What are the .preveil-nosync.ptr, .preveil-nosync.jobsdb, .preveil-nosync.filesync_state.xml, and .preveil-nosync.barrier files in my local sync folder?

Open

The .preveil-nosync files are program files that work with the PreVeil Drive sync operations. You will see these files in Windows Explorer if File Explorer options are set to Show hidden files, folders, and drives.

Please do not interact or delete these files. Doing so can lead to unintended consequences. PreVeil advises to ignore the nosync files.
