The .tsl file extension is used by Cenix audio devices to contain audio data. Cenix is a Korean company that develops digital audio recorders. The converter software that handles .tsl files is unfortunately no longer supported by Cenix.
When you double-click a .tsl file, Windows checks the filename extension to recognize the file type. If Windows does not recognize the extension, you will get an error asking you to select an app to open the file.
.Tsl files are created by Subsite Electronics’ TK Series HDD Guidance System. The files log drill pipe location data. The TSR, TMS Plus and TSR Mobile apps can review these logs. Subsite specializes in underground pipe and cable installation guidance systems.
We have provided information on .tsl files to assist users in determining compatible software. Many people share these files without explanations on usage. We hope this guidance helps address that issue.
