Looks good from just looking at it. Will test it myself later.

BTW, could you also add your folder/file cleanup to the admin GPM command to keep things consistent? https://github.com/getgrav/grav-plugin-admin/blob/develop/classes/gpm.php#L203

@OleVik One more detail: I didn't add --force. I didn't find any cache hits. Check this comment for full details.

all-yes works well, but I did notice an oddity in temp-folder creation: One temp folder is created for the .zip-package, another for its extracted contents - presumably they belong in the same temporary cache. Though since both are removed in the process it's largely irrelevant. Had no infidelities on Windows either; all native functions for extracting and moving, and subsequently cleaning up, appear to be working as they should.

Looks good to me.

@OleVik It's the basic and intended behavior.

• copy .zip in tmp/ and run some checks
• extract and check
• install
• cleanup
