About this Zero-byte .SB3 file

What you get

empty.sb3 is 0 bytes. 1kb.sb3 is 1,024 bytes of filler text. Both use the Scratch 3.0 Project name.

Attach either file where your product asks for a .SB3 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.sb3 and 1kb.sb3.
