Download will not open

I have my mobile connected to a laptop and have accidentally deleted a whole file of photos off the phone via the laptop. On my mobile, I have gone to the ccleaner website and clicked the download link to get the free recuva (I have done this 3 times I think now) and each time it seems to download, no problem. The page says "Thank you for downloading Recuva" and a little notification pops up on my phone saying "download successful". However, whenever I tap this it takes me somewhere on my phone that says 'Archive preview' in the background and in the forefront there is a Note saying 'Unable to open', with the only option being to press OK.

Have I done something wrong? I'm not very "computer savvy" and really have no clue what I'm doing!

Please, please help!

Much thanks,

TiredandDesperate (and on the edge!)

If you are downloading and opening Recuva on your mobile phone, your phone will not know what to do with it. You need to download and run it on your PC.
