Whenever you download a file from the Web with your browser, using an FTP client or get files as e-mail attachments the software may store additional information about the origin of the files. This information may contain the source URL of the file. In the case of an e-mail attachment it can contain the e-mail address of the sender and the subject. With AVT WhereFrom you can view this information and remove it if needed. Important Note: Not all browsers, e-mail or FTP clients do save this information.
