Files with no file extension

Did your computer fail to open a Extension-less file? We explain what Extension-less files are and recommend software that we know can open or convert 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, but when the file extension is missing, Windows does not know what to do with the file, as 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.

Free File Viewer is able to open more than 200 different types of files. The program is free, and after you have installed it, you simply right-click on your file and select "Open with Free File Viewer". We have verified that it works with extension-less files.

It could also be that the file associations are broken on your Windows installation. We recommend that you run a free scan with Registry Cleaner Pro to see if your system is damaged.

Software that will open, convert or fix extension-less files

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
