Notes about the MASS file extension:



To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The MASS file type is primarily associated with 'Mass Downloader' by MetaProducts Corporation. Mass Downloader (MD) is a Windows program that allows you to download individual files (or lists of files) from Web and FTP sites at the maximum available speed. Multiple channel technology reduces download time. MD also allows you to browse ZIP archives before loading them and to choose only the desired file(s) to download. Downloads get the .MASS extension while downloading and it is removed when the download is complete.
