File Permissions

Does anyone know what I can do when Mylio will not allow any changes to photos because it does not have permission? The folders of the originals are in a windows folder that is shared with read/write permission for everyone. HELP!

First, an exact error message would be helpful.

Second, since you say the folder is “shared”, I assume you mean over a network? Is it possible the photo(s) in question are open in some other app, or on some other computer (and therefore “locked”)?
