Testing Files Generator makes real files to test against - an upload form, a parser, anything that takes a file. Pick a format and a size and you get a file of exactly that size, to the byte, that a real reader opens. Every run also writes a manifest saying what your system should do with each file. It runs entirely on your machine.
This package is the desktop window. The command line is the package DonislawDev.TestingFilesGenerator.CLI. WinGet adds no Start menu shortcut for it. Open a new terminal and type tfg-gui. The window offers a tfg-out folder in the directory it was started from. Close the window before you upgrade. WinGet cannot replace a running program, so it stops half way, and the package works again once the upgrade runs with the window closed.
