Encourage you to read other reviews of this company before paying for their software. Demo version indicated my file could be recovered so I upgraded to the paid version, but the file could not be recovered. I contacted support and noted it was showing file size as 0kb. (I later found out this is due to a NTFS limit on files >4GB that diskinternals can't handle). Support offered to assist me in recovering a 0kb (empty) file with the same name as my deleted (not empty) file. When I asked for a refund I was rebuffed and they insisted that creating a 0kb file with the same name as my deleted file constituted 'recovery'. When I mentioned I might post this review they threatened me with legal action.
