What is a LIST file?
A .LIST file contains organized list data. Different software programs use this extension for different purposes. Many .LIST files are HTML files used for mobile device data extraction by tools like Cellebrite UFED and PhoneTrans. Others are JSON files that store metadata for note-taking applications like Samsung Notes and Noteshelf.
Some .LIST files contain plain text. Debian APT uses them to store software repository sources. Microsoft Visual Studio uses them for database lists. Sometimes, the file is a compressed ZIP archive used by Studio 3T for connection settings.
How to open LIST files?
Because the .LIST extension has multiple possible meanings, you need to know the creator software. You can open plain text versions with standard text editors like Notepad++ or Visual Studio Code.
If you do not know the origin of the file, viewer.online/list analyzes .LIST files to identify their exact format and creator software. It shows which programs can open the file, and usually previews it.
Software and tools
Many programs generate .LIST files:
- Cellebrite UFED (Data extraction lists)
- Samsung Notes (Note metadata)
- Debian APT (Package sources)
- Adobe After Effects (Preset packs)
- Studio 3T (Database configurations)
Best practices and troubleshooting
Do not rename the .LIST extension unless you know the actual underlying format. If a text editor displays random characters, the file might be a compressed archive. If you need to use the data in another program, we recommend file conversion to sensible target formats like .TXT, .CSV, or .HTML on convert.guru.
Summary
Because many .LIST files use the known HTML format, viewer.online/list can safely open and display them online, eliminating compatibility problems.
