FIX: Corrupted files are unexpectedly saved to a Team Foundation Server 2010 version control repository


Consider the following scenario:
  • You try to save files over the network to a Microsoft Team Foundation Server (TFS) 2010 version control repository.
  • A network issue occurs, and the files become corrupted.
In this scenario, the corrupted files are unexpectedly saved to the TFS 2010 version control repository. Additionally, you may receive the following error message when you try to open the files in Microsoft Visual Studio Team Explorer, in a command line, or in a TFS Team Build:
The CRC in GZip footer does not match the CRC calculated from the decompressed data.


Important Files that are already corrupted will not be repaired by this hotfix. You must upload the content again and then replace the corrupted files. The hotfix will prevent corrupted files from being saved in the future.
