windows - Deleted file recovery program using C C++ -


i want write program can recover deleted files hard drive ( fat32/ntfs partition windows). don't know start from. should starting point of this? should read pursue this? required. system level structs should study?

it's entirely matter of filesystem layout, how "file" looks on disk, , remains when file deleted. such, pretty need understand filesystem spec (for each , every filesystem want support), , how direct block-level access hd data. might possible reuse code existing filesystem drivers, need modified process structures that, point of view of filesystem, gone.
