How to change a *.pk3 file name

[kat]

Solution
Changing the name of the *.pk3 (or any *.pk* file) is the same as for any other type of file (for PC). Simply right-click and select "Rename", or left-click twice, with a slight pause between the two clicks, to highlight the name for editing. Retype a new name and press "Return"/"Enter".
