When disk space is low the Nextcloud Client will be unable to synchronize all files. This section describes its behavior in a low disk space situation as well as the options that influence it.

1. Synchronization of a folder aborts entirely if the remaining disk space falls below 512 MB. This threshold can be adjusted with the ``OWNCLOUD_CRITICAL_FREE_SPACE_BYTES`` environment variable.

2. Downloads that would reduce the free disk space below 1 GB will be skipped or aborted. The download will be retried regularly and other synchronization is unaffected. This threshold can be adjusted with the ``OWNCLOUD_FREE_SPACE_BYTES`` environment variable.
