CLI

exfs can also be controlled via the command-line. On Windows, you need to be an admin user in order to mount drives.

 $ exfs --help 

ExpanDrive 7.5.2
Usage:
ExpanDrive [OPTION...]

--help                  Print help

--foreground            Keep exfs in the foreground
--sync                  Enable sync write operations
--register license_key  Install license key

Most options are self explanatory, except perhaps sync. Since exfs runs unattended, it is not always desirable to have filesystem operations complete in the background, since if there is an error condition there is no good way to report it to the user.

The sync option makes it such that operations like delete, rename, and write don't complete until they've been propagated out to remote storage.

This can often be what is necessary for an application, but is generally much slower since there is no opportunity to aggregate and parallelize multiple requests.
