ASP.NET - saving temporary files

I have a web form that allows users to upload files when they open a ticket on our system. Downloading is performed using the asyncFileUpload control "ajax control toolkit".

The idea is to save the files in the temp directory and only save them in a permanent place when the user clicks the commit button.

I would like to be able to get rid of temporary files that are no longer relevant (for example, the user leaves the page open for a month without submitting the form).

What would be the best way to not store temporary files forever. Maybe store files in a session? Maybe keep them in view?

I could add JS to the timeout page and add code that runs when the user leaves the page. But these ideas are customer solutions. I would not want anyone to interfere with the code and leave me trash in my system.

Any other idea?

Thanks Summerbulb

In the declaration, you can execute the System.IO.File.Move () command. The remaining files can be deleted using the service or console application, if you have access to the server for this.
