Determining the type of a file without an extension by its content online
This online service will determine the file type based on its content. Even if the file extension is specified incorrectly or is missing at all, the correct file type will be shown for it.
Also, metadata will be extracted from the file, which will give additional information about the file.
The file will be offered an extension that corresponds to this file type – you can rename your file by adding the suggested extension to the end of its name.
If the file is executable, then the existing lines will be extracted from it and other information specific to the executable files will be displayed.
