What is a .SDM file?

The file extension .SDM represents a file type known as a Spatial Data Modeling Language File. Specifically, it is used for an email message created with the StarOffice Mail email client. StarOffice Mail was included with earlier versions of the StarOffice suite, developed by Sun Microsystems. However, it's important to note that this file format is not supported by software, which is a related but different office suite.

The .SDM file extension is primarily associated with email messages but "SDM" can also stand for "Spatial Data Model." This is a different usage of the term and refers to a structure used for storing geographical or mapping data, not related to the StarOffice Mail application.

To open an .SDM file that is an email message, you would need the Sun Microsystems StarOffice Mail program. Since this software might be outdated or not readily available, accessing content in .SDM files could be challenging if you do not have the original StarOffice software. There are no current mainstream programs like Microsoft Outlook or Mozilla Thunderbird that support this file format directly due to its association with older software versions.
