Please describe your issue in as much detail as possible:

I tried to copy a TF2 installation from one disk to another. Steam (going by Windows folder namespace) seemingly does does not distinguish between letter case.

The dialogue window says:

Failed to move all files to the new library folder (Locking Failed).

From content_log.txt:

Can't overwrite existing file "/media/disk1/steamgames/steamapps/common/Team Fortress 2/platform/config/InGameDialogConfig.vdf" (1606 bytes)

When I look at the source folder, there are two case-ambiguous files, InGameDialogConfig.vdf from 2013 and ingamedialogconfig.vdf which is recent.

Issue was circumvented by deleting/renaming the old files, but Steam should still be more case-aware on non-Windows systems.

Steps for reproducing this issue:

Preconditions: Having two files with case-ambiguous names. (in this case ingamedialogconfig.vdf and InGameDialogConfig.vdf)

1. Right click game -> Properties -> Local Files -> Move Install Folder
2. click "Move Folder"
3. get above error
