Selecting Files and Folders in Windows

Selecting files or folders is rather simple, just left click on a file or folder and it and little highlight will appear around the file or folder indicating that it is selected.  There are however, a few trick that you may not know about that come in handy when working with files or folders.  An important thing to remember with some of these solutions is the fact that they can be used in other programs as well

Drag Selecting
To Drag select, simply press and hold the left mouse button down and select all the files or folders you need.  Once selected release up on the left mouse button.  This works best if all the files or folders are visible on one screen.

Selecting all Files
There are two ways of selecting all files or folders in a folder.  In a folder under Edit select Select All.  If you do not see Edit press the Alt key.  Secondly, and the way I prefer is to simply use the keyboard shortcut Ctrl+A (press both the Ctrl key and the A key at the same time).  Either of these methods will select all the files and folders.

Selecting all Files within a Range
This is a handy for selecting all files between the first file you selected and the last file you selected.  Start by selecting the first file and then while selecting the last file hold down the Shift key on the keyboard.

Selecting only certain Files
To select multiple files that are not within a range, simply hold down the Ctrl (Control) key on the keyboard and start selecting files or folders.  You do not need to select the files or folder in any particular order.  Of all the methods of selecting files, I generally find this to be the most useful and possibly the least known.  Just as a warning, when using this solution be careful not to move the mouse while selecting the file otherwise you will end up copying the files rather than selecting them.  Also, you do need to hold down the Ctrl key the entire time, just while selecting the file.
