I'm not exactly sure how the different priority levels on file handles are done, but I know that some programs let you modify or move files even while they're running, and others will lock the file until they're done.

When fopnu is hashing a file, it prevents me from rewriting that file with another application, and from renaming the folder which contains that file. This is quite a nuisance when I'm working or reorganizing something and fopnu wants to hash several gb first.

Can we give fopnu low priority file handles so it doesn't block writes or renames? It should just release the file and hash it again when it can.

Thank you very much for your help

Windows, fopnu 1.52.
