Portable Efficient Notes is a software application that allows you to take notes in a user-friendly environment. It can be handled by individuals of all levels.

Since installation is not required, you can place Portable Efficient Notes on an external device (like a USB flash drive), plug it into any computer and directly run its executable file. What's more important is that your Windows registry keys will not be changed.

In the list you can view the title along with date of creation and last modification for each note. So, you can edit fonts, add attachments and file links, customize categories, set priority levels and enable spell check.

But you can also use a search function, create notes that will be displayed on the desktop (i.e. sticky notes), backup and restore information, password-protect the program and sort items by various criteria (e.g. attachment, creation time), as well as import and export data.

On top of that, you can change the interface and language, style, enable Portable Efficient Notes to automatically run at system startup and to minimize to the system tray, allow multiple instances, set the location for automatic backups, make file associations, and others.

The simple-to-use program requires a small amount of system resources, has a good response time and didn't freeze, crash or pop up errors during our tests. Unfortunately, we weren't able to access the help file. Other than that, we strongly recommend Portable Efficient Notes to all users.
