Move doesn't work because file is never closed

[johnapickering]

When using the "move" parameter on Windows OS, the following error occurs:

WindowsError: [Error 32] The process cannot access the file because it is being used by another process

By adding the following line immediately after the call to exifread.process_file() the problem is resolved:
f.close()
