Can i not attach ppt format files?Asked by Adrian on April 25, 2016 at 12:20 AM
I'm not sure I understand, I guess you want to restrict ppt file to be attached.
If you are using file uploader, you can do it by clicking on File uploader and then Extension, only extensions in the list will be allowed for upload.:
Hope it helps, please let me know if you have any additional questions.
