Every document and folder is owned by either a user or a company. Users who belong to a company (in a Professional or Enterprise subscription) create company-owned documents and folders by default. Users who are not members of a company (that is, users in a Free, Education, or Standard subscription) automatically own the documents and folders they create. For users belonging to more than one paid subscription, a drop down is included in the Create document/folder dialog with which you are able to select the owner at the time of creation.

Keep in mind that ownership can be transferred from one owner to another, and from one company to another. This topic covers that information, and includes a discussion of how transferring ownership can sometimes affect metadata and in particular, release management.

Owners of documents/folders and owners of companies have these permissions on documents/folders they own: Delete, change sharing privileges, make Public, make Private, and Transfer ownership. Ownership may be transferred at any time, by the owner or company admin, through the Transfer ownership dialog:

Transfer ownership dialog

Users who own documents or folders can transfer that ownership to another user, or to a company of which they are a member. In general, when transferring ownership to a user, that transfer recipient must accept the transfer in order for the action to be complete. Be aware there are special cases in addition to this scenario. For company/enterprise-owned documents, only the administrators of the company/enterprise can transfer ownership.
