Hi,

Some problem..

1./ On the network drive, a temporary files "MSIxxxxx.temp" get created. 
(z:\MSIxxxxx.temp) i would like to know when and how it get created. (I think it happens when using ms office)

2./ I also would like to know if this happens because the temp directory 'write' privilege is set as blocked. 
Is the temp folder created on the Network drive directory due to the use of MS OFFICE on the network drive?

Hi,

For your first question, when we open an Office file, Office will create a temporary file like "$filename.xlsx" in the same directory automatically. This temporary file contains the whole contents of your workbook. If Office successfully saves the temporary file, the temporary file is renamed with the file name you specify in the Save As dialog box.

For your second question, this is a by design behavior of Office, we might assign the delete permission to user group of Network drive.
