Sometime 7z seems to not extract all the files when dragging multiple folders. Have you tried dragging the UBoat 1.2 folder only from inside the Uboat.7z file?
It seems like this problem sometimes occurs when shift+clicking or cntrl+clicking several folders together and then trying to drag them into the Windows Explorer.
Also the completed 7z for GWX 2.0 weighs in at about 324,327 kb zipped and the unzipped folder (right click for properties) is about .98 gig
Also try to copy the contents instead of moving them to the mods folder. Ie: the copy and extract buttons on 7z.
If you are still having trouble let me know. This is really a nice mod too miss out on!
Thanx JC
