To actually recover the documents, you need an account with Hetman Office Recovery, which you can open on their official website. Without an account you can only see the files in miniature. Even so, you can still get an idea of whether you can recover the information you lost.
Hetman Office Recovery is a great file recovery tool for use with a damaged memory card or hard drives where you had files you deleted.
The program supports the most popular formats such as DOC, DOCX, DOT, XLS, XLSX, ODT, ODS, PDF, PDB, RTF, WPD, and WRI, among many others.
The demo version only shows files that can be recovered with the complete version.
