Deleting all the save files and cover letters of PTF from AS400 system

Why is it required to delete the save files and cover letters of PTF's?

Many a times, administrator assume that these would be needed at a future date, so they leave these save files that are created at the time of patch upgrade to sit on system. Gradually, this takes up a huge amount of space on your system. In order to free this place it is  required to delete them. The safe way would be to take a backup of it so that you can restore it back when needed.

*note :- Deleting PTF would not remove the PTF's that are applied on to the system, instead it will just delete the save files and cover letters associated with PTF from the system.

You can check the number of PTF save files by checking the Q* files that sit in your QGPL.

WRKF FILE(QGPL/Q*) FILEATR(SAVF)

You can directly delete these files by taking OPTION 4 to delete. However, this would leave behind the cover letters in the system.
