Creates a copy of an existing Library file identified by libraryContentId into the destination folder specified by parentFolderId in the request body. The copied file inherits the source file's metadata including name, format, owners, experts, properties, and profile assignments. The copy receives a new id and versionId and its audit timestamps (createdAt, modifiedAt) reflect the time of the copy operation.

Use this endpoint when an integration needs to duplicate a file into a different folder within the same teamsite — for example, when provisioning content into locale-specific folders or when creating a working copy of a file before making modifications.

The parentFolderId in the request body is required and must reference an existing folder in the same teamsite. Use root to copy the file into the top-level folder of the teamsite.
