100% CPU usage wth FC XE 601 Folder Tree Display on

#1 Post by KingKong » 07.10.2012, 11:35

FC XE 601 is great BUT it seems to have a major defect, namely:-
100% cpu usage if the folder tree is displayed
immediately after any create, rename or move of files.

Over 80% of this 100% cpu usage is due to FC.

This seems to be a BUG in FC because similar problems never occur with Windows Explorer or Xplorer2 (from which I have just migrated to FC).

The problem only occurs if the folder tree is displayed.
It seems that FC is trying to "refresh" all files on the computer, not just those displayed in the other two panels.
100% cpu usage persists for many minutes - I don't know how long because I've never waited for it to finish.
The system does not crash, but all running programs become very sluggish.

The problem can be instantly resolved by simply toggling the folder tree display off and then back on.
However the problem instantly returns at the next file create, rename or move. (File deletion does not generally cause any problem).

The problem is not solved by changing any of the options in FC's Settings (View\file-folder list\refresh)

The problem occurs with both the standard and portable versions of FC.
The problem is not solved by redownloading and reinstalling FC.

My system is Windows XP SP3, Pentium4 2.80 MHz, with about 70G data in several thousands of files.

Conceivably the problem is caused by FC wastefully using resources to compute all folder sizes including those which are not currently displayed. However, other programs manage to do this without 100% cpu usage. (This is just a speculation on my part).

The 100% cpu usage problem I complained aboutyesterday has vanished today!!

Presumably this is because I restarted XP today.
i.e. yesterday XP somehow got confused or a glitch.

Next time there is a problem I must restart system before complaining.

FC is great. Many Thanks.

I am having the same problem as KingKong, but the big difference is my problem did not heal itself.
My system is xp pro sp3 pentium 4 1.5 gb ram.
I downloaded version 601 yesterday and have been fighting with FC using 100% cpu usage between 50% and 80% of the time.
After reading KingKong's post, I toggled the folder tree on and off and the problem cleared itself.
Whenever I toggle folder tree on and do a file create, the problem re-appears.
If I start a download of a YouTube file and folder tree is on, FC immediately causes 100% cpu usage and the system comes to a crawl.
I love FC and hope that this problem can be resolved.

Oh, and by the way;
I started my FreeCommander experience several months ago with version 591 and have not had a problem until 601.
