System Files
Download a zero-byte .SYS file, or one of about 1 KB, for QA. Neither file is a real document.
empty.sys is 0 bytes. 1kb.sys is 1,024 bytes of filler text. Both use the Windows System File name.
Attach either file where your product asks for a .SYS 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.sys and 1kb.sys.
empty.sys is empty. 1kb.sys is about 1 KB of filler text, not a real Windows System File.
Most apps will report an empty or invalid Windows System File. That is the point of the fixture.
Yes. Neither file has an executable payload.
