I would like to configure Windows 7 to open every new .txt file into the first of the existing TextPad instances.
I know how to open new files all into a single TextPad instance but I am trying to avoid disabling multiple instances.
Instead, if multiple instances are open, open the new file in the first (or last, if it can be configured) instance.
I remember it used to be able to be done in Win2K and Windows XP under File Associations and there was something like a command options field where there was specific syntax that enabled this. So back then, I was indeed able to perform this functionality.
