Autosizing Explorer

When you use Windows NT Explorer in Details view (choose View, Details), the columns act much the same way as those in a spreadsheet such as Excel or 1-2-3. You can size the columns to fit the contents with a double mouse click. All you have to do is go to the top of the column and double-click the line that separates one column from another. When you do this, the column to the left of the line will resize to fit the longest entry in that column.
