Archive

This property is True for the files that were not archived.

When the backup software backs up ("archives") the file, it clears the archive bit (makes it zero). Any software that modifies the file subsequently, is supposed to set the archive bit. Then, the next time that the backup software is run, it knows by looking at the archive bits which files have been modified, and therefore need to be backed up

This is the property that differentiates between entries that describe files and those that describe subdirectories within the current directory.

Hidden

This property is True if the file is Hidden.

Hidden files are hidden from an ordinary directory listing.

The Read-Only files cannot be edited or deleted in a common way.
