Name will now be open. Rename the Matter Folder name here, then click Save. The Matter Folder name will now be changed but the Matter name itself will remain the same.
You can add subfolders to these folders either from the cloud storage or the CosmoLex side, and name them whatever you wish.
Also note, that some document storage providers place integration content in a designated area. For example, Dropbox has an “Apps” folder. The CosmoLex folder is created within the Apps folder upon setup. In order for integration/syncing to work properly, the folders must remain in this default location.
