Earlier this month I noticed that BOINC Manager is often unresponsive or slow. Today, after defragmenting and Windows reboot I had a look at my stdoutdae.txt file, and found the following messages, constantly repeated since June 09

Can\'t rename current state file to previous state file; Access is denied. (0x5)
Can\'t delete previous state file; Access is denied. (0x5)

I suspect that this is the reason for the slowdown, but what could be the problem? What is that \"state file\" mentioned in the message?

(Running on Windows XP SP3)

Possibly client_state.xml and client_stat_prev.xml
If you restored from a backup on a cd/dvd and left these as read_only, then that would explain it.

That was quick - thanks! I will check these two files.

Also found this info how to monitor files http://boinc.berkeley.edu/trac/wiki/Error/Can%27t%20delete%20previous%20state%20file

My suspicion is that it was Copernic Desktop Search. I have stopped the indexing, and it hasn\'t happened since. I need to find out how to exempt the BOINC folder from being indexed.
