You can download programs such as...File Recover or Uneraser which can recover deleted files. When a file is deleted from the recycle bin, the data can still be recovered unless new files added to that drive have overwritten the data. Files deleted from the recycle bin remain hidden on the drive until other data needs that space on the drive.
Don't install any type of data onto the drive that the 'lost' files were on. Try to download one of the programs onto a different drive and run from there. You might have a chance of recovering the data if nothing has overwritten it.
