Project members with the Document Admin permission can copy and move documents.
They can also create and administer documents.
However, they
can delete documents, only if they have the specific delete
permission.
Copy a document
If a given document belongs logically to two or more document folders, keeping a copy in each folder can help users locate it.
Move a document
You can move it to another document folder within the project or to a document folder in another project at any time. This allows you to reorganize documents as needed.
Delete a document
If you no longer need a document, you can delete it.
