The portable version, in the PortableApps format, is now current with the main or regular release. PortableApps will run anywhere, locally or in the cloud, and do not make or rely on changes to Windows. Besides the impact of installing the full version LibreOffice, I like the option of just starting whichever app in the suite that you want. The single file download is an installer that puts everything in a LibreOffice folder that takes up 609MB with 13591 files, 1209 folders.
