Frequently Asked Questions

1. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

2. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.
