Removing Unused Objects

Limitations, when its not safe to remove

This feature only shows the places the object is using directly, not using by an indirect reference or string manipulation. 

Here are some examples where an object is used indirectly:

• Via TagReference using the .Link Property (reason why use the Tag1.GetName() when possible, instead of "Tag1" when setting the value for this property)
• Via AssetPath, using the syntax. Asset("/folder1/tag1")
• Via scripts settings directly TagNames on TrendChart and other objects. 

When is generally safe to remove

For most solutions, the indirect reference it's used only for Tags. They display can be used by strings reference using the Client.OpenDiaplay("stirng") method.

Other objects for other modules, like Datasets, Devices, typically are not used as a reference. 

Therefore, in general, other objects you can remove directly, and Tags or Displays, as long you aren't used the describe indirect access. 

See TrackChanges → CrossReference for example of configuration using indirectly the objects. 

Only remove unused objects, if you're sure they aren't used indirectly or by external applicationsThe reason, the "in general" warning was present, is that using the Toolkit, like the TK.GetObjectValue(), it's possible to indirectly access any object in the application.
