What is a TSP file?

TSP files mostly belong to Concorde TSP Solver. TSP files serve different purposes depending on the context.
For the most common use, they are employed as Traveling Salesman Problem data files used by the Concorde TSP Solver. These files store graph data that lists nodes and distances for optimization algorithms solving route planning problems.
Additionally, some TSP files are used in other environments:

Configuration Scripts: Used by Keithley instruments, these scripts contain commands and settings processed by tools like Keithley Kickstart or a Script Processor. (Keithley)

Test Project Files: In the TestStand environment, TSP files serve as project files that hold test sequence configurations and parameters.

Telephony Service Provider Files: In some cases, the extension denotes files used in telephony systems for service configurations, sometimes even in executable form.

Proprietary Program Files: A few TSP files are dedicated to specific software applications and their internal processes.

FilExt.com notes: Each version of a TSP file is formatted for the needs of its host application. To open or view a TSP file, use its native software when possible. If the file appears text-based, a text editor can help reveal its structure—just be sure to backup any file before editing.

TSP format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the TSP files comes to the following conclusion:

The TSP file extension is used very often and is used by a few programs, each with its own file format. The two most common formats are as follows:

• 55% of all TSP files start with the bytes NAME crucial for this file format. These files are text files and can therefore be read using a text editor. A typical file size is 2 KB. The file type was created 20 years ago but is still used today. Certain words are almost always found in the files, such as NAME, COMMENT, DIMENSION, NODE_COORD_SECTION, TYPE: TSP, TYPE : TSP and EDGE_WEIGHT_TYPE : EUC_2D. A usual file name is berlin52.tsp or a280.tsp. These files can be linked to burma, kroa, problem, random, bayg, mona, dantzig and bays.
• 3% of all TSP files utilize the Microsoft Compound File format, also known as Composite Document File format or OLE2 compound document format. Compound document files are used to structure the contents of a document in the file. It is possible to divide the data into several streams, and to store these streams in different places in the file. In this way compound document files support a complete file system inside the file, the streams are like files in a real file system, and the sections are like subdirectories. Header signature for the CFB format with 8-byte Hex value D0CF11E0A1B11AE1 (which looks like "DOCFILE"). The internal containers are called CActionInfo, ComponentInfo, Data, Header, PluginVersion, Settings2, TODO User-Defined Tasks and Version. The files are 35 KB to 120 KB in size, with a median of 61 KB. Examples of file names are Test.tsp.

All other TSP files (42%) have different formats, the following 5 formats can be found: EXE, TSEP and Auto. Files like these are sometimes linked to inst, assignment, response, brazil, macro, swiss, table, world or bier.
