Bitmap (.bmp) Thumbnails

[LeoGrun]

Maybe I am doing something weird or have not configured something correctly, however Multi Commander does not preview thumbnails for .bmp files.

If thumbnail data is already generated by windows, Multi Commander will use it.

Instead, I see the icon for my default image viewer in windows (Ifranview, in this case).

Is there a way to make Multi Commander show/generate thumbnails for bitmap images?

You mean normal thumbnails when viewing the filelist in thumblist mode ? Not the hover over preview thumbnail ?

Thumbnail for filelist are created by Windows, MC just ask Windows for it. and Windows should create it if not already cached.
There should be no issue showing bmp,

Check this configuration
In Core Settings > FileSystem , under Tweaking.
Makesure Thumbnail system is set to Auto or Windows.

Also if "Log thumbnail process" is enable you should be able to see error from MC get from windows when fetching thumbnails in the log.. (Ctrl+L)

It was originally set to 'auto'. I changed it to 'windows' just to test. It did not make a difference. I wasn't able to see anything useful in the log.

I changed the number of threads from 'auto' to '2' and it is now working as expected. I can't say conclusively why this made a difference, but I'm available for questions about my system and configuration of you would like.
