some zip/portable uninstall options

[Pino (pino1536)]

Actually there are no ways to modify the uninstall behavior when you don't use an installer that has its own uninstaller (zip). WinGet only uninstalls the files from the original zip. This means even new files in an Local\Microsoft\WinGet\Packages\X__DefaultSource directory will not be removed. (+ temp files at other places)

• For Portable packages stored in "PackageID__DefaultSource" it would be better to simple force remove the whole directory.
• We need a way to define directory's and files that gets uninstalled too. (manifest or file in the zip)
• Maybe even a cmd file that gets triggered to clean remove everything that could be generated by the application.

example could be "bun". its uses a clean zip file without a bling bling installer which is commendable. but the disadvantage of it: the whole .bun dir with massive cache of nodejs packages will not be uninstalled.

winget uninstall <query> --purge should remove all files within the package directory for a portable package.

You can set this as the default behavior in your WinGet settings file.
