File upload error.

TXT OR DOC FILE NOT UPLOAD MY FORM

I've tested your form and I was unable to replicate the issue you're mentioning, I can upload some files including the formats you mentioned: 

I can see the submission was sent through without any problem too, I would suggest you to check the allowed file types: https://www.jotform.com/help/29-How-to-Change-the-Allowed-File-Types-Extensions-in-the-Upload-Field 

And also check the max upload size of your form: https://www.jotform.com/help/33-Changing-the-File-Upload-Size-Limit 

If the problem persists, please let us know if you're receiving an error when submitting the form or when trying to upload the files, provide us a screenshot of it too, that would be helpful.
