If there are Cue Sheets with identical names, the Cue Sheet which was last built will overwrite the others.
Cue Sheets which have the same name between Work Units will also be overwritten.

Prevent overwrite

The following methods can be used to prevent overwriting the CueSheet.

Using different names for the CueSheets

Although using the same Cue Sheet name is allowed, to prevent the binary data from being overwritten when building,
you can rename the CueSheet name (acb name).

Separating the Cue Sheet hierarchy by Cue Sheet folder.

Create a Cue Sheet folder and give it a unique name (e.g. Work Unit name, version name, etc.)
By moving the Cue Sheet into this folder,
the Cue Sheet is generated to this folder when building, preventing it from overwriting other files or being overwritten.
