I recently had to reinstall windows due to driver issues and copied all my Steam games in the steamapps folder from the C-drive to another drive, but now I'm stuck with a problem. I have installed Steam again, but when I copy the games' backup to the steamapps folder, and then install the games again, they don't seem to pickup any game files and just starts to download the games again. I have tried verifying game cache, but it just jumps to downloading as well and I have tried modifying the appmanifest files but nothing have worked so far. Any other suggestions I could try before downloading 200GB+ again with a 4Mbps line (500kbps).
Would there be any way that I can make a 'Steam'-backup (backup and restore steam games in the menu) from the games in their folders, with other words, create a bunch of *.csd and *.csm files so Steam can identify it as restoreable?
