I've been using Neil Rubenking's InCtrl5 for years to track software installations. It's an old PC Magazine utility and used to be free, but now costs, $7.97 (or you can get unlimited PC Mag utilities for free for a year with a $19.97 subscription). It was written for W2K and earlier but works just fine with XP and, from what I understand, with Vista (I don't use Vista, so I can't verify that).

I actually bought EditPadPro recently because there are times when I want to use a stream-oriented editor reather than a line-oriented editor like Kedit, and it seemed to have the best combination of features along with excellent speed and a light footprint, unlike some of the other editors I have worked with (e.g., SlickEdit).  Although I haven't given it a good workout yet, I find it very impressive so far and am very happy with the choice.

That said, folding in EditPadPro is not at all the same as selective editing in Kedit, because folding affects only the display, not the underlying document. In Kedit, you can restrict the editing scope to the visible lines, so that when you mark a rectangular block in the displayed text and copy that block elsewhere, the copied block will contain only the text that was visible in the restricted display. With folded text, the hidden lines would be included in the copy. You can also incrementally add or remove lines from the restricted display by specifying additional targets.

Restricting editing allows you to do things like right or left justify the contents of a rectangular block without affecting the text on the same lines outside of the block. These capabilities make Kedit an unequalled tool for editing flat file ascii databases and tabular data.  On the other hand, you can't search for a pattern that spans multiple lines, as you can in a stream-oriented editor, which is one reason I sometimes need one of the latter.

Perhaps a comment on the increasing subtlety of this thread???
