Making Content Available for Offline Use.In addition, if a cached file has a new version created on Box, Box Drive discards the locally cached version. If you reach this limit, Box Drive begins removing files, starting with those files that have gone the longest without opening them. Box Drive's cache size limit is based on your free disk space (50% of available space) and has a maximum limit of 25 GB. NOTE: Box Drive does locally cache files that you have opened. Box Drive synchronizes the versions as soon as you go back online. Box Drive also supports making files available offline, so you can work on them while disconnected from the Internet. Box Drive shows the exact same content as is seen in Box Web App. Box Drive brings your entire Box folder tree as a virtual drive to your File Explorer, whether this content is owned or shared.
