Hi.
I found an issue in winbox 3.29. when you upload a file into “File List” window into some directory, file name comes with full path. but when you change the file’s directory it will remain the same. unless you reopen the “File List” window.
in my test i changed un-befor-migration.tar file into skins and returning back to rook directory.
