UndoSpace

Description

Gets and Sets the maximum amount of disk space, in bytes, available for undo checkpoints.

Every time an editing operation is performed an undo checkpoint is created to enable rollback of that operation. If the total disk space used by these undo checkpoints exceeds the value specified by UndoSpace, no more checkpoints are created. Previously created checkpoints still exist.

When the file is saved, all checkpoints are discarded, reducing the space they occupy to zero.

Syntax

[C#/C++]
public Long UndoSpace;

[VB.NET]
Public Property UndoSpace As Integer
