dump/dmp and debug?

what are dump/dmp and debug files in combat arms folder. i have been hacking and wanna make sure i dont get cuaght. so what is it and should i be worried or not. all i did after was delete the files.

Just records of what happened, usually the disconnecting of things. It is common for it being a DLL file of the Combat Arms folder, or a hack dll. As said, its useless
