Recovering deleted data from Linux file systems
File systems are used to control how data is written to disk, to control access to this data, and to store information and metadata about files. File systems are continually being reviewed to provide more functionality and are becoming more efficient each time.
If you have a curious mind and like experimenting with an alternative OS, don’t do it on your main computer. Not unless you know exactly what you’re doing, have a recent backup handy and know exactly what to do in order to restore that backup. But better yet, try using a different computer to play with alternative systems as you may lose some or all information stored on that PC.
