Default Value



This property specifies whether the operating system's cache should be used. Use of the OS cache affects the speed of various vault operations; however, note that the exact effects depend on the type of operation as well as the data sizes involved.

Disabling this property will cause a vault's storage file (specified by the VaultFile property) to be opened with FILE_FLAG_NO_BUFFERING (on Windows) or F_NOCACHE (on Linux/macOS).

Note: This property cannot be changed when Active is true, and cannot be changed within events.
