# Replace File

Once a contract is executed and filed into the repository, there may be a requirement in future to replace the document. For example, a contract might be filed with only one signature in place, and a user may wish to replace that contract with the fully executed version. In Aerofiler, this can be achieved by clicking "Actions" and then "Replace File":

A modal will appear to allow the user to drop in a replacement document:

The contract will be immediately replaced. Historical versions are accessible by clicking the "Download" button:

Once a document is replaced, prior versions will no longer appear when searching for document text. For example, when searching for "governing law", even if that phrase appeared in both versions of the contract, only matches against the most recent version will display in Aerofiler.
