The purpose and contents of an .mtst file cannot be determined reliably from the extension alone. This record does not identify a vendor, application, or documented file format associated with it.
Because the format is unknown, its relationship to other files, supported platforms, and current status cannot be established.
No confirmed program is available for opening an .mtst file. The file should be opened only with the application that created or supplied it; opening it in an unrelated program may display unusable data or damage the file.
An .mtst file cannot be converted reliably without first identifying its format and the software that created it. No specific conversion or export method is known for this file extension.
