1. Adobe Acrobat Reader and Adobe Acrobat PRO DC
If we’re talking about file formats – and we do not only refer to PDFs here -then, Adobe products are sure to impress you.
From Microsoft Office formats like .doc, .docx, .xls, .xlsx, .ppt, .pptx to Text, Rich Text Format and all the way to rather unusual or very specific app restrained formats such as .wpd for Corel WordPerfect, .xps (XML paper specification) and .dwg, .dwt, .dxf, .dwf, .dst (Autodesk AutoCAD) and everything in between – there is no extension that cannot be handled by these powerful tools.
But the support does not just end there. In the Pro version of the Acrobat, you also have a plethora of 2D, 3D, video, and audio formats to play with and you can easily convert them into editable documents that can be adjusted to your rendering needs.

2. TrIDNet File Identifier
The program comes in two variants: a piece of downloadable software or an online version.
It can identify a file type from its binary signature by browsing for selecting a file that you need to analyze.
After a short wait, the results will be displayed and the file accessed and compared against pre-existing definitions from the program’s database.
3. Smart File Advisor
Smart File Advisor can easily identify files that have no extension or have no known compatible software. The tool first analyzes various parts of the file content in order to determine which program to use to open it.
⇒ You can download Smart File Advisor from FileFacts.
4. OpenWith
This program provides users detailed info about file extensions and also links to free software for opening and creating each file type.
It comes with an app that works even when you’re not online. Another great feature is how it can find out the exact software you’ll have to use to access the file after it discovers its type.
⇒ You can download OpenWith from the tool’s official website.
5. FILExt
This is an online tool and one of the best-known for identifying file types. The program includes a large database of file extensions and also includes the software that uses them with a site that features an alphabetical index of 1526 extensions.
You just have to enter the file extension that you’re analyzing into the search box of the program and press the Search button. If it finds the extension in its database, a results page will appear showing the data related to the file.
In the unfortunate case the program does not find the extension in its database, the user will get a link to a page with information on what to do next for more research.
