POSIX_ACL_ACCESS and DOSATTRIB file deletion

Post by Stoompf » Wed Nov 10, 2021 1:34 am

Hello everyone.

We recently recovered files from a Linux based device to a Windows device. Lots and lots of POSIX_ACL_ACCESS and DOSATTRIB files for those recovered files are being shown in the folder. Is it safe to delete those POSIX_ACL_ACCESS and DOSATTRIB files for Windows use? It's a huge clutter, but we don't want to risk any corruption in our recovered files.

Thanks in advance, any help would be much appreciated!

ACL = Access Control List. This is how Linux (and other Posix-compatible) file systems control the access to those files. Similarly, DOSATTRIB is a file that contains Windows extended attributes for the file on Linux file systems. You may safely delete them, and noting is going to happen with the recovered files.

However, if you plan to copy those files to a Linux file system, you may think about copying them to preserve ACLs and Windows attributes, too. But be cautious, as they may create a mess because they may contain references to a user unknown to the system, for example.
