When the "Download Documents to Compressed File" is invoked from a Folder, the latest version of all revisions are included on the .zip, for example, Doc A.5, B.3, C.4.
When there are different documents or versions with the same filename, an [number] is added to the filename in the zip, for example, mydoc.pdf, mydoc [1].pdf, mydoc [2].pdf.
When a Document has different filenames across its versions, it's difficult to relate each file with the according document revision.
So, it would be helpful to include the version info at the end of the filenames, for example, mydoc[A.5].pdf, mydoc[B.3].pdf, mydoc[C.4].pdf.
