Some measures you need do after lost files:
1. Please don’t save any new data or files to the drive where you lost files, as the new files will overwrite the lost files, this maybe increase the difficulty of data recovery, or make the files become unrecoverable.
2. When you lost files from USB sticks, Memory cards, or other similar devices, get them off the device and perform data recovery immediately. As digital camera and mobile phones, power them off before taking the card out.
