I did as you told, turned off those features, but I still can't copy all the files. Now only 4 of them cannot be moved (instead of 5). And they all are in the same directory (/core/cache/mgr/min).
Am I right thinking that I can just delete the contents of "min" directory? Will those files appear again?

You can actually delete all files in the core/cache directory, in fact it's a good idea to do so after an upgrade.
BTW, the
CacheClear extra will do this for you from inside the Manager.
Thanks for help. Now all my files are copied just fine.
