Base64 Decoder is a Free and Portable Tool created by Tim Rohlfs. It can be used to decode attachments found in email files. For example, I used it as a Windows Live Mail Attachment Extractor to decode Windows Live Mail .eml email files, and save or extract those Base 64 encoded email attachments to another location.
