I have a folder where I transfer home videos from a camcorder to. I find two files in this folder that are not videos...

  1. .fuse_hidden0000002c00000001
  2. .fuse_hidden0000002600000002

What are these files, and can they be safely deleted?

    @user308564: And, how does that help? – skrtbhtngr Nov 21 '16 at 22:02

You can safely ignore .fuse_hiddenXXXX files. It means a file was deleted but there is at least one software which is still using it, so it can't be removed permanently.

It will be done automatically when the relevant software stops using the file or exists. Such files are always gone after umount/reboot. This is how Linux and any Unix works but only FUSE exposes these files to the user.

These are likely files that were meant to be deleted but are somehow still in use.UBF

    What created these files? – barrypicker Jul 10 '14 at 4:26

    You can find out what application has the file open by using the lsof command. lsof /full/path/name/to/file. These files are also related too the ntfs-3g file system. – Mitch Jul 10 '14 at 8:31
  • @Mitch: lsof /full/path/name/to/file doesn't show anything for my ` .fuse_hiddenXXXX` file. – Tim Dec 8 '14 at 13:57

    Try lsof /just/the/directory/path instead, that lists everything that has a file open in that directory. Worked for me. – dr. Sybren Apr 9 '15 at 9:53

    After a hard reboot, I found a bunch of these files but lsof revealed that no process was using them. I deleted them without a problem and nothing bad happened. – mhernandez Jan 22 '17 at 17:22

Those are just files that tell the camera to recognize these files as it's own and to view them. Delete these files and the camera will not recognize them. Keep them there, they are completely harmless.

  • I doubt this explanation. I see this file in a directory with mostly PDFs. It's also over 500Mb in size. – Dan Dascalescu Jan 21 '17 at 23:47

    You are mistaken (or wrong, or whatever you want to call it). These files are related to FUSE which has nothing to do with the camera. – Rolf May 26 '17 at 13:48
