For all the resources involved (QT4), it almost seems silly.
gtk2 is so underrated!
a maximum of 34Meg additional. So yes compaired to TinyCore this is massive, but for a powerful windows machine it is no problem.
no if anything i can't think of a better use for colinux! i do occasionally find myself in front of someone else's machine using windows, and "cotc" would be a lot cooler than tc in qemu! i suspect it would need lots of things recompiled for it though, even if colinux uses native linux binaries, as i believe.
edit:
Emelfm or MC already has a graphic tree structure if you need one.
okay, i've downloaded emelfm and emelfm2 because i've never seen the graphic tree structure. actually i don't care about the "graphics" it's the difference between a tree and a list: a list shows you one level of folders at once, and a tree shows you multiple levels at once in one place, usually letting you collapse parts of the tree. i've been through the settings and not for the first time, unable to find anything like that (or anything graphical either.)
funnily enough, the options dialog itself has a tree structure. it is gnome/nautilus style, having down or side-pointing triangles in a list, but both features of a tree. and yet no way to apply this to any file view. no tree in emelfm, that's why pcmanfm would be so good. trees make managing many folders a lot easier.
as for mc which is a high quality app in general, i've seen its tree view, it actually has one. but because it's a popup and not available in the pane, its merely a quicker way to change folders and lacks most of the benefits of a tree view that go beyond just opening a different list. a side view or pane tree lets you browse many folders on many levels quickly, more quickly than possible in mc- and stays open.
