All Ways To Open Unknown File Format Windows

If you love to download, then it is obvious for you to come across many formats of file daily. Most of the times it happens that the original format of file is hidden and a vague format extension is displayed in the name of the application. Usually, the extensions of the files are not visible because of the default settings done in ‘Folder Options’ and in this case, if you see an EXE file named as ‘ABCXYZ.pdf’, then you will double click it think that it will open in Acrobat Reader as PDF but then some unexpected might happen. So, if you are suspicious about the true format of any newly downloaded file or you came across any new format of file, then it is advisable to use certain tools which will tell you about the exact file type.


This tool as specified above as FileTypeID can identify all formats matching that file, as mentioned above in the screenshot, I used this application for a ‘Thumb.db’ file which is generally found in all the folders of Windows OS systems. This tool showed the result for the composition of the file, by matching it to different formats and then showing the result. Just drag that file, drop it on the application window and then click ‘Analyze’ button, log will be populated. This tool can also open a file by the conventional method of browsing the file by clicking the button available in front of the file-path field. If you want to see the details such as extension, Created On and Modified On dates or more of a file, then click details button (as highlighted below in the screenshot).


There are other tools which can be used to which can be used for the same purpose and they have already been covered.

Another tool named ‘Locate Opener’ which is really a versatile tool, as it will initially search the application on your system which can open that unknown format-file/application, if it finds any appropriate application then it will display the exe file of that file to the user or else it will ask the user permission to go online and find the appropriate solution for your file, one of it key feature is that you can access this tool from the context menu of any file on your system.



Another solution to find the file type in the default option available in Windows OS, if there is no application installed on the system which can open the file then it will ask you to go online and search for that application (screenshot mentioned below), you can refer to a post here, which will elaborate more on this and a web based service named ‘filext’. You can also refer to another tool which will help you to identify the application which can open that tool, for finding that application the tool will not open any extra browser to tell you about the application rather it will show you the name and link for that tool in its application window itself, you can find that tool ‘’ named here.
