Opening ONE files
Did your computer fail to open an ONE file? We explain what ONE files are and recommend software that we know can open or convert your ONE files.
What is an ONE file?
The files that contain the .one file extension are most commonly created by the Microsoft OneNote computer software application. OneNote allows users to take free-form electronic notes on their computer by using typed or handwritten input. These notes are then saved to the user's hard drive with the .one file extension.
The OneNote application also allows for audio recordings and advanced searching options. Files with the .one extension usually contain text notes that have been saved within the application, but they may also contain pasted clipboard contents and audio or video clips that have been incorporated into a OneNote file.
Software that will open, convert or fix ONE 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.
