File types that support preview and thumbnail generation

Some file type extensions (MIME types) allow thumbnail or preview generation in Alfresco, instead of standard icons. If the file type can be transformed to application/x-shockwave-flash (swf) format, then it supports preview generation. If the file type can be transformed to image/jpeg (jpg) format, then it supports thumbnail generation.

The following table shows the file types that support these capabilities. See Available transform options for a full listing of formats.
