What is a WLT file?
A .WLT file can belong to several different software applications. The most common use is the Unity Window Layout File created by Unity Technologies to store user interface arrangements for the Unity game engine editor.
Another frequent use is for secure data storage. The Ilium Software eWallet uses .WLT files to store encrypted passwords and personal information. Similarly, the NEM Nano Wallet uses the extension for cryptocurrency wallet data. Other hardware devices, like Wolfbox dashcams, use .WLT for locked video files to prevent the camera from overwriting important recordings. Less common uses include CAD layer data for Winstar-Lap and game data for Anstoss 3.
How to open WLT files?
Because the .WLT extension is shared by many programs, you must know the file origin to open it correctly. You can load a Unity Window Layout File directly inside the Unity editor. You must open eWallet data files using the Ilium Software eWallet application. If you have a locked dashcam video, you can often play it with a standard media player like VLC media player.
If you do not know the source of your document, viewer.online/wlt can analyze .WLT files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and troubleshooting
Always keep a secure backup of your .WLT files before you modify them. This is especially important for cryptocurrency wallets and encrypted password databases. If a dashcam video file fails to open, try renaming the file extension from .WLT to .MP4 or .AVI. Do not share wallet or password .WLT files online, as they contain highly sensitive data.
