IsolatedStorage.AvailableFreeSpace Property

When overridden in a derived class, gets the available free space for isolated storage, in bytes.

Namespace:  System.IO.IsolatedStorage
Assembly:  mscorlib (in mscorlib.dll)

public virtual long AvailableFreeSpace { get; }

Property Value

Type: System.Int64
The available free space for isolated storage, in bytes.


An operation was performed that requires access to AvailableFreeSpace, but that property is not defined for this store. Stores that are obtained by using enumerations do not have a well-defined AvailableFreeSpace property, because partial evidence is used to open the store.

The IsolatedStorageFile.AvailableFreeSpace property overrides this property.
