What is the TR4 file format?
A file with the .TR4 extension is a file known as SPICE Transient Analysis Output. It belongs to the Misc Files category. This format is associated with National Instruments Corporation.
The reliable way to open a .TR4 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 .TR4 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.
