I am continually adding features to fullfill my idea
for an extension editor. Although nobody reported any
malfunctions, I take no responsibilty for any damages
this software causes to your computer.
No installation required, just unzip to a directory and
run gfte. Uninstall, just delete the gfte directory.

GFTE. GFTE will work with Windows 2000 and
Gunners File Type Editor allows you to you to

.txt extension is Notepad. GFTE allows you to change
Admin Mode allows you to change properties for
extesnions system wide, you can set Notepad++ to open
all txt files for all users, until the user changes
