By "the different apps that are handling the actual upload", do you mean the clients, or do you have different servers accepting the uploads?
What I meant was that the server (which could be a CGI script or a servlet or an FTP server etc.) would know when the file has finished uploading, so can do the rename whatever. e.g. pureftpd can apparently run custom code when an upload has finished: https://download.pureftpd.org/pub/pure-ftpd/doc/README Search for "AFTER AN UPLOAD".

I do move and rename the file, though even knowing when to move to it depends on knowing when it is fully uploaded. In this case, we have many ways that the files might be uploaded, so I prefer to deal with the file inside of Clojure, rather than trying to customize each of the different apps that are handling the actual upload.
