Windows 2000 Tips
complicated; check the Windows 2000 Help file, which is explicit if not particu
larly illuminating. The functions are listed in Figure 1.
File Management
Short File Extensions
If you try to delete all *.htm files you'll kill those with .html extensions as well;
Windows 2000 evaluates file extensions on the first three characters, as does NT.
You can disable this attribute in the registry, however. Go the key HKEY_LO
CAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem and find
the value Win95TruncatedExtensions. Set it to 0 to disable the first three charac
ters only rule; if you wish to restore the default and turn the feature back on, set
the value to 1.
Previewing Images In Folders
Windows 2000 gives you the option of previewing images in folders not just
displaying them as thumbnails, but actually showing a preview of a selected file
in an Image Preview window to the left of your file list. You can turn this on for
an individual Windows Explorer folder by going to the View menu and selecting
Customize This Folder. When the Customize wizard starts, click Next and then
select Choose or edit an HTML template for this folder. Click Next again. When
the template list appears, select Image Preview. Click Next then Finish.
The Image Preview is more than an oversized thumbnail, because you can use
the buttons on top of the preview to zoom, pan and print the image. Hold down
the Shift key to temporarily reverse the zoom direction, or hold down Ctrl to pan
around the image. For example, if you've zoomed in too far, don't bother selecting
zoom out just Shift click in the preview to zoom out. And while you can pan
around a large or magnified image by using the scroll bars, you can hold down
Ctrl to achieve the same effect: just Ctrl drag in the preview area, the pointer will
change to a hand, and you can pan as much as you want.
Highlight Compressed Files
It makes good sense to highlight compressed files in the Windows Explorer. With
any Explorer window open you can set this option under Tools|Folder Op
tions|View|Display Compressed Files And Folders With Alternate Color. The
default colour for this is blue, but you can select a different colour for compressed
files with a registry tweak. Find the key HKEY_CURRENT_USER\Software\Mi
crosoft\Windows\CurrentVersion\Explorer and locate the value named Alt
