Overview
This is just to illustrate the purpose of the temp folder that exists in the Filedata folder.
Explanation
The filedata temporary folder is used to temporarily to store files, if for example a client requests the server to download a file. The temporary file is removed afterwards. It is also used to store indexer files. The registry setting for the temporary folder is a valid way to set the temporary folder to another place for e.g. performance reasons.
Some vaults or vault applications may not start due to the location of the temp path being on a network location. Product Development's recommendation is to change the path to a local temp folder on the M-Files Server as a solution.
Registry to Change Path
Registry Key: HKEY_LOCAL_MACHINE\Software\Motive\M-Files\<version>\Server\MFServer\VaultOptions\<vault-guid>
Value name: TempPath
Value type: REG_SZ (String Value)
Value data: <path>
