Below are support file types in Open Author. File size limit is 750MB. 


ImageJPEG, TIFF, GIF, PNG, SVG
DocumentsDOC, DOCX, XLS, XLSX, PPT, PPTX, PDF, EPUB

Other file types can be hosted elsewhere online and added to OER Commons as an attachment to an Open Author resource that points to a URL:

Other file types can also be added using "Submit from Web" instead of Open Author. While we do not recommend any particular hosting provider, possibilities include Dropbox, Google Drive, the Internet Archive, and Microsoft OneDrive. The only requirement is that the file's location is publicly accessible (i.e. without requiring logging in).
