What is an .FLG file?

.FLG is Puppy Linux Partition Flag File

File created by Puppy Linux, an easy-to-use Linux variant; used to mark a certain partition to scan or boot from; referenced during startup and during file system checks; may surface after a bad shutdown of the system; deleted automatically after a successful startup or file system check.

FLG files may appear as FSCK.flg or FSCKME.flg, which are similar to files. These files are accessed by the system and are not meant to be opened manually.

Common FLG Filenames

pupdesk.flg - specifies the startup partition when Linux is started using the PUPMODE=5 parameter. It exists only until the desktop boots up and doesn't get created after that. If a hard/forced shut down occurs, the PUPDESK.flg will be rediscovered during the boot-up and and will force the Xorg Wizard to run instead of starting up the desktop again.
