@unarc 125
- what u see in arc is a bug in arc itself it often happen to me , too . all u have to do is reboot ur windows \ move the data archive \ rename it and sometimes leave it for some time then this error will disappear

but u don't have to delete the archive file & make it again
- for bf3 cas files .. better no to use any pre-compressor the difference will only around 50~100 mb so it's better with srep+lzma
