Note that these file types may be accepted but will not generate an originality report or similarity score.

When setting up an assignment, lecturers should normally select the option NOT to accept "all file types" to avoid the possibility of students submitting the following file types and not getting an originality report.

  1. Microsoft Works (.wps) file types.
  2. Apple Pages file types.
  3. CAD files (e.g. prt)
  4. Microsoft Word 2007 macros-enabled (.docm) files (whatever macro is encoded in the file is stripped away when submitted to Turnitin)
  5. Password protected files
  6. .odt files created and downloaded from Google Docs online
  7. .doc files created using OpenOffice as these are not a 100% Microsoft Word equivalent
  8. zip or rar files
  9. Text with visual effects
  10. Spreadsheets created outside of Microsoft Excel (i.e. .ods)

If a file format issue is occurring, please re-open the file in a word processor, and save the file again using the "save as" function and choose a different format from the file type pull down menu (try PDF).

If you are experiencing problems uploading the paper, please send an email to  and attach your paper to it so that we can co-ordinate with Turnitin and find out what is going on at their end. Also, please let us know the word processor and version you are using to write the paper.
