Recovering from USB/Hard Disk:

  • After copying the device path, now we have to recover the files from that device.

Use the options available by the “foremost -h” command.

For example

foremost -t jpg,pdf,mp4,exe -v -q -i /dev/sdb2 -o /root/desktop/recover

  • -q: It is a quick scan for the device
