Hi @sudobob. arduino-cli cache clean has a different purpose than what you're expecting. Whenever you install/update a boards platform (e.g., arduino-cli core install) or install/update a library (e.g. arduino-cli lib install), the archives are first downloaded to the folder specified by Arduino CLI's directories.downloads configuration key, then extracted and installed to the final location from there.

Those archive files are not deleted from directories.downloads at the end of the process. This can be convenient for later installations that need those files, since you don't need to wait for them to be downloaded all over again. However, over time, if you do a lot of platform installations and updates, directories.downloads can get pretty big. arduino-cli cache clean deletes the files from this folder.

I think the documentation of this command could be improved to make it more clear what it does, and we have that on our "to do" list.

I'm happy to tell you that the functionality you are expected has now been added as a --clean option to arduino-cli compile. https://github.com/arduino/arduino-cli/pull/1019 This was just added, so it's not in a release version of arduino CLI yet, but it's in the nightly build if you want to try it out: https://arduino.github.io/arduino-cli/latest/installation/#nightly-builds
