Uploaded file reference in DHIS2 web app

We have a web app allowing upload of Excel files. Currently we are reading the file contents on-the-fly and process the data. Is there any way we can SAVE the file in DHIS2 server for future reference?

File data elements can be used for that?

Yes you can design an Event Program with a file data element and every time you save the file, an event is created with some details which you want.

Another alternative is to save files to resources ( found in the Reports menu)
