Supported File Types and Attachments

Although the content of files larger than 5 MB is not indexed, the file names and descriptions still are. MindTouch indexes the content of the file types below (as long as the file is smaller than 5 MB).

  • .pdf – Adobe PDFs
  • .doc – older MS Word docs
  • .docx – newer MS Word docs
  • .pptx – newer MS PowerPoint presentations
  • .xls – older MS Excel spreadsheets
  • .xlsx – newer MS Excel spreadsheets
  • .odt – OpenDocument Text
  • .odp – OpenDocument Presentation
  • .txt – plain text
  • .rtf – rich text format files

Supported image extensions

The exception to this rule is .ico, which is the only supported file type for favicons.

  • .png
  • .jpg
  • .jpeg
  • .gif

Unsupported file types

Please keep in mind that this list is not comprehensive. If you do not see a file type listed in this list, it does not necessarily mean that it is supported. If you are struggling to upload a file with an extension not listed as a supported file type, try saving the file under a supported file extension. Alternatively, you could compress the affected attachment as a .zip file before attempting to re-upload. 

The following file extensions are by default not supported attachments because of security restrictions: 

  • .html
  • .xhtml
  • .htm
  • .exe
  • .vbs
  • .scr
  • .reg
  • .bat
  • .com
  • .vsx
