* transaction. So, there may be a file/directory on disk, but which was deleted (virtually)
* by the current transaction. Such a file/directory is non-existing for the current transaction.
* Similarly, a file/directory which is not on disk, but which was created by the current transaction,
* is existing from the perspective of the current transaction.
