Hi Andrew.
Recently I figured out that the following application definition:
"%PA_VAR\TotalCommanderPortable\TotalCommanderPortable.exe" \\%0\%1
specifically, because of this \\%0\%1, does not allow the application to appear in the menu when I right-click over any scanned device.
Example:
I can have three apps defined like this:
1) Browse share with TC - "%PA_VAR\TotalCommanderPortable\TotalCommanderPortable.exe" \\%0\%1
2) Browse with TC - "%PA_VAR\TotalCommanderPortable\TotalCommanderPortable.exe" \\%0
3) Browse for Temp Folder - "%PA_VAR\TotalCommanderPortable\TotalCommanderPortable.exe" \\%0\c$\Temp
and only the last two appear in the menu (Open Device > B > Browsers > TotalCommanderPortable > ...) as a choice to pick up.
