Can you provide some file samples ? I would like to check if it's possible to recover the original filesize from the header.

@cgsecurity

there are a few samples in this archive: https://archive.org/download/micrografx_designer_31/designer.zip

it's in the BEISPIEL folder.

i've used them to make some hexdump and noticed some differences sometimes after the 16th byte. Therefore I've limited the number of bytes to check in the final code.

Thanks for the file sample. I haven't been able to find the filesize but with your patch, PhotoRec can recover the drw files ;-)
