The code is resposing well, but it is usefull for file shreding, it uses WriteFile() to overwrite on the file.
For shredding a folder I must search the space of the folder & iterate this procedure for all files, and about the subfolder we need a recursive code to traverse them.
Is there any better solution to wipe a folder of shred a whole drive?
I thinked that the files of the folder could be deleted in this way and finally the empty folder that is not important can be deleted from the system instructions.
This idea is feasible, but the only concern is about the complexity for the huge folders with various subfolders; it is time consuming.
