Hi,
When you open a file with a particular program, Windows automatically assigns that program as the default program for that file type for easy access. However, sometimes we might not want a particular file type to be associated with any programs. When I checked in Windows 8, I couldn’t find any option to unassociate a file type from its default program.There are options to associate that file type with a different program but no option to remove an associated program for a file type completely.
File Types, Encoding: EditPad 7.3.3 ignored the option to preserve the presence or absence of the byte order marker in existing files, using only the option 'write.
However, there is a workaround to unassociate a program for a file type completely. Refer to these steps:
a)Right click on your desktop, select new in the context menu and then select text document.
b)Now, a new text document will appear in the desktop. Rename the text document to “test.exe”.
c)Now, right click on the .obj and .mtl files, click “open with” and select “Choose default program”.
d)Now, you will get a list of program to choose from, click on “Look for another app on this PC” at the bottom of the list.
e)In the browser, navigate to desktop and choose “test.exe”.
f)Now, the .obj and .mtl files would be associated with the “test.exe” program.
g)Delete the “test.exe” file you created in the desktop. Now, the .obj and .mtl files will not be associated with any program.
However, if you open the document again with Notepad, it might be associated with Notepad again. There is no work around top resolve this as of now.
Hope you find this helpful. Feel free to use this forum for any other Windows related queries in the future; we’d be happy to help.
EditPad Lite from Just Great Software is a freeware text editor that replaces Notepad in Windows. It adds up-to-date features like tabs, no arbitrary limits on file size, file conversion, unlimited undo and redo, and compatibility with Mac and Unix files.
EditPad Lite's installer let us choose between standard, portable, and advanced installation options. We selected the advanced option, which let us choose directories and set EditPad Lite as the default text file application, which would open EditPad Lite instead of Notepad when we clicked a text file or opened a new text file from Explorer's right-click menu. We could change it back by selecting Configure File Types on the Options menu; uninstalling the program restores Notepad as the default. EditPad Lite's menu bar adds selections labeled Search, Block, and Convert to the usual complement of items. The Block menu is especially useful; it let us not only indent and outdent blocks of text but also insert files, append text, and Write (save) or Print the selection. The Convert tool handles uppercase, lowercase, invert case, initial caps, and text encoding, and it converts files between ANSI, ASCII, and Unicode as well as Unix and Mac formats in some instances. We could even apply simple ROT-13 encoding and decoding to texts as well. A full-featured, icon-based toolbar added features such as word wrap, fonts, auto indent, and multiple undo options and gave EditPad Lite the feel of a graphics app or word processor. Adding a new tab or closing any or all tabs was easy, too. EditPad Lite offers plenty of assistance and documentation, including a Tip of the Day feature, feedback reporter, and keyboard shortcuts menu.
Pity the poor Notepad, which looks pretty weak next to EditPad Lite. It brings the features and flexibility of a top-class tool to Windows, and its price is right, too, as in 'free.' Highly recommended.
