I know nothing about this product, but if it is, in fact, recovering raw data then some of the things recovered (if recoverable) should be the directories. If that is not the case, and you have recovered to a separate drive and not overwritten the original drive, I recommend getting LSoft Technologies’ Active File Recovery. The free version is quite limited, but the professional version is not too expensive, and does a good job of recovering.
I had recent experience with a few recovery products. At least one did not recovery directories. Since I had hundreds of subdirectories and something like 45,000 files, a flat recovery of just files was worthless. Luckily, I was recovering to a different disk so I had lost nothing and was able to try other products. LSoft Technologies’ Active File Recovery did a good job of recovering the old directory structure. Several large (and important) files had been corrupted by the time I did the recovery, but that can’t be blamed on the tool.
