Error

[Jimmyouyang]

Why is this error pop out so many times while I was folding, is there anything wrong with my laptop?

This was one of the example

Do you run a program which examines data in the work sub-directory? The most common cause of this error is if you've opened one of FAH's work files. When a WU finishes, FAHClient cannot clean up old files if you're looking at the file.

[Joe_H]

An additional cause can be improper installation of the folding client which places components into the wrong directories. Then the client does not have the permissions needed to cleanup files. If you could post the first 100 or so lines of your log file, that would be useful.

Thats today's log

Mod edit: added Code tags - j

[Ricky]

I had this problem when I first started folding in windows. A reboot would fix it for a time, then it would re-occur. After time, I no longer needed to reboot. I believe that another program fools the operating system to lock the file.

[Jimmyouyang]

So will this error affect the result?

[bruce]

The message indicate that the first WU was completed normally and uploaded successfully. What happened to the second WU which failed is unclear.

Assuming there's some undiagnosed permission problem with (som ofe?) the files inside of \WORK, the problem can persist and may, in fact, get worse as files that FAHClient fails to clean up accumulate.

Try this: Set your FAHClient to FINISH. All active WUs should proceed to 100% and the results will upload and no new WUs will be downloaded. Once that process has been completed, you can delete the \WORK folder and everything in in. When you restart the client, FAH will recreate the \work folder and new WUs will be downloaded. This SHOULD reestablish fresh work files with the proper permissions -- and (I hope) get rid of the problem..

Questions:
* When you installed FAH, did you select "Just for me" or "for everybody"? The "everybody" option sometimes causes problems similar to the ones you're reporting.
* Depening on that answer, do you always run FAH from the same Windows user "szyan"?

In fact, I forgot if I select "Just for me" or "for everybody" but I know that I always run FAH from the same Windows. But 2 days ago I reset the whole FAH because of a bad WU that can't upload or delete. The problem is that error happened a lot of time before my reset FAH. So I don't know what's wrong with my laptop. My another laptop works fine and never show this kind of error

[bruce]

Reinstall FAHClient and be sure "just for me" is selected. After doing that, it's possible that there may still be older files that were created with the wrong permission that will need to be deleted as specified above ... or you can just select "delete data"

If that's what you just did under the heading of "reset FAH" you shouldn't need to do it again.

[Jimmyouyang]

I reset everything on fah and I did everything you guys say, but the error still pop out every time especially with the bigWU.
Why is this things always happened to me on this laptop? the another one of mine works fine.
