TortoiseSVN Switch errors

I'm trying to switch an existing 开发者_开发百科trunk check out to a specific branch, I get this error:

Can't move 
'C:\Work\project123\include\.svn\tmp\all-wcprops' 
to 
'C:\Work\project123\include\.svn\all-wcprops': 
The file or directory is corrupted and unreadable.

I've run cleanup but no change.

If you don't have any local modifications, just delete C:\Work\project123\include, update to get a fresh copy and then switch again. Please backup first!

Update: One of the reasons could be that the files in C:\Work\project123\include\.svn\tmp got locked by an antivirus or some indexing service. To find out which process has handles to these files you can use Process Explorer's search function.

This is a known bug in Window 7, slated to be fixed in SP 1:
