Disable Undo/Redo

Ctrl+U

Edit Menu

From the Edit menu, choose Disable Undo/Redo to prevent Sound Forge from creating temporary files used for undoing operations. Since creating undo files takes time and disk space, it is sometimes more convenient to have the Disable Undo command selected when working with large files.

Remember to turn the Disable Undo command off when you wish to be able to undo operations.

Since Sound Forge doesn’t modify the original file unless the file is opened in direct or read-only mode, you can always recover it by reopening the file. However, saved changes are permanent.
