lets say you mistakenly deleted a file or formatted a disk or the disk got corrupted and request that you format it. here is a simple solution.
1st download RECUVA in the attachment below
install and run the program
select the type of files to recover [eg pictures or all files etc]
select NO, recover direct from my drive
select the file location. in my case i selected "in a specific location"
click on START. and allow the program to search for the files.
once done. tick the box beside the file you wish to recover then click on RECOVER.
