ADF files come with many supporting files, which may include other ADF files and XML files. These files are required. The most likely cause for an ADF file not converting is forgetting to upload the required supporting files, or uploading them as a separate file rather than in the Import Options dialog as supporting files for the ADF. To upload the supporting file properly:
- Click the Import Options button () in the Options column for your uploaded file.
- Click and drag your additional ADF/XML files into the External Files box or else click the Browse button, navigate to the files and select them.
- Click OK to exit the Import Options dialog.
Now you should be able to finish the conversion.
