Note that file types supported by the NetSuite API are different than those supported natively in their UI. This means that certain file types can be added in the UI but cannot be added via apps like CloudExtend that need to communicate via the API.
For a full list of file types supported by the NetSuite API click here (a list as of Nov 2022 is also below). If the file type you need is not listed please contact NetSuite to file an enhancement request.
