Explorer.exe 50% CPU usage

Hei

I have the same problem with my firefox but I couldnt find file.How and where I have to search?Do u have any suggestions

Thanks

There are alternate and easier way, that you can try

1. download free software called Process Explorer from internet
2. Run procexp.exe
3. Find explorer.exe in process tree, right click on it and click properties
4. in properties, click on threads tab
5. in column CPU you will see what thread used cpu on left side, and name of running file on right side.
6. browse your HDD for that file, if you dont know where is it, use search function instead
7. backup file (just copy in another folder or rename file)
8. if you copy file, delete it from original directory
9. go back to Process Explorer, mark thread those us CPU with left mouse click on it and click Suspend button on right bottom corner
10. enjoy

NOTE: if you not sure what is file those you need to delete, first google it for info to prevent your system damage

i'd love to say thank you to Diparnak and of course all of you guys, finally i can fixed the "HIGH CPU USAGE" , and in my case, the file is same, yes that was ".flv" after i uninstall the flv player, everything is fixed,, thanks God,,!!!!

Thank you to all the contributions. I just have one more that solved the same problem for me. In the process of finding a corrupt .flv file, I realized that the recycle bin had thousands of deleted files. I just emptied the recycle bin and the CPU activity went down to about 15 to 20%. So simple it's worth trying.

just made an account to say thanks, for a little while explorer was stuck at 50%, strangely when i ran process explorer it would go down to the normal 0%ish, searched google and found this thread, after visually scanning my desktop i noticed that it actually had two hidden desktop.ini files, deleted one and the explorer usage immediately went down to normal.

thanks

Thank you for the solution. In my case, it was a file with a .asf extension. was only able to delete it from command prompt and after restarting explorer, the problem was gone.

I, too, created an account to reply to this thread. Thanks! I deleted all .flv files on my desktop (I didn't care about their content) from C: drive and once again have control of my computer. Whodda thunk?
