Collect a users orphaned Drive files/folders into a target folder; only orphaned files not in the trash are processed.

gam <UserTypeEntity> collect orphans
        [(targetuserfoldername <DriveFolderName>)|(targetuserfolderid <DriveFolderID>)]
        [useshortcuts [<Boolean>]]
        (orderby <DriveOrderByFieldName> [ascending|descending])*
        [preview [todrive <ToDriveAttribute>*]]

• targetuserfoldername <DriveFileName> - This is the parent folder name for the orphaned files; the default is "#user# orphaned files". In this string, #user# and #email# will be replaced by the source user email address, #username# will be replaced by the source user mail address without the domain. This folder will be created is necessary.
• targetuserfolderid <DriveFolderID> - This is the parent folder ID for the orphaned files; it must exist.
• useshortcuts false - Add the target user folder as the parent of an orphan if it can be done; otherwise, put a shortcut to the orphan into the target user folder. This is the default behavior. Changing the parent may affect the orphan's access by other users.
• useshortcuts or useshortcuts true - Put a shortcut to the orphan into the target user folder and do not modify the orphan's parents. GAM will not duplicate an existing shortcut.
• orderby <DriveOrderByFieldName> [ascending|descending])* - Specify the order in which files are processed.
• preview - If preview is specified, no files are collected; a CSV file listing the files to be collected is output.
• todrive <ToDriveAttribute>* - When preview is specified, the CSV file can be uploaded to Google
