You already know that file types are associated by Windows with a single program that can use it.
What that means is that when Microsoft Word was installed by you, it told Windows that if you click on a DOC file then make Windows use Microsoft Word (associate itself) with the DOC file and then Word knows to open it for you.
In easy to understand terms, Windows makes DOC files to use WORD to open them.
DOC is associated with WORD.
Well, that's all good, but what if you have a PORTABLE application that is on your Flash Drive, in a folder on your external
F: drive or also on your local drive? No association can be made because Windows didn't INSTALL and REGISTER it.
DropIt to the rescue again. You can use it as a file associator!
You can create the following association to make your TED (a text editor) on the
F: drive be used when you click on a TXT file, or an INI file:
Open with TED
From the “Configure” button of the Destination field you can also select “
Pause until opened file is closed”. It is useful if you want to open several files one by one, in programs that allow to open them one at a time.
