Opening SGM files

Did your computer fail to open a SGM file? We explain what SGM files are and recommend software that we know can open or convert your SGM files.

What is a SGM file?

SGM is an acronym for Standard Generalized Markup. Files that are saved with the .sgm file extension are written in the SGM programming language.

The SGM language is a document generation language that is used to share information digitally using custom tags and DTD file references.

SGM files can also be saved with the .sgml extension, although the .sgm extension is the more popular form of the file suffix.

The Visual Boy Advance software game also uses the .sgm file extension. These files hold saved state files that allow a user to stop playing the game at any point in time and return to the saved state of the game later on, resuming where he or she had left off.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
