Mesa keeps a history of your files as they change. Every time you upload a new copy of a file, Mesa saves the previous state as its own version. Nothing is overwritten, so you can always look back at an earlier iteration or roll one forward to be current again.

​
File versions

Open a file from My Files to see its version history alongside the document.

​
Upload a new version

Click Upload new version (shown above) and choose a file to replace the current copy. The document you had before isn’t lost: it drops into the version history, and the copy you just uploaded becomes current. This keeps the file’s identity, sharing, and any references to it intact while its contents move forward.

​
Preview and restore

Click any entry in the version history to preview it without changing anything. Each entry shows when it was added and who added it. From the preview, choose Restore to make that version current again; the version that was current moves into the history, so restoring is itself just another step you can undo.
Because restoring only moves versions around and never deletes them, it’s safe to compare a few and roll back if you change your mind.
Reports and Interactives keep their own revision history the same way; see Report revisions and Interactives.

Upload, organize, and share the documents whose versions Mesa tracks.

Attachments and tagging files
