Notes about the PRJZIP 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 PRJZIP file type is primarily associated with 'Maestro' by Schrödinger, LLC. Maestro is an all-purpose molecular modeling environment and the unified interface for all Schrödinger software. PRJZIP files are zipped versions of Maestro .PRJ projects. PRJZIP files can be opened directly with Maestro and are opened as temporary scratch projects. Once they are closed, any changes are discarded. Effectively this makes the .PRJZIP file read-only. Use the SaveAs command to save any changes to a project to a new file.
