Hi I used CCleaner for the first time about 4 weeks ago to delete (I thought ?) duplicate files from my pc having made backups on external drive and OneDrive but subsequently found they had failed.
When I checked my pc I realised had lost some important Excel files I require for my small business and a significant chunk "Sent" Emails for last 10 months or so, but Inbox emails are all OK ?
When I tried Recuva to recover the deleted files no sign of the Excel files not even references to the file names ?
Some PST files were recovered but not sure how to check these Microsoft Help people were not much use ??
I realise this is a complicated question but any advice or ideas of what to do next welcome
Thanks in advance
