Nodejs: restore a deleted file with fs.unlink

Question

Is possible to restore files that has been removed with fs.unlink() or fs.unlinkSync()?

Answer 1

unlink is a system call in linux, the name comes from there. It deletes the file/folder entry or link from filesystem. It does not wipe out the file.

So is it possible to restore such files ? Yes. It is possible, but

Can you guranatee restoration ? No. The space occupied by file is released back to the system. So it can be written over by other processes.

Should you expect restoration ? No. It was not supposed to provide recycle bin like functionality. It is a low level method for programs to access filesystem.
