With the free software CompareChecksum you can calculate checksums of any files on your harddisk, without effort. Calculation starts automatically, if you select a file per dialog or if you drag and drop a file on the software-window. Even more simple is it to start CompareChecksum by clicking with the right mousebutton on on file and using the "Send to"-option.
By comparing the checksums of two files, you can determine, that
a download via internet was not corrupted. At the same time
you can check if the file was possibly targetted by a manipulation.
Besides, you can control, if pictures or documents with different names, have identical content.
You can download an istallation wizard that generates automatic
shortcuts in your Start Menu folder, on your Desktop and in the Send To folder,
if you like. Besides there will be an uninstaller, that enables you to remove all
components of CompareChecksum after useage.
You can also extract the files of CompareChecksum by hand. CompareChecksum runs without installation, so it is perfect for portable and mobile use on a USB-device.
