How to open a file that have unknown format?

hi guyzz i back so today i have a post 4-u that will tell u  How to open a file that have unknown format?
However, you may sometimes come across files that either have unknown extensions or don’t have any extension at all. How do you then determine the associated application that is required to open a file when you don’t recognize the file type itself?

The first thing you are likely to do is “google” for the file extension but there is an easier open as well. Go to Wolfram Alpha and just search for the file extension with the dot (or period) - see example.

Wolfram won’t just reveal the technical details of that file extension – like the developer and MIME type - but also generates a list of software programs that you may use to open that file on your computer – see sample results.

Identifying Files that don’t have an Extension

If a file doesn’t have an extension, you can still identify the format of that file from its signature. All known file types have a standard and unique signature  and this data is stored in the file itself. There are programs that can read this signature* and determine the file format even if the extension is missing from the file name.
The most popular program in the category of file identifiers is TrIDNet. First download and unzip the TrIDNet utility and the associated XML definition files in the same directory. Then open the TrIDNet.exe file, press the “Rescan Defs” button to load the file signatures (you only need to do this once) and then drag-drop any unknown files that you wish to analyze.
identify unknown files
It will show the different file types that match with the file’s signature and you can then use Wolfram Alpha again to learn about the different programs that can be used to open that particular file type. Do remember to rename the files after identification (press F2, prefix a dot with the extension).
