After archiving, if I need to restore an asset, how do I know which file(s) this relates to in the Archive Folder as the names are quite different?

This can be done in a reverse way. You can copy UUID from the archive folder and go to ‘Advanced Search’ option, and search for that UUID, which will return the required asset. To know the asset UUID, follow the steps below:
eMAM Director:
  • Click on the desired asset under Browse widget. 
  • File versions widget will display the UUID of that asset along with other asset details. See below
