) backup local and restore portable settings before launching app. When app is closed, it backup portable and restore local settings. Local settings are registry entries and files or entire folders in host computer, portable settings are stored in Data.
The launcher create and use *Portable.ini file customizable by user.

Disabling splash screen

Although the splash screen does not delay the launch, you can disable it with:
DisableSplashScreen=true in *Portable.ini

You can also put your own splash in Data (must be .bmp with transparency magenta) and write:
SplashScreenName=MySplash in .ini (for MySplash.bmp)

Passing parameters

Launcher pass receipts paramaters to main exe:

  • a file dragged'n dropped on launcher will be opened in portable app
  • a type of file associated to launcher (Open with...) in explorer will be opened in portable app

In abnormal use you will get some error messages:

Check if main exe exists

"...was not found in..." tell you that files expected are not in good location (if you run launcher alone).

Check if main exe is running

"Another...is running. Close..." tell you that another instance (local or portable) of main exe is running.
You can disable this check with AllowMultipleInstances=true in .ini.

Check admin rights

"You are not allowed to write to the registry!!" can explain that portable don't run or not properly.
You can disable this check with CheckRegWrite=false in .ini.

Check good exit

"Last exit of ...Portable did'nt restore settings." appears if Windows crached or was shutting down while portable was running: launcher did not have been able to restore local and backup portable settings and will do it before a new launch (recommended acceptance).
