Free disk image backup software for windows

Disk Usage and Backup Tool displays a graph of your disk space usage per folder Disk Usage and Backup Tool displays a graph of your disk space usage per folder.
It also has a facility for comparing two folders and listing differences, and finally the ability to perform a differential backup of only modified/new files in a folder to a new folder.
There is no compression, but the files remain accessible even without the software tool since the backup is made by file copies.

Disc image application is a driver that can mount ISO CD/DVD images into a Microsoft Windows 2000/XP/2003 based system Disc image application is a driver that can mount ISO CD/DVD images into a Microsoft Windows 2000/XP/2003 based system.
This gives the impression that a new CD/DVD-ROM drive has been added and a disc has been inserted.
The small size of the driver and its simple operation allow an integration which is similar to actually using CD/DVD-ROM hardware, but as the drive is virtual, there is no hardware noise or lag. It is even possible to mount as many images as there are available drive letters.
The Disc image system can mount ISO images that contain either ISO9660 or Joliet (or both) file systems, which on a Windows 2000/XP/2003 based system allows nearly all ISO images to be mounted. It will not allow images to be mounted if Windows does not read that type of file system e.g. HFS+.
For single users the Disc image system allows you to store frequently used CD/DVD images so they can be accessed quickly and quietly (no more loud whirring noises).
It will also eliminate the need to have a disc left in the CD/DVD drive when running applications that require access to the disc.
When using on a laptop, it allows better use of the battery as CD/DVD drives require a large amount of power, especially when the drive is running continuously.
When you create ISO disc images with products such as Nero, the created images can be mounted using the Disc image system, allowing them to be tested before being burned to discs, thus reducing disc wastage.
Main features:
- No CD/DVD swapping.
- Faster access than the quickest CD/DVD drive (nearly as fast as the hard drive that holds the image).
- Small size (it is just a driver after all).
- ISO9660 and Joliet file system compatible.
- Allows access to as many CD/DVDs as you have spare drive letters.
- Because the driver works with the ISO standard it gives you the opportunity to store images that can be accessed by other operating systems such as Macintosh and Unix as they already have the ability to mount ISO images built in.
- Any size of image can be used.
- Option of right-clicking or double-clicking an ISO file to mount it.
- Fully multi-threaded.
Version restrictions:
- Only images below 650MB can be used.
- Includes a mount time limitation, where mounted images become inaccessible after 5 minutes.
- Demo expires after 30 days or 20 edits/mounts, whichever comes first.

Roadkils Disk Image creates and writes disk images files to hard and floppy disks Roadkils Disk Image will create and write disk images files to hard and floppy disks.
Great for writting boot disk images download from the internet or creating a perfect copy of a disk to email to someone else.

Diskwriter gives you a small program to write disk image files to a floppy disk Diskwriter gives you a small program to write disk image files to a floppy disk.
It can be used to write bootdisks for operating systems. Very nice is that this utility works on Windows 95/98/NT4 and 2000. Since the different operating systems use different methods to write to a disk, different methods are implemented. It probably only works for 1.44 MB disks.
