The folder '%S' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.
Nid oedd modd cywasgu ffolder '%S' oherwydd methodd ysgrifennu i ffolder. Gwiriwch fod gennych ddigon o le ar ddisg, a bod gennych hawl ysgrifennu i'r system ffeiliau, ac yna ceisiwch eto.
