# Update document metadata
Use this format to update the metadata/properties of documents without changing the version/modified information. The filename should contain updatefileproperties and format is xls(x)/csv.
The following columns can be defined:
ClientCode
MatterCode
Url
SourceFile
... additional columns are mapped on document fields
Specify a clientcode/mattercode to fetch the document library url. In this case the SourceFile can contain a relative path from the root of the document library.
If no clientcode/mattercode is specified, the url column can contain a value for the site or documentlibrary url. In this case the SourceFile can contain a relative path from specified url.
For each unique combination of clientcode/mattercode/url a thread is started with a separate sharepoint connection. To speed up the process it's adviced to specify a mattercode or url.
The other columns that are specified are used to update the fields for the document specified in the SourceFile.
Due to technical reasons on Sharepoint On-Premise the version settings are temporarily disabled during updating the metadate, to prevent new versions of the document.
