In smaller environments with only a few user accounts, like which makes question may seem rather strange. The relevant contact persons are usually known personally. In large file systems with thousands of Users however, this is only in exceptional cases the case. If you don't want to ask yourself literally for each directory, you have to try to determine possible data owners by evaluating the file system and the active directory.
This is practically impossible with Windows on-board resources in grown structures create. migRaven.24/7 solves the problem by scanning the NTFS file owners and providing an overview of who created how many files in a directory. The user who created the most files is either the data owner of the directory or knows the data owner. In the next step you can migRaven.24/7 Webinterface simply assign the data owner rights to the identified file owner.
From this point on, the data owner can become active himself and decide that, for example, certain directories can be archived obsolete and ad hoc, authorizations must be adapted or archiving policies should be assigned to specific directories.
