Hi Grant,

Because windows has this file open and locked. The locking model prevents concurrent access. The only time you could add that file to git would be when you're logged out and doing it as another user[1].

Thanks -Ben

    whole can of worms I won't get in to.

Did you miss the part where is says "Permission denied"? You even quoted it in the e-mail.

As to why you don't have permission to read the file, that shouldn't be related to git at all. It looks like you're trying to read someone else's data, which would certainly account for the lack of permissions.
