Extension-less File

What are Extension-less files and how to open them

Are you having problems opening an Extension-less file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your Extension-less files.

What is an Extension-less file?

It seems like you have come across a file with no file extension. The file extension tells Windows what type of file it is. Normally, a file has a file extension, e.g. PDF, that can be associated with a viewer for PDF files. When the file extension is missing, Windows does not know what to do with the file because it doesn't know what type of file it is.

If the file was created on a Unix or Linux system, it is probably a plain text file you can open with most file viewers. If not, you may have saved the file using an incomplete file name when downloading it from the Internet.

Bitberry File Opener is able to open more than 400 different types of files. After you have installed it, you simply right-click on your file and select "Bitberry File Opener -> Open". We have verified that it works with multiple extension-less files.
