You already imported all your files into Vault. However, you have an additional source of metadata, which you need to apply to your files. A manual operation is not an option.

dataLoader reads a CSV-file containing your metadata and automatically updates every file with the matching metadata. It even recognizes information like category, revision and state in the CSV-file and applies those properties as well.

If you have a text file like a CSV (with Comma Separated Values) dataLoader will apply the values from the text file to the according file properties. Via dataLoader you will be able to define which property shall be filled and you may configure whether lifecycle state, revision and category shall be updated. In case some files cannot be updated, such records will be reported separately, so that a second import with just such data can be repeated.
