New to the forum ... but you can create a quick link to an FTP site - just like a drive letter in the tree that works all the time for me. If this is like ... old news ... then forgive the forum newbie.
I prefer the drive list to be centered between the two pane lister layout - from back in my Amiga days. So that is how I have it configured now. I wanted the ability to quickly connect to some of my ftp hosts without having to go to the top menu and choose the ftp site from the drop-down list. I wanted to be able to click on a drive button in the center layout and have it take me to that ftp site.
It ended up being very easy.
IF you don't already have the drives list visible, do the following:
Right mouse click any blank area of the menu bar
Choose Customize from the pop-up menu
From the 'Toolbars' tab, place a check by 'Drives' and
You should now see a listing of all the drive letters available on your system. If you have a dual pane layout - and wish to have the toolbar sandwiched vertically between the two panes, click-and-hold the left mouse button over the the series of dots "...." on the left most end of the 'Drives' toolbar and drag you mouse over to the middle of your screen and drop it between the two panes in the lister.
Now the fun part.
In any blank area of the menu bar - right click and choose 'Customize' - then minimize the customize dialog box that appears. Next right click over a blank area of your 'Drives' toolbar, and select 'New Button' from the pop-up menu.
Now, right click over the 'New Button' that was just created and choose 'edit' from the pop-up menu.
Rename 'New Button' to 'FTP' or whatever you like - it doesn't have any impact on function.
In the 'Function' drop down menu, choose 'FTP Site List'
Click 'OK' and Voila - you have individual clickable menu buttons for each FTP site defined in your sitelist.
You may need to go back into edit your sitelist to rename the site to fewer letters to work better with a vertical 'Drives' toolbar layout ...
for instance, I have 'ftp.mybigfathost.com' as the host name and the host address. Directory Opus auto resized the button toolbar to accomodate all those letters. YUK. So I went to 'FTP' - 'Edit Site List' and I changed the host name portion to a three letter shortcut 'BFH' ... you could use just a single letter - but that will not impact access - only appearance on the 'Drives' toolbar and in the Site list itself. Now when I click 'BFH' in the Drives list - I am taken to that ftp site in the active lister pane. I have several FTP sites defined - so they all appeared as clickable buttons from this one action.
