* {{Parameter|fileSpec$}} can include a path that can be either relative to the program's current location or absolute, from the root drive.
* [[KILL]] cannot remove an [[OPEN]] file. The program must [[CLOSE]] it first.
* If the path or file does not exist, a "File not found" or "Path not found" [[ERROR Codes|error]] will result. See [[_FILEEXISTS]].
* {{InlineCode}}[[SHELL]] "DEL /Q " + fileName${{InlineCodeEnd}} does the same without a prompt or verification for wildcard deletions.
* {{InlineCode}}[[SHELL]] "DEL /P " + fileName${{InlineCodeEnd}} will ask for user verification.
* Cannot delete folders or directories. Use [[RMDIR]] to remove empty folders.
* '''Warning: files deleted with [[KILL]] will not go to the Recycle Bin and they cannot be restored.'''
