By default, WordPress allows uploading of only certain file types. You can add or remove from the default list as needed.
Steps to Editing Allowable File Types in WordPress
- Go to Settings and select the Settings submenu.
Note: On a WordPress multi-site installation, you must be in the Network Admin area. - Scroll to the bottom of the page to the upload file types field.
- It will display the following file extensions:
“jpg jpeg png gif mp3 mov avi wmv midi mid pdf” - You can add additional extensions to this list to allow uploading of additional file types. Separate each file type with a space.
After making this change, you should be able to upload the additional file types. On a multi-site installation, you need only make this change once and it will apply to all sites.
