I love my XFCE4 (hated it's XFM file manager) ( http://www.musikwissenschaft.uni-mainz.de/~ag/xfm/ )
just like others love their (insert favorite desktop window manager), but I have decided to spend a month or so with each of them so I might have a chance of helping others with their questions, rather than go to my ususal rant that they need to drop 'so and so' and use 'such and such'. <insert>Deep breath…</insert>
So what I started all this to say is, I often use a different file manager than the default for whatever window manager. I know it sometimes means installing the entire mega-sized window manager just to get their gui file manager. But you don't run the whole memory eating desk thing just the file manager.
I found another one last night that is billed as a challanger to kde's konqueror. Check out Krusader, I like their new version 1.5 it seems a big improvment from 1.4. This review on LinuxToday was why it caught my eye:
In the article there is also mention of 'total commander' for the older win boxes some of us have to build/repair for folks. For those of u that may want to look into that.
There is another simular one in development seksi, read about it here: http://freshmeat.net/projects/seksicmd/
Then we also have gentoo, no not the distro but the file manager. http://freshmeat.net/projects/gentoo/ great for those that want to spend hours tinkering with configuring it to do just what YOU want it to do.
There are many other GUI-filebrowsers for you to check out at http://freshmeat.net/search/?q=file+managers§ion=projects&Go.x=0&Go.y=0
