what is the software that can recover all lost data

[mizzsuzanne]

is it possible to recover all deleted pictures in sd card since the first time we use it? or it has specific volume of siz

No, that is not possible.

Some applications may have better or worse success retrieving recently (yesterday) deleted files. But all of them, forever? Not possible.

no, and yes, and maybe. your SD card is probably formatted as a FAT32 file system. Files deleted can be 'undeleted' until they are overwritten. Once the space is used again the files are obviously destroyed. View the format of the SD card and if it is a FAT format look for any DOS undelete utility.

if it is an NTFS or other I've never spent time trying to recover from those as, I'm surprised to say this I've never lost anything by deletion that I needed to recover in quite some time.

Backups are more than just your friend.
