I understand your use case and it makes sense but they can't really bill an app as portable if it doesn't meet the industry definition of portable. Perhaps they could include a tool that you could use to take a snapshot of existing file associations, set file associations to xnview, then later restore file associations to the snapshot so that it could leave the OS exactly how it found it.

to make this MO really work while also utilizing the 500 file-formats capability of XnView- a big REG file would be needed, which with just two clicks would associate different formats with portable version of XnView
I tried using

Code: Select all

Windows Registry Editor Version 5.00

but it did nohing

I have associated manually [via right click context menu] JPEGs with my portable version and tried finding this association within Registry using Registry itself and few free tools by NirSoft, but failed at this task

Then I tried adding for JPGs [i.e. without E] this hack

Code: Select all

"Content Type"="image/jpg"

@="\"C:\\My-Portables\\XnViewMP\\xnviewmp.exe\" \"%1\""
but even after reset of system JPG files are still opening in the installed version and not in the portable one

Then I read this viewtopic.php?p=186546#p186551 and came to the conclusion that apparently writing a proper REG for this automatic association of various formats to portable version is either impossible or too complex
