FYI, Deleted data is only recoverable til overwritten!!!
And since you’ve deleted it from the OS partition, It’s highly susceptible to overwrites, Especially from temporary files and browser cache. For this reason, You should turn off your computer in order to prevent partial/complete overwrite of the data in question. You should do the following:
1. From another computer, Download the bootable version of data recovery wizard
http://www.2baksa.net/news/91325/
Use the sendfile.su link (After clicking it, You’d see two blue buttons, Click the one on the left to generate a direct link underneath it, The rest is fairly obvious.)
2. Extract it, Install and create a boot cd/flash drive.
3. Use the boot cd/flash drive you created on the other computer (Where the data loss has occurred)
Since it’s bootable, You have to run it before the OS. Meaning you’ll need to enter the BIOS and define the boot device priority accordingly. Also, Disable secure boot if you have that option.
4. After booting, DRW would automatically start. It’s pretty simple to use, So I’m not gonna provide any explanation on that.
But again, Do remember that from reasons I already mentioned you DO NOT wanna recover the data into the same partition it was deleted from! you’re gonna have to recover it to another partition, or external hard drive.
Good luck. Better be more careful next time!
Also, You might wanna consider keeping backup from now on.
Most people take their data for granted til a disaster strikes, Which is quite unfortunate!

there are other programs to recover your files while you’ve got your computer turned on too, in case your uncomfortable with doing a recover from a bootable cd/usb
try recuva, it’s made by a company called piriform and I’ve had pretty good success with it myself.
Roberto gave you the best/safest option you could possibly do, but if your uncomfortable with it, try recuva
