Dreamweaver’s check in and check out functionality can be quite useful when working with more than one person on a site but it creates heaps of .LCK files.
If you want to remove them from the command line go to the top level directory and type this:
find . -type f -name “*.LCK” -exec rm -f {} \;
ahahahaha – sk****w you Dreamweaver and your resource hogging slow cursor movingness!
