About this Zero-byte .CPL file

What you get

empty.cpl is 0 bytes. 1kb.cpl is 1,024 bytes of filler text. Both use the Windows Control Panel Item name.

How to use it in QA

Attach either file where your product asks for a .CPL file. Use the empty file for a zero-length check, and the 1 KB file for a small non-empty upload. The download names stay empty.cpl and 1kb.cpl.
