SSRS Temp files filling drive

If you have SSRS files filling your temp drive, look for the RSTempFiles.

Default folder:

C:Program FilesMicrosoft SQL ServerMSRS11.MSSQLSERVERReporting ServicesRSTempFiles

You can move this folder to a different drive by copying the RSTempFiles folder to the target drive (for this example “R:RSTempFiles”).

Make sure that the SSRS service account alias has full permissions on the folder

Default local machine service account alias:

[NT SERVICEReportServer]

Locate the rsreportserver.config file

Default folder:
C:Program FilesMicrosoft SQL ServerMSRS11.MSSQLSERVERReporting ServicesReportServer

In this file Located the <Service> tag and add entry for FileShareStorageLocation with new path:

<Service>
  <FileShareStorageLocation>
    <Path>R:RSTempFiles</Path>
  </FileShareStorageLocation>


</Service>

After saving the file restart the SSRS instance.  It should start using the new location.
