Often background processes keep files locked.  
I had some expeerience with AlbumArtDownloader, which sometimes locks 1 file in a directory. Since I found this reason for my problems in MP3Tag, I added a process kill in one of my defined tools in MP3tag for AlbumArtDownloader.

Since you mention Flac files:  
Some latest versions of the Spotify player lock Flac files. Spotify, funnily enough, does not declare this to be a bug, but rather a necessary evil to quickly include local music files.

I use LockHunter to have a quick look at such files with a right-mouse-click and a selection in the content menue. LockHunter tells you which process locks the file.
