The Lumion Library folder in the 'Documents' folder is taking up a lot of space and slowing down the loading of the Imported Model Library.

You would like to know if the \Lumion[version]\Library folders can be frequently purged without affecting the links to Imported Models in other Projects.

You can remove Imported Models that are part of any current Projects - provided that you do not need to re-use those models in the Imported Model Library browser in Lumion.

1. Here's how using the Lumion interface: 

1.1: You can remove files for the Imported Models via the Lumion Imported Model interface by clicking on the Delete model button (Bin icon).  

1.2: Note that the model you remove cannot be present in the Project you currently have open. Lumion will check and prevent any deletion if that is the case so you do not accidentally remove one. It is best to simply use an empty Project template such as the New Plain Project, and then scan through the Library for models to remove.

1.3: After the model is deleted:

It is not possible to restore the model via the interface, nor via Windows Recycle Bin. It is permanently removed.

1.4: Imported Models are saved in the .LS Project files and then copied and saved to the Library folder when you open a Project.   Opening a Project will have the most current model state. It is more useful to purge old Projects where the .LS Project file will not be opened any time soon. But that is optional and you may want to get rid of more current models as well, which is OK.

​The exception to removing models is when you have Imported Models that are part of your common library and you want to keep those in the Imported Model Library for use in other Projects.

2. Here's how using Windows File Explorer: 

Alternatively, you can delete the four files for an Imported Model using Windows File Explorer.  However, working via the Imported Model Library interface lets you see which model you are considering for deletion.  See the following article.
