Hello I don't understand. You are the one, who editing the file - you lock it. Nobody else shoudn't edit it. If file is changed, PSPad will tell you it and allows you to reload it. You are the one who edits file, so there is no information about file is locked.
External programs don't know nothing about LCK files. You can use R/O attribute method, if you want to edit file in different editors. -- <http://forum.pspad.com/read.php?6,62659,62663> PSPad freeware editor http://www.pspad.com
