# ownCloud 7 Server Administration Manual

# Files Locking App Configuration

The Files Locking application enables ownCloud to lock files while reading or writing to and from backend storage. The purpose of the app is to avoid file corruption during normal operation. Operating at a very low level in ownCloud, this application requests and respects file system locks. For example, when ownCloud is writing an uploaded file to the server, ownCloud requests a write lock. If the underlying storage supports locking, ownCloud will request and maintain an exclusive write lock for the duration of this write operation. When completed, ownCloud will then release the lock through the filesystem. If the file system does not support locking, there is no need to enable this application as any lock requested by ownCloud will not be honored in the underlying filesystem.

The Files Locking app has no configuration options; all you need to do is enable or disable it on your Apps page.
