Navigator June 1998

EPOC32 desktop alternative

I hate to keep using the word "unique" when reviewing software from Purple Software, but I can’t help it. As long as they keep it up, I will too. They have a unique product in Navigator, and I’ll let the cat out of the bag right now: I love it! The title may bring to mind some kind of application launcher, or utility for handling file management, and you wouldn’t be wrong, but it is a whole lot more than that. Navigator is a System or desktop replacement that is modeled loosely after the standard Windows 95 desktop that many of us are used to. I'll look first at the main features and then the usability issues.

First, the program itself was a brilliant idea, and I give Purple credit for giving us Psion users an alternative to the Psion desktop. Of course desktop replacements are nothing new on PCs and Unix machines, but this is new territory for palmtops. Navigator can optionally re-map the system button so that it takes you to Navigator instead of the standard desktop.

Getting used to the desktop on any OS is probably the most important thing you will do to get productive, so you will need to give Navigator a chance before you'll be tossing the built-in system screen. The interface makes sense right away to anyone familiar with Windows, Mac, or any other GUI for that matter. Navigator leans more towards the Win95/NT side by incorporating the Windows Explorer style file browser, which they call the Browser. Purple has done a good job in designing the Browser. In fact, it’s far better than the file browser built into the Psion, supporting various icon sizes and typical Windows views. Another issue for me is speed, and Navigator’s browser beats the pants off the built-in browser. I did a test on a compact flash disk with an extensive file and folder structure. Pressing the tab button from the system screen and choosing drive D took 9-10 seconds to draw. In Navigator it came up in 1 second. For me that makes Navigator usable where Psion's browser was not.

Navigator's desktop lets you open multiple windows, and these windows can go off the screen. This way you can have multiple folders open on the screen at once, and just move them partly off the screen if they get in the way. This is crucial when you are dealing with a palmtop with limited screen size.

Drag and drop
What would a Win95 style desktop be without Drag and drop? A joke! Of course Navigator supports Drag and Drop. Dragging files between folders will offer to copy them, or move them if the target folder is on the same disk. Drag and Drop is no doubt one of the biggest reasons to buy this product. I was a bit surprised that the Psion did not support it from the start. The lack of drag and drop makes the current EPOC32 system screen seem a bit less intuitive than it should be.

To customize your workspace you might like to have shortcuts, or aliases in MacIntosh lingo. Don’t worry, it’s there. Files and folders can be dragged to the desktop, which automatically creates a shortcut on the desktop. This way you can create your own desktop, making the files and folders that you use most often more accessible. This feature is a big help for those that create a lot of documents on their Psion. You’ll want shortcuts for the exact same reasons that you want them on your desktop computer. Sometimes files are buried deep in the filing system hierarchy, and become a pain to find. Shortcuts solve this problem.

Next, Navigator introduces a new way of handling the standard Psion toolbar. They have made it adjustable, or user definable. You can select which features you want to be shown in the toolbar. I was able to use this right away since there was a feature that I was using a lot that wasn’t in the toolbar. Last but not least, Navigator has zip (file compression) support that I wish I had in my WinNT unzip program. It integrates so smoothly into the desktop that a ZIP archive looks just like a folder. You create a ZIP file with a single hotkey combination. It opens like a folder, and you can just start dragging files and folders into it from any window. They went the extra mile in the zip support by making sure that files inside a zip would show up with the appropriate Psion icons. When you use Navigator for awhile, it becomes obvious that ZIP support was not an afterthought, but rather an integral part of the design. This becomes even more evident when doing a Find. One of to include Zip files, which causes the search to look through your Zip files for matching text. The search results show up in a separate window, and the items in this window are accessible while the search continues. If you click on a found item that exists inside a Zip file, the selected file is Unzipped, and launched. Very nice!

Minor differences
The main differences initially that Windows users will see are the different hotkeys for closing windows and going up one level. Since the Psion doesn’t have function keys, Alt-F4 and Ctrl-F4 can’t be replicated very easily. Psion-Shift-x closes a window, and Psion-Shift-c goes up one level. After a couple of hours with Navigator these don’t seem to be a problem.

  • I spoke with John Holloway and Chris Hennings at Purple Software LTD, and they gave me some insights and tips into the inner workings of Navigator.
  • Using the Fn key with the "Up one level" button goes up one level but shows the files in a new window. This is a nice time saver.
  • Moving shortcuts from "\system\apps\navigator\workspace" to "system\apps\navigator\copyto" adds the folder to the CopyTo menu.
  • Activating the File/Properties dialog with multiple items selected displays their combined statistics.
  • Holding down the Shift key while using the CopyTo menu does a Move.
  • Ctrl-Tab and Ctrl-Shift-Tab cycles through the current browsers.
  • Create an empty folder "c:\system\apps\navigator\subst "and then restart Navigator. This will cause two new menu options to come up allowing you to substitute disks and clear the substitutions (This does what the SUBST command in DOS does).
