Recommended File Formats for Preservation

The UT Digital Repository accepts work in any digital format; however, submission in a file format listed below is strongly encouraged.  The formats listed below are considered relatively stable and therefore facilitate long-term preservation efforts.  These formats exhibit all or many of the following characteristics: open documentation; support across a range of software platforms; wide adoption; no compression (or lossless compression); no embedded files or embedded programs/scripts; and non-proprietary format.  For additional information on the UT Digital Repository’s preservation strategy, please see the Preservation Policy
