I just uploaded a batch of RAW files to my PSCS-6 Bridge on a Windows 7 64 bit machine. They all look fine but I am finding that a few files will not allow me to rename them. It tells me that the file is in use with another application. (no other computer or application is operating). Then I open the same files in PSCS-5 Bridge on a different Windows 7 64 bit machine on a peeer to peer network and the exact same files give me the exact same message on that machine too. It is like I have the files open in Photoshop while attempting to rename them in Bridge, but that is not the case. Other files in this same folder work just fine. Other files in different folders work just fine.
Can you try and select one of that files and with right click mouse menu choose purge cache for selection and see if this changes things?
And I assume you have already checked the files are not locked and you do have read and write permission (admin rights) for them.
I came back to this problem with Omke's suggestion of purging the cache and the problem had self corrected by a total re-boot. I had already tried re-booting the program and I even tried another computer on the network and the file would not rename.
The problem is gone for now. I just wish I knew what the cause was for future events.
There was not a problem with a leading space. Yes, I did try to rename using Win Explorer and nothing would work.
