What is the JSN file format?
A file with the .JSN extension is a file known as Shield Now Shield. It belongs to the Encoded Files category. This format is associated with JetSoft Co..
The reliable way to open a .JSN file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .JSN files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
