Temp folder issues

[jadO]

I noticed that XnViewMp uses the system temp folder for thumbnailing. For portable version I don't think this is a good decision. It should use a temp folder in application directory.
Still noticed that the thumbnails for videos get stored there. However they do not get cleaned properly and stay there some times.
Also noted some mysterious lock files from XnViewMP in that folder which never get deleted.

i don't use temp folder, perhaps it's ffmpeg if you use it

I don't think that is correct. In my temp folder I see:

qtsingleapp-xnview-e789-1-lockfile what ever this means

and

a lot of files like "xnview_E14008.png" which are the single thumbnail images.

FFMPEG is not installed and portables as well, so using the system temp folders is bad. But even more worse is that the items do not get cleaned from the temp folder.

From QT api, so i can't change that

a lot of files like "xnview_E14008.png" which are the single thumbnail images.

ok, created by ffmpeg, should be deleted by QT api

That't not good.
