# Create Lists
This chapter lists the workflows and how the files of the List function are handled in a Collaboration (BIM360 / **A**utodesk **C**onstruction **C**loud) environment.
Configurations Files of the List function
These are the files used by the List function
1. **LegendConfiguration.Collection.xml** The \[PROJCTFOLDER]\ACPlantTools\PlantExpressTools\ListConfigurations\LegendConfiguration.Collection.xml holds a list of available List Configuration files in the project.
2. \***.lgdcf files** The \[PROJCTFOLDER]\ACPlantTools\PlantExpressTools\ListConfigurations\*.lgdcf files are the configuration files of the List function in your project.
3. **Related Files** The related files are drawing files which can contain a block or the drawing is the block itself. 
4. **Files in Project Manager** 
Opening/Downloading an existing Collaboration project
This is handled if the project doesn't exist in the work folder yet and everything needs to be downloaded from scratch.
1. LegendConfiguration.Collection.xml => DOWNLOADED
2. \*.lgdcf files => DOWNLOADED
3. Related files => DOWNLOADED
Sharing an existing project (which is already setup for Calculation) to ACC
When sharing a project with List Configuration files the following files are handled:
1. LegendConfiguration.Collection.xml => CHECKED IN
2. \*.lgdcf files => CHECKED IN
3. Related files => CHECKED IN
Opening Main Dialog
If you open the Main Dialog of List function the following files are handled:
1. LegendConfiguration.Collection.xml => CHECKED OUT
Closing Main Dialog
If you close the Main Dialog of List function the following files are handled:
1. LegendConfiguration.Collection.xml => CHECKED IN Deleted \*.lgdcf files will be removed from the LegendConfiguration.Collection.xml. Added or imported \*.lgdcf files will be added to the LegendConfiguration.Collection.xml.
Deleting a List Configuration
If you delete a List Configuration the following files are handled:
1. \*.lgdcf file => DELETED This includes the removal of the \*.lgdcf file from the work folder as well as the removal on BIM360.
Creating a new List Configuration
If you add a new List Configuration the following files are handled:
1. \*.lgdcf file => CHECKED IN
2. Related files => CHECKED IN
Editing an existing List Configuration
If you edit a List Configuration the following files are handled:
1. \*.lgdcf file => CHECKED OUT
Closing Wizard
If you edit a List Configuration the following files are handled:
1. \*.lgdcf file => CHECKED IN
Importing List Configuration
If you import a List Configuration the following files are handled:
This is how you do this:
1. \*.lgdcf => Copied to the project => CHECKED IN
Edit a List Configuration without using Wizard
Sometimes it is more convenient to adapt the configuration directly in the \*.lgdcf file without using the Wizard.
This is how you do this:
1. Open your collaboration project in AutoCAD Plant 3D
2. Open the List function Main Dialog
3. Select the configuration you want to modify
4. Click on the **Edit** button to open the Wizard This checks out the \*.lgdcf file.
5. Click on **Cancel** to close the Wizard The \*.lgdcf file will still be checked out. Do not close the Main Dialog yet.
6. Open the \*.lgdcf file under \[PROJECTFOLDER]\ACPlantTools\PlantExpressTools\ListConfigurations in a text editor
7. Make your modifications in the file and save and close it
8. Click on **Refresh** in the Main Dialog This will read the \*.lgdcf file again so you see if there are any error in the file.
9. Close the Main Dialog This checks in the \*.lgdcf file.
