Format memory card option on the menu

Deleting or formatting won't make the data in memory card erased permanently.

Those deleted data is still stored on the memory card, it's just invisible or inaccessible. Only the FAT or NFTS table is erased (the information about where those data were saved), but the real data are still intact there in sectors of the hard drive.

So as long as those data are not overwritten by new data, it's highly possible to recover them. And the MOST Effective way is to rely on some format recovery programs.

Try this data recovery program called asoftech data recovery, which can recover data after deeply scanning your memory card to look for lost data you accidentally deleted or formatted.

Note: before the data is recovered, never attempt to put more files to the USB drive. As saving more files may cause original data overwritten. Once overwritten, it's impossible to recover the lost items.

Good luck and best regards!

The answer is Positive, you have chance to recover the lost memory card files(pictures, videos or music) with so-called photo recovery software but it's not 100% sure. Well, since you failed to mention the OS you are running, I'll recommend you have a try of Wondershare Photo Recovery, a program equipped with both Windows and Mac versions. For Windows OS, download here. If you are running Mac OS X, get the program from this link.

Step-to-Step Instruction:

1. Download and install the trial version on your computer, then connect your camera memory card to the computer (I assume you are using Windows). Start Wondershare Photo Recovery and select the drive letter that assigned to camera memory card.
2. Then choose the file type (all, photo, video, music) click "Star Scan".
3. Now the scanning process will start automatically to look for the deleted items. You will then get a list of all recoverable ones.
4. Preview the photos. If your deleted ones are found, then you need pay to get the activation code. And click "Recover".

Tips:
1. Take the free trial version before you buy.
2. Before your deleted items are recovered, do not take more photos or videos.

I hope you good luck. Greetings

Once FORMAT option has been accidentally selected
on the menu of your camera and there are pictures saved on your memory card, then it will automatically be deleting all the stored images on your card.

It's just really recommended to use the FORMAT option if it's
your first time to be putting the card on the camera.

But, if there are pictures already stored there, try to stay away from that OPTION so that your pictures will not be deleted.

There is no way for pictures to be retrieved.
So. it's advisable as well that you should transfer first your pictures to your PC before you could select on the FORMAT
option of your camera.
