Notes about the QSPLUGIN 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 QSPLUGIN file type is primarily associated with 'Quicksilver' by Blacktree, Inc.. Quicksilver is a launcher for the Macintosh. Any item you are able to find, drag, or otherwise pull into its universe is endowed with many potential uses. Hitting Tab takes you to the action field, where you can use the same adaptive search to select what you would like to do. Among other things, files can be emailed, copied, compressed. Plug-ins extend the capabilities of Quicksilver.
