From QB64 Wiki
The KILL statement deletes a file on a relative path designated by a STRING value or variable.
- KILL filespec$
- Filespec is a literal or variable string path and filename. Wildcards * and ? can be used but be careful!
- * denotes one or more wildcard letters of a name or extension
- ? denotes one wildcard letter of a name or extension
- Path can be relative to program's current location or use an absolute path 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 will result.
- SHELL "DEL /Q " + filename$ does the same without a prompt or verification for wildcard deletions.
- SHELL "DEL /P " + filename$ will ask for user verification.
- Cannot delete folders or directories! Use RMDIR to remove empty folders only!
- Warning! Files deleted in DOS or QB64 will NOT go to the Recycle Bin and they CANNOT be restored!
