    Image file names -- any way to ensure they are unique?

    Asked by redmenace on December 15, 2013 at 05:37 PM

    We will have many different users uploading JPEGs.  There is a chance that the files they upload will have the same names.  Is there any way to rename the files on upload to make sure they are unique?  For example, to prepend the user's last name to the filename?

    Hi there,

    Files with the same name are automatically prefixed with numbers when they are uploaded to Jotform so they are all unique, and it's impossible for them to overwrite each other. 

    Unfortunately, there's no way to prepend field data to the uploaded file name so it's not possible with the file upload tool. However, like I've said they are already unique in terms of the file name.

    You might also want to integrate your form to Dropbox or Box so you can create a custom folder names so each submissions creates an organized folder on your Dropbox/Box account.
