'''The Best Way to Rip a DVD or CD from a Disk to an ISO File!'''
+
<br /><br />
−
First, you need to find out some info from the physical disk, so that the image you create is "'''EXACTLY'''" the same size as the original.  Without this info, the dd command used to create the ISO image file will add two additional bytes to the end of the image file.  By first running this command to find out the block size and volume size, you can force the dd command to create the ISO image with exactly the same number of bytes the original disk has!

There is also the wscript command, which is almost identical to csript, other than it being targeted to running Windows based scripts, whereas cscript is meant to run console based scripts - those which run and complete in a DOS, aka, a command prompt window.

(Only one of the below commands are required, depending on your system and how it automatically mounts disks)

This file is usually located at C:\Windows\SoftwareDistribution\DataStore and is named DataStore.edb.

to create a nice ncurses based status indicator while it creates the image, allowing you to monitor the progress of ISO image creation:

<pre style="color:blue">

'''Create ISO Image from Mounted CD or DVD:'''
 
−
* In the example below:
 
−
** Replace "IMAGE_NAME.ISO" with what you want to name the ISO image file.
 
−
** Replace "/run/media/dir_disk_mounted_on/" with the entire path that the disk is mounted on.
 
−
** This exact same command can also be used to create an ISO image containing any mounted directory tree.
 
−
** Switches used in below example: -v = verbose output, -J and -R = Juliet & RockRidge extensions included for Windows compatibility.
 
−
<pre style="color:blue">genisoimage -o IMAGE_NAME.ISO -v -J -R /run/media/dir_disk_mounted_on/</pre>

Microsoft Windows

Info, Tips & Tricks

How to clean up your Windows installation to free up drive space

Windows PowerShell Information

Windows command line tools, otherwise known as powerful stuff you can run from the DOS command prompt

As a reminder, the quickest easiest way to open up a DOS command prompt window is to just click the "Start" button, type cmd and hit the ENTER key!



Keyboard shortcuts to save you time from taking your hands off the keyboard to use the mouse!

Cscript.exe is a command-line version of the Windows Script Host that provides command-line options for setting script properties.

Excellent information on SCript!

There is also the wscript command, which is almost identical to csript, other than it being targeted to running Windows based scripts, whereas cscript is meant to run console based scripts - those which run and complete in a DOS, aka, a command prompt window.

Windows creates a HUGE file over time, which is a database of all of the updates it has done.
The one on my current Windows VM I run on top of my Linux desktop is just over 1GB in size now, which is a large amount for virtual hard drive of only 100GB in size to begin with!
This file is usually located at C:\Windows\SoftwareDistribution\DataStore and is named DataStore.edb.

In order to delete this file to free up the drive space it was hogging, you first need to stop the Update service,
and then just delete the contents of the DataStore folder.
Additionally you should also delete the contents of the Download folder, located at C:\Windows\SoftwareDistribution\Download,
which should free up a lot more drive space!

Then restart the service and run Windows updates again. The file should then get recreated, but it will be a lot smaller to star with, but will grow over time as the previous one had.
