Auto move a document

Hello Rares1055,

Sure, you can build a flow that does exactly that... it would look like this

Trigger: [SharePoint] When a file is created in a folder

Action: [SharePoint] Get Files (Properties Only)

Filter Query: ID ne <ID from the Trigger> and Status eq "VALID"

Apply to Each Result from "Get Files"
  Action: [SharePoint] Update File Properties

  Status: "INVALID"

  Action: [SharePoint] Copy File
  Destination Folder: Your Archive Folder

But i would not go through all that hassle.

Just enable versioning on that document library and always save the file as the same filename.
If you want to see older versions of the file, just take a look at the document history of that file.

Best Regards,
Sven
