If you really wanted to compress it, buried somewhere I have the code that can zlib compress any file in the same format that BAM and MOS files are compressed. The game won't be able to use it until you uncompress it though, so it doesn't gain you much
.
It has been some time since that problem occured and back then I could solve it with COPY_LARGE.
Today the issue has come up again while trying to upload a mod to github which has a limit for single file size. So a tool to compress a WED file from 136Mb to below 100 would be a valuable option.
Does such a thing exist?
The largest WED file in any of my games is AR1800.WED from BGEE at 376 KB. How (or maybe why) in the world did you need one ~3 orders of magnitude larger??
I will investigate that with Argent77 help - I assume the big size is some error (although there is no problem in the game with that file) it probably contains some overhead that can be removed.
This is the questionable file
