A lot of folks here have trouble trying to figure out all the INs and OUTs of Terminal windows, SSH Clients, SSH Servers, SFTP, MC, VI, VIM, XTerm commands, etc

If you've never done all this stuff before, I have empathy for you, really I do. I have bad eyesight and don't type worth a crap, so it is tedious to me at times even if you do have Linux/UNIX experience.

Here's the solution for you Linux non-experts or Noobs.

BEWARE! This gives you FULL Point & Click Instantaneous destructive capabilities!

You will have FULL Root access to your N900 as a drive Letter in Windows.

Ain't no Cryin' in Baseball, remember that. Goes for UNIX too, if you do cry, do it quietly out back...

Very Easy

1) Go to Application Manager, install SSH Client and Server. I don't know if this is in Extras or Extras-testing, or wherever.
2) During install, you will be asked to set the root password, remember this.
3) Install this version of Netdrive from this webpage: http://www.medorion.net/p/24.xhtml Read the page it tells you how to setup to connect a drive letter as SFTP over SSH2.

I set this up on Win 7 in a few minutes.

Drive N: for my N900! Yippeee!

Username will be root
Password will be whatever you set up as

Use the IP address on your LAN for your URL/IP address to connect to.

If this was a help for you, heap some praise on me in the form of the THNAKS BUTTON!

EDIT: I was using Webdrive on my x64 Win 7 because Netdrive doesn't have 64 bit comparability yet(supposedly in a month). The Webdrive is not freeware. I liked it so much I put it on both my 32 and 64 bit systems. You can get it here.

Here's another well reviewed and slightly cheaper option from WebDrive.
