23. Compressing files and folders to save 
space 
Windows XP includes a built in 
compression utility which can save you some valuable space on your hard disk by 
archiving little used files. Working similarly to compression programs such as 
PKZIP and WINRAR, the built in software reduces the space your files take up on 
the disk at the penalty of increased disk access time for the compressed files 
in question. There are several ways of compressing data on your system: 
If you have a pre-existing 
folder and would like to compress everything in it, right click on the folder, 
select 'properties' then the 'advanced' button at the bottom. In the 'compress 
or encrypt attributes' section, check the 'compress contents to save disk space' 
option. 
If you wish to create a 
compressed folder for a file or folder separate from the one it is in now, right 
click on the item you wish to compress and choose 'send to\compressed (zipped) 
folder.' This will create a new compressed folder in the same location as the 
original file or folder. 
24. Open 
explorer window from current command prompt directory 
There is 
a built in command prompt ('start\run' then type 'cmd') command that 
will open a Windows Explorer window to your exact current directory location in 
the DOS-oriented command prompt. Simply type 'Start .' from the prompt to open up 
explorer in that location. And yes, that is 'start(space).' 
25. Using Quick 
Edit in the Command Prompt 
    The 
Quick Edit function allows you to cut and paste text to and from the command 
prompt window, something which you may have become used to not being able to do. 
     
               
           To activate Quick Edit:  Open a command prompt Window 
('start\run' and type 'cmd'). Right click on the toolbar at 
the top and select 'properties.' Put a checkmark in the Quick 
Edit mode box. When prompted, opt to apply changes to all similar windows. 
Now that Quick Edit is enabled 
in the command prompt, you can click and drag to highlight text, then press 
ENTER to copy it to the clipboard. To paste text from the clipboard, simply 
right click on the command prompt window. 
26. Select 'No 
to all' when copying files in XP 
  
  Have you ever noticed that Windows XP gives you the 'yes to 
all' option in its file copy dialog box, useful if you would like 
to overwrite files in a directory with newer files of the same name from another 
location, for example, but fails to offer a 'no to all' option for doing the 
opposite. Kind of annoying if you think about it.  
 What if you have a lengthy file copy operation partially finished, and 
wish to restart it? If you use the default options, you essentially have to recopy 
every file, since saying 'no' to each and every duplicate file will take just as 
long, and cause your mouse finger to fall off. 
  
     Fortunately, there is a way to tell your computer not 
to copy all duplicated files with a single command: 
To do this, when the file copy 
dialog box appears asking you whether you wish to overwrite the first file, hold 
down SHIFT and click 'no.' This will automatically answer no for all following 
files. Note that it will ask you again for the first folder it encounters, so 
follow the procedure again to answer no automatically for all folders. This will 
dramatically speed up the file copying process.
