What is a LYT file?
.LYT files are used by many different software applications to store layout information. The most common use is as a PCB layout design file created by Proteus ARES. However, .LYT files can also be 3D printer sliced layer files for Lychee Slicer, sign design layouts for CADlink SignLab, or data dictionary layouts for CSPro and SPSS. They can even act as an Adminsoft Document Layout File used by Adminsoft. Because the .LYT extension is used for so many different purposes, the internal structure can vary widely. Some are plain XML, some are compressed ZIP archives, and others are proprietary binary formats.
How to open LYT files?
To open a .LYT file correctly, you must know which program created it. If it is a PCB design, you need Proteus ARES. If it is a 3D printer file, use Lychee Slicer. If you do not know the source, you can try opening the file in a basic text editor like Notepad++ to look for readable text or XML tags that indicate the original software.
Software and tools
Other software that uses .LYT files includes ABBYY FineReader, eCAD, Lantek Expert, and Thermo Scientific Xcalibur. Even older games like Need for Speed II use this extension for UI layouts.
Summary
Because .LYT has multiple possible meanings, it is difficult to know which software to install. viewer.online/lyt can analyze .LYT files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. viewer.online/lyt is useful for identifying, inspecting, and understanding .LYT files without installing software or dealing with compatibility problems.
