Win32 Disk Imager is an open-source tool designed primarily for creating exact copies of removable storage media like USB drives and SD cards. It enables users to create disk images (ISO files) from removable storage devices and write disk images to these devices. It is widely used for tasks such as creating bootable USB drives, backing up data from SD cards, and duplicating operating system images.

If you’re regularly running software or games from discs, such as DVDs or CDs, then you’ll probably want to create backups for many of your IMG files. One compact application which lets you do this is called Win32 Disk Imager. Basically, the portable app lets you generate image files from the media content on a USB drive, SD memory card, or another type of removable storage device. Once the information from the device is backed up, it can be restored later.

Simple Interface and Functionality

If you’re a minimalist, then you’ll love the interface of this application because it is very simple to use. There is just one window which you use to add image files, choose the appropriate drive, and then create a hash. As you create your backup or copy of the files, there is a progress bar on the bottom area of the interface which lets you see its operation status. Easily and free download Win32 Disk Imager Portable from FileHorse.com now!

SHA-1 and MD5 hash algorithms can be created, stored, and utilized at times when you must determine the validity of your previously created images. Meanwhile, this information is useful for backing up numerous USB devices of similar size. That way, you won’t restore an image that is different, nor will it be copied to the clipboard to be used somewhere else.

Great for Creating IMG File Copies and Backups

There are advantages to generating copy images of your DVD or game collection. For one thing, mounted images can be run more quickly in comparison to running them off the original discs. Plus, using the discs causes wear and tear to them. You can preserve the discs more by running the images instead.

If creating copies or backups of your favorite movies or games sounds intriguing, then you’ll want to get your hands on the Win32 Disk Imager.

What's new in this version:

New Features:
- Verify Image: Now you can verify an image file with a device. This compares the image file to the device, not the device to the image file (i.e. if you write a 2G image file to an 8G device, it will only read 2G of the device for comparison)
- Additional checksums: Added SHA1 and SHA256 checksums
- Read Only Allocated Partitions: Option to read only to the end of the defined partition(s). Ex: Write a 2G image to a 32G device, reading it to a new file will only read to the end of the defined partition (2G)
- Save last opened folder: The program will now store the last used folder in the Windows registry and default to it on next execution
- Additional language translations (thanks to devoted users for contributing)
