Program Name and MIME Type Info for File Extension .JST

FILExt has been given permission to display a Program Name/MIME type database collected by Anthony R. Nemmer. Some of that data has already been included into the main FILExt database; but, not all. Those entries which have not yet been incorporated are shown below in the hope that they will be of some use. Be aware this is raw data which may require further research on your part to fully understand. MIME type listings often contain the name of a program or, at a minimum, a type of file as the leading text in the MIME type.

General Info

• If the extension you are looking for is of the form .??_ the file is likely a compressed file and part of an install routine. When the install program runs it will expand the file and replace the underscore with the proper letter for the file type.
• If the file is sent as an audio file with any three-character extension it may be a dictation file where the extension is the dictator's initials; playable by BCB Voice Systems software (see ??? extension). The file could likewise be a dictation file in TrueSpeech format. Use Windows Sound Recorder and/or Media Player to play these back.
• If the extension you are looking for has a number at the end or is only a number and there were no results consider entering the same extension format using zero or one as some programs produce numbered split files but when the split can be extensive (e.g., .000-.999) only the first entry is in the database.
