Kahua can manage multiple versions of the same file.  When uploading a file with the same filename, Kahua will prompt the user to create a New Version or Skip and not add a new version.  Once multiple versions are uploaded to Kahua, users have the ability to access all versions, delete specific versions, and make older versions the newest version.

Unlimited numbers of versions can be maintained in Kahua.  Each version however does count towards an account's file space quota.
