Around 1996-97 I once used this Windows 95 disk space analysis program that had large colorful pie charts with slight depth, a drive bar at the top (like winfile) and possibly a directory tree at the left. The most identifying part of it has been its window caption because it painted a gradient with a large font on the title bar which was striking. The caption could imply use of Borland Delphi (it had that functionality) but there's also similar functionality available for Visual Basic.

It may have either been shareware or commercial software.

This was BEFORE Windows 98 and before I used Windows 98 where there's officially normalized gradient captions.

The closest to the description I know of is Norton File Manager from Norton Navigator, but the caption there is cribbing Microsoft Word 95's with only blue, and I don't think it was a Norton product.

(by the way don't post any links. I'm looking for names and screenshots (under Win95 - NOT 98+) at most. and no useless smug 'just look here <insert shovelware that 99% doesnt have it> maybe u find it' responses either. )
