What is a TSP file?
A .TSP file can belong to several different software programs. The most common use is the Traveling Salesperson Problem data file. This format stores geographic or routing data in the TSPLIB standard format. Researchers and data scientists use these files to test optimization algorithms.
Another common use is the Test Script Processor script created by Keithley Instruments. These files contain configuration code to control electronic testing equipment. A .TSP file can also be a Telephony Service Provider driver used by the Microsoft Windows TAPI interface, an Econometric analysis script, or a project file for NI TestStand. In some systems, it might even be a digital TV DVR recording or a legacy TrueSpeech audio file.
How to open TSP files?
Because the .TSP extension is shared by many different programs, the method to open it depends on the actual file type. You can open TSPLIB data files with the Concorde TSP Solver or any standard text editor. You can view Test Script Processor scripts with Keithley Kickstart. If the file is a Windows TAPI driver, it acts as an executable system file and should not be opened manually.
Best practices and troubleshooting
Do not rename the extension of a .TSP file. Changing the extension will not convert the file format and might cause software errors. Because a .TSP file can be plain text, an executable system driver, or proprietary binary data, you should verify the file source before attempting to open or run it.
Identify and inspect with viewer.online
Because .TSP has multiple possible meanings, we recommend using viewer.online/tsp to identify the actual format of your file. viewer.online/tsp can analyze .TSP files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
viewer.online/tsp is useful for identifying, inspecting, and understanding .TSP files without installing software or dealing with compatibility problems.
