Unknown xxxxxx.TMP files created in shared folder

Dear Experts,

We have a shared folder and it is accessed by multiple users. User complain that there is some unknon xxxxxx.tmp files created and it makes them difficult to find some folder.
After I google about it quick, I can see it is created by excel files when opened by user.
Some says it is due to Symantec antivirus.  

I look at the file owner and for all xxxx.tmp file, it is owned by only one particular user. Which means it is created by that user profile only .

We have Symantec Endpoint protection installed but it is for all users not for that particular user only.

Could you please advise from where you think those xxx.tmp files are being created ?
And why it is own by only that particular user and why not by any other user ?

For your information, I have checked the parent folder permission and that user has full access to that parent folder and sub folders and files.
Please find the attached screenshot as reference.

I have created a script to auto delete *.tmp files in that directory every 10 minutes.
Since above suggestion didn't help, I would like to set this answer as solution or would like to request admin to delete this question.

Is this user opening files on the share and leaving them open?
The autorecovery settings on the client would create a .tmp file to allow for crash recovery. If the file is not closed correctly the .tmp file never gets flushed out.
Mac clients will almost always leave these files on servers too.

Hi ultralites,

It is windows client. And auto recovery setting in Excel is Unchecked for that user.
I have checked that when there are  xxxx.tmp files created, she has already closed all opened files. But why are those not disappearing ?

Auto-recover option set in Excel is in their user profile location.
But why it is creating xxxx.tmp files in shared folder location?

Is she getting any errors when saving files on that server?

When you work in a file, Microsoft Excel saves the file with a temporary file name and places this file in the same folder as the original file. When you save your file, the original file is then deleted and the temporary file is renamed with the original file name.

If this process is interrupted, your file may not be saved properly or you may find one or more temporary files in the folder where you tried to save your file. In addition, you may receive one of several alert or error messages.

Hi ultralites

The user is not getting any error while saving excel files.

The problem now is it is not deleting the temporary files upon closing excel files.

I have check she has full access to that folder too.

Any suggestion ?

Dear Experts,

Any suggestion on this ?
Ugo MenaCommented:
Have her try this: after she has saved the document, close the document and leave the application open. THEN, exit the program. Does it leave the temp file on the server still?

If so check to see if indexing is turned on within the file share? I have seen indexing services on Mac, lock the temp file and not let Office merge/delete it on save.

I just notice there are some more *.tmp files inside sub folders in that main folder belongs to other users too.
That means not only that user. Even for other user, xx.tmp files are not being deleted upon exciting from Excel 2007.
I'm not sure if it is normal. According to users it was not like that before.

I have created a script to auto delete *.tmp files in that directory every 10 minutes seems solved the problem.
