Using Photorec for recovering Photos/MP3/Videos/ Office files

Install Test Disk from Synaptic package Manager.
open terminal then
$ sudo photorec
You will asked to choose HD drive fromwhere files are to be recovered

While using Photorec there is an option for file types to be recorved.
For recovering photos use JPEG file option and disable all other file types.(for recovering MP3 files choose MP3 option and disable all other filetypes)
With this the size of recup directories (in Home folder) will be manageble and home folder will still have memory left.
Creat a new folder - Name it as Photo-rec.
Open folder of recup_dir-1 as a root.
Copy all files from this folder to newly created folder Photo-rec.
open all the folders recup_dir one after another as a root and copy files to newly created folder Photo-rec.
Now you can delet all recup_dir folders,since all recovered photos are in newly created folder Photo-rec.
Install Shotwell from Synaptic or Software Center.
Open Shotwell.Import photos from Photo-rec.While imporing from folder use copy option.
Shotwell will import and make albums in Picture folder.The albums are created Yearwise,having subfolders monthwise and datewise.Shotwell does not import duplicate photos.
The sorting is done in minutes.
Images from web are sored in a seperate folder havig year as 1997 or1998 (earlier year that of Jpeg images recovered of Camera Photos.
I had recently recovered around 16000 photos.
Shotwell had sorted the photos within 10 minitues.
