When you delete files, you don't really remove the data. DOS simply marks the area as available for overwriting by new data. Sometimes this is useful - the "Undelete" program exploits this to allow you to recover accidentally deleted files. On other occasions, this is a security risk - you want to prevent people recovering confidential data.
This program stops people recovering the data. It wipes all the unused disk area with random data. This technique provides "after the fact" protection. Imagine putting all your old confidential documents in a trash can. "Washer" shreds all the documents in the trash.
