Supported File Types and Valid File Names

Valid File Names

Supported characters for a file name are letters, numbers, spaces, and ( ) _ - , .   

*Please note file names should be limited to 100 characters. 

Characters that are NOT supported include, but are not limited to:  @ $ % & \ / : * ? " ' < > | ~ ` # ^ + = { } [ ] ; !

If you attempt to upload a file that has an invalid file name or type you will receive the following error message along with an indicator to the right of your file.

If you received the error message, you would need to remove any unsupported file types and/or rename the file to a valid file name (removing any unsupported special characters) and then upload the renamed document.   If you need to keep the naming convention for storage, you can temporarily rename the file to upload, and then change it back after you have sent the fax.
