W&M Digital Archive Acceptable File Formats


About File Formats

Only specific formats of materials can be recognized and supported by the W&M Digital Archive for long term preservation and access. Generally, file formats can be grouped into three groups: supported; known; and unsupported.

Supported File Formats

Supported formats are those that we “will make usable in the future, using whatever combination of techniques (such as migration, emulation, etc.) is appropriate given the context of need”. Simply said, for those supported formats, we will do whatever possible to maintain access to these materials as technology changes over time.

Known File Formats

Known formats can be viewed currently in the W&M Digital Archive, but there is no guarantee regarding continued access to these items over time. It is suggested that materials in known formats be migrated to supported formats for long-term access when possible. For instance, if you have a text document in Word or WordPerfect, it should be converted to PDF before being uploaded to the W&M Digital Archive. Efforts will be made by the W&M Digital Archive to ensure access to known file formats, but submitters are encouraged and in some cases required to convert to a supported format.

Unsupported File Formats

Unsupported formats cannot be viewed currently in the W&M Digital Archive. If your materials are in an unsupported format, please contact Swem Library Special Collections for assistance and to discuss submitting your materials to the W&M Digital Archive.
