Disk Image


Disk Image is a copy of your logical drive or physical device that is stored in one file. This can be useful when you want to backup the contents of the whole drive, and restore it or work with it later. Before you start recovering the deleted files, it may be a good idea to create a Disk Image for this drive, if you have enough space at another drive. Why? Because if you do something wrong while recovering the files (for example, recovering them onto the same drive could destroy their contents), you still will be able to recover these deleted files and folders from the Disk Image that you have wisely created.

Active@ UNDELETE provides extensive functionality to operate with Disk Images. You can create image of either Logical disk, Device or Partition. Save it as one large file or split on image chunks with size you prefer for later use.

When you creating Disk Image, it stores in at least two files: one is Configuration file with file extension .DIM and the second - actual image body file. If you decide to save disk image chopped on peaces (chunks) then image body files can be as many as its required to save data.

Here is an example: If you save a raw disk image with the name MyImage, the application creates a file named MyImage.dim. This is the configuration file. Data is stored in a file named MyImage.dim.001. If more than one file is created, the next file is named MyImage.dim.002, and so on. The data file can be split in several files – chunks that can be useful if you want to save the Disk Image on a CD or Data DVD.

Create Disk Image

  1. Start Active@ UNDELETE and select the drive, device or partition you want to create an image.
  2. Run the Create Disk Image wizard by doing one of the following:
  • Click the Create Disk Image button on the toolbar, or
  • Click Tools > Create Disk Image in command toolbar, or
  • Right-click the selected drive, and click Create Disk Image on the context menu
  1. Follow the instruction of this wizard

Configuration file for Disk Images has .DIM extension by default.

  • The Target Location for the drive images must always be on other drive.
  • File systems FAT16 and FAT32 do not support file sizes larger than 2GB and 4GB respectively. In these file systems is not possible to create a disk image file for a drive as it is likely to grow larger than 2GB (or 4GB). The solution in this case is to use a target location formatted under the operating system Windows NT/2000/XP and NTFS or create Disk Image split in chunks by appropriate size.
