Locked files

Help & Support
1

During a left to right synch of files across my network, something went wrong. As a result when I try to copy the remaining files across I get an error 5 - Files locked by Opus and I can't copy them
"An error occurred copying 'file name' : Access is denied. (5)
The file is locked by the following process
Directory Opus 10 (path\dopus.exe)

How can I unlock them to get them trasferred. As there are over 3000 please don't say "change permissions on each one"!!!
Thanks.
Ian

My search pre-posting had missed the question a couple of threads down - sorry!
Anyway your answer sent me back to Explorer which also found problems accessing the folders in question. Once I dealt with that Opus worked fine.
