7FiveFive NAS - 'File in use' dialog box appears when performing file operations

Issue details

When performing file operations (moves, renames, deletes, etc.) the Mac OS (OS X) finder brings up a dialog message saying that the file is in use, even when it does not appear a program is using the file.

Solution

The cause of this message is often caused by the way that Mac OS (OS X) finder works, by storing folder metadata as hidden ‘.DS_Store’ files. These files can remain open and be used by the OS even when the folder does not appear to be open. To disable .DS_Store file generation on network shares, do the following as an administrator:

1. Open the ‘Terminal’ application

2. Paste the command below
   

   CODE

   sudo defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE

3. Enter your administrator credentials if prompted

4. Log out for changes to take effect
