How to get file from tbl_Content table in TFS

Answer: you shouldn't go there. The TFS database schema is not documented as subject to change, and the query is not directly supported by Microsoft. It actually changes a lot between service packs, let alone releases.

It said. When storing files, TFS uses a combination of zip compression and also stores delta between file versions using the same delta engine that windows uses to handle Windows updates, etc.

In order to access files normally from TFS, you want to use the .NET API or the tf.exe command line to communicate with a valid server.

If you want to modify your question to explain why you need table access, you can point you in the right direction. Are you trying to recover data from a TFS SQL backup or something else?
