Hash My Files is an application that lets you calculate the MD5/SHA1 hash code of any file you indicate in your PC. This "hash" is a code that works to check if the file has any error, is corrupted or on the contrary has no problems at all.
Hash My Files lets you directly copy the MD5/SHA1 hash code of any file (or a list of them) to the clipboard, or save them in a text or HTML file.
You can run Hash My Files directly from the Windows explorer contextual menu (right mouse button), and show the MD5/SHA1 hash code of the selected file or folder.
