working on a way to update thumbnails. Refactored the encryption service to allow it to reset modification times of files much better by working with indexedfiles instead.
It works now! Whenever a file is unlocked and it is modified, the thumbnail will be updated. Found out that most applications that modify files leave the original as it is, so this scenario might not happen all too often. However, it works. Just in case.
