File carving doesn’t care about any file systems which is used for storing files.In the FAT file system for example, when a file is deleted, the file’s directory entry is changed to unallocated space.

What is meant by data carving?

“Data carving is the process of extracting a collection of data from a larger data set. Data carving techniques frequently occur during a digital investigation when the unallocated file system space is analyzed to extract files.
