Notepad Mobile is a “text editor” for Windows Mobile. It allows you to open text (.txt) files and other text based files (.xml, .bat, .log, etc.)

Its main features being high speed, small size and compatibility with most devices running DOTNET Framework.

Release notes:

I am attaching a BETA release of the 1.3 version of this software. Kindly test it and check whether it suits your “open-with” needs.

In general, it should work easily with the explorer you are using. In case it does not, try to use the under-mentioned open-with command.

The “open with” command should be: “/Program Path/Notepad.exe” “%1”

Where ‘Program Path’ is the path of the program and ‘%1’ is the file name. Make sure they are within “double-quotes”.
