FileInfo.com contains a searchable database of thousands of file extensions with detailed information about the associated file types. You can use FileInfo.com to lookup information about unknown file types and find programs that open the files.
For the past several years, the FileInfo.com team has worked with many developers, both large and small, to create a central file extensions registry. FileInfo.com is now the central location for developers to submit new file extensions and provide information about file types. If you are a developer, you can easily register your file extensions with FileInfo.com.
You can lookup file extensions using the search box in the upper-left corner of each page. You can also use the Advanced Search feature to search for file extensions by the file type, description, developer, or related programs. For more information about file extensions, view the "What is a File Extension?" page.
