What is an SFM File?

How to Open, Edit, & Convert SFM Files

A file with the SFM file extension may be an S Memo file used to store notes on a Samsung Galaxy device, with the S Memo app, but this isn't the only format an SFM file may be in.

SFM is also an abbreviation for Standard Format Markers, which are characters embedded into a page of text to indicate a verse, chapter, or other section of a larger group of writing. These plain text files may use the .SFM file extension.

Valve's Source Filmmaker (SFM) tool uses .SFM files too. Some SFM files may instead be DART Pro 98 Soundtree Structure file or accounting form files.

How To Open an SFM File

Samsung Galaxy devices that use SFM files will store and open them as needed. There's really no need, and probably not even a means, to open them from the device itself.

However, if you connect the device into a computer, you may be able to copy the file out of the \Application\Smemo\cache\ or \Application\Smemo\switcher\ folder and then open it with a text editor like Notepad++.

SFM files that are Standard Format Markers should also be able to be opened with a text editor. I think the Adapt It translation program uses SFM files for things like filtering information and navigating through text. Paratext is another program that uses SFM files.

Source Filmmaker opens SFM files that are used with that tool. DART Pro should be able to open SFM files that is uses as Soundtree Structure files.

Other SFM files may be used for accounting forms and can be opened with Sage's accounting software.

Note: Are none of these programs opening your SFM file? You may be misreading the file extension and confusing an SFZ, SFV (Simple File Verification), SFW (Seattle FilmWorks Image), CFM, or even an SFPACK file, with an SFM file.

If you find that an application on your PC does try to open the SFM file but it's the wrong application or if you would rather have another installed program open SFM files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an SFM File

If you're able to open an S Memo text file in a text editor, then you can most definitely convert the SFM file to another text-based format like HTML or TXT.

Standard Format Markers that have the SFM file extension might be able to be saved to another format through the same program that can open the file.

The same is true for Source Filmmaker, DART Pro, and accounting forms that use the .SFM file extension. Any program that supports exporting or converting a file to a different format probably has the option to do so somewhere in the File menu, or maybe through a Convert or Export option.

Note: SFM also stands for surface feet per minute. If you're looking to convert SFM to RPM (revolutions per minute), you can do so with this speeds/feeds calculator.
