Multiple Excel Temp files


We have been having an issue lately that we are unable to solve.  The network has only 4 PC's all running Windows 7 x64 Ultimate.  All data is located on a QNAP NAS device on the network.  There are a few Excel 2010 files that are used daily by everyone.  Of course, if one person opens it, they have Read/Write Permission and all subsequent users are read only.  For some reason, tmp files are being created in the same folder as the original excel files.  The files are about the same size as the original and sometimes a few KB different.  The files are hidden but build and build until they are taking a ton of room.  We also found that after a bit of time, the original file will sometimes then disappear or you can't access it until the tmp files are removed.
I read at one point that the Office 'Auto Recover' option might be creating these files... we disabled the option and the files are still coming.
Any ideas or help would be appreciated.  Thanks!

I'm going to add the 'Modify' permission to the folder as a few have suggested and see if it makes a difference... i'll report back after the change to see if the .tmp files are still being created.
