Attachments: Allowed Extensions

Last Updated: Feb 07, 2017 01:22PM PST

In order to ensure the security of all attachments uploaded, Experts Exchange only allows the extensions on the  list below. But, if you need to upload a file type that is not on this list, we can add it to our list of allowed extensions.  

We just need the following information from you:

  • The extension name such as "Microsoft Excel"

  • The extension type such as ".xls"

  • A description of the extension

  • And, a sample file of the extension

Click here to email us. Once we receive this information from you, we send it over to engineering.  Once the new extension is live, we'll email you back to let you know.
