NSURLMBS.NSURLVolumeAvailableCapacityForOpportunisticUsageKey as string
Type Topic Plugin Version macOS Windows Linux iOS Targets
shared method Cocoa Networking MBS MacBase Plugin 21.2 ✅ Yes ❌ No ❌ No ✅ Yes All
Function: One of the file system URL resource keys.
Notes:
Total available capacity in bytes for "Important" resources, including space expected to be cleared by purging non-essential and cached resources. "Important" means something that the user or application clearly expects to be present on the local system, but is ultimately replaceable. This would include items that the user has explicitly requested via the UI, and resources that an application requires in order to provide functionality.

Examples: A video that the user has explicitly requested to watch but has not yet finished watching or an audio file that the user has requested to download.

This value should not be used in determining if there is room for an irreplaceable resource. In the case of irreplaceable resources, always attempt to save the resource regardless of available capacity and handle failure as gracefully as possible.

Value is zero if unknown. Please switch to NSURLVolumeAvailableCapacityKey key in that case.

Read-only, value type number
