Recovery software for .rar files

HI all. I am looking for a FREE (at least as a time limited demo) recovery software that will enable me to find and recover a few deleted .rar files.
Most standard once cant seam to handle that, for example Pandora recovery only sees the files and thinks they are in a corrupted folder but the files are 0% corrupted, so it recovers it. BUT the recovered file is unusable, since it was in fact in a rar file.

The software recovermyfiles seams to find them with the proper address and seams to be searching rather in detail, but it is not free and to actually save a file its required to buy it, which is pretty steep at 70$.

So does anyone know of a few good and thorough recovery software that can handle archived .rar files
