A few months ago,i re-hashed several Excel files that i'd created,mostly to do with on-line banking & billing,none of these contained info.useable by anybody. I copied much of the old files onto the new ones & then used 'File Shredder' to shred the old files.I ran 'Recuva' to see what it could
recover,& there were the file names of all the Excel files that i'd 'Shredded'. Ok,that's fine,the info. within the fies was gone - period !,but suppose one of the files was called 'My £ million bank account' ( i wish !),then the very fact that the file name remains,would indicate to a 'person' that i did indeed have a £ million bank account,something that i'd maybe wish to keep to myself.
I did contact Piriform over this & they recommended that i run CCleaner's driver wiper using the Gutman process, to wipe the free space on the drive where the files had been kept. I did this a couple of days ago.It took close to 6 hours to run the driver wiper & at the end of it i ran Recuva to see if anything remained. Of the 6 Excel file names,5 had been wiped,but one still remained - how can that happen ??. The file location is given simply as H:\.....
Personally, i feel that if all the information inc.file names isn't going to be 'wiped',then we should at least be given a file 're-name' function within 'Recuva'. It's the only criticism that i have of the Piriform software that i use,that 'private' info.can still remain after a supposedly 'secure' deletion.
