The thumbnails for Corel Draw and Corel Photo-Paint are wrong.
It seems that for both programs XnView MP uses the 1st thumbnail which generates for all other files.

Also rescale/resample the thumbs in order to show them at the dimensions of XnView's thumbnail.

No, but Xnview Classic crashed when it entered in that folder. Do you want the samples?

Samples sent. Do you want the corresponding BMP/PNGs to see what it should look?

It is block structured, each block has a header ID and a size, so that even a program that works with an old version of the file format can skip the unknown parts of the file and work on the known parts of the file. All RIFF blocks begin on a word boundary so it might be necessary to skip an additional byte. In the present specification, only one RIFF block per file is allowed, and only the RIFF and LIST blocks may contain subblocks.
You'll find a “
RIFF” signature in the headers of .ANI (Animated Cursor), .AVI (Video for Windows), .PAL (Microsoft Palette), .WAV (Wave Form), but also .CDR (CorelDRAW), .CLK (Corel R.A.V.E.) and .CMX (Corel Presentation Exchange) files, if you view them in hex mode.
