Hi,

I hope someone's had this problem before and can explain. I'm using XP Pro. When I use Windows Explorer, everythings fine until I go to one particuliar directory. Cpu utilization goes from 15% to 100% if I change to another directory it goes back to 15%. I'm running NTFS on the drive and I've tried disabling just about everything I can.

Thanks for any help and Have a Happy New Year

tony,

go into task manager and then the processes tab. Right-click on the process that is causing the problem and change the priority of that process to a below average one. Let me know if that works for you.

Hey,
I had this exact same problem.. as soon as I went into a directory explorer.exe started chewing up my cpu. I went to delete the file and (after a minute or 2 of waiting) it said that the file was in use and couldn't be deleted. I never even opened the file since the last time I booted the computer. (Go figure?) Anyways, killing & restarting the explorer.exe process didn't help and neither did a reboot. So I got my hands on Process Explorer (it's freeware) and found out that explorer.exe was using the file. So I deleted the explorer.exe reference to the file in question with Process Explorer. Problem solved, I was able to delete the file.

Hope this helps,
Phil

I've noticed this happen to myself, in particular, in a folder of media files of rather large (multi-hundred-MB) size, when the 'Duration' field is displayed under Details. Explorer pegs out at 99% while searching each file ot get the duration, and doesn't stop if the window is closed before all files have their duration listed (which can take a long time with files that size). I believe turning off that detail for that folder will keep epxlorer from pegging out and leaking memory like a dribble-glass.

>> explorer.exe causing cpu pegs - explorer.exe using 100% of CPU
Hello all,

I have had numerous problems with this. Three different computerss three different causes

1.) working with files on usb drives (copying, searching, etc.)
2.) searches
3.) simply connecting to a folder on another computer on the local network

In most cases explorer.exe causes cpu peg and what I find strange is that even once I’ve closed the offending folder task manager still shows the cpu peg with explorer.exe the offender. I end the process then start explorer.exe again for fix until I repeat the desired search, browse, etc.

What is really frustrating is that if you search Microsoft’s site you’ll find only 1 article and it’s offbase. Clearly Microsoft has a problem here and it sure would be nice if they’d spend a portion of their billions to help us with their buggy OS!

WHAT FIXED IT FOR ME in one case:

I opened the offending folder on the local network then changed the view for that folder to details view (rather than tiles). Then I properly closed the window view of that folder (this is important to do before stopping the process) then I stopped the explorer.exe process and restarted it. Problem solved.

Hope this is helpful to others :-)

This problem has been bugging the heck out of me for some time now. For the past two days I have been re-formating and re-installing XP pro (from XP home). The problem re-appeared after I was nearly done re-installing all my soft ware. THEN, XP pro began having these USB device problem ballons pop up. I figured it was simply trying to re-install the device, but my explorer.exe process was bouncing 0 to 100%. I unplugged the Sandisk Imagemate CF card reader, viola, it stopped. I then downloaded the fix from sandisk. What a hair puller!!
