Acceptable File Types

A file's "type" is expressed as a mime type, which can be obtained (inaccurately) from the file's extension or by peeking into the file itself. Using the extension to learn the mime type is faster but not necessarily valid while reading a little bit then matching against a database of known type rules generally proves the match but is much slower.

Tuzulo's uploading engine inspects everything invasively. Uploading files is always the slowest part of the process, so the added latency is not noticable by anyone.

Correctness matters – that's why we do it this way. If you've ever tried to open a mislabled file in an application like Photoshop® (which trusts the extension), for example, you'll understand.

Supported

We accept these file types:

  • .doc – application/msword
  • .pdf – application/pdf
  • .ps   – application/postscript
  • .xls – application/vnd.ms-excel
  • .ppt – application/vnd.ms-powerpoint
  • .swf – application/x-shockwave-flash
  • .zip – application/zip
  • .txt – text/plain
  • .rtf – text/rtf
  • .jpg – image/jpeg
  • .gif – image/gif
  • .png – image/png
  • .tif – image/tiff
  • .bmp – image/bmp
  • .dcm – application/dicom
  • .psd – image/psd
  • .psd – application/x-photoshop
  • .psd – image/vnd.adobe.photoshop§

§ the official mime type for Photoshop® files.

The general philosophy of Tuzulo regarding images is to upload the highest resolution available proportional to time spent uploading. Our tools work their magic best with large files, optimizing them down to smaller sizes. Resolution can't be easily "invented" – going from smaller originals to larger output sizes almost always degrades quality.

Rejected

We reject these file types:

  • application/ogg
  • application/x-dosexec
  • application/x-gzip
  • application/x-msdownload
  • application/x-rar-compressed
  • application/x-tar
  • audio/mp4
  • audio/mpeg
  • audio/wav
  • audio/x-aiff
  • audio/x-mpegurl
  • audio/x-ms-wax
  • audio/x-ms-wma
  • audio/x-pn-realaudio
  • audio/x-wav
  • video/quicktime
  • video/mpeg
  • video/x-flv
  • video/x-ms-asf
  • video/x-ms-wm
  • video/x-ms-wmv
  • video/x-ms-wmx
  • video/x-ms-wvx
  • video/x-msvideo

Rejection means the above file types cannot be uploaded individually, and if found within an archive causes the entire archive to be rejected.

Inspected Archives

We inspect (yes, invasively) the contents of the following archival file type:

  • application/zip

If any of the contents of the archive match a rejected file type the containing archive will not be included along with the contents of the archive. However, we will extract and upload everything else.

By default and when nothing has been marked as rejected the archive is uploaded together with the expanded contents. You may elect to remove it or change its position within the content list.

Lastly, only the size of a compressed archive is counted towards the upload limit.

Skipped

Items which are neither supported or rejected are skipped but may be included in archives.

Archives within Archives

No, that's not currently supported. We might consider supporting it if enough people ask.
