// 1. Detects user drop position and on ambiguity asks user if replace current link.
// 2. Detects if user provided file's valid path (in Documentation/Source hierarchy)
// exists. If it does, then asks user if the file should be overwritten and copy
// the file as needed.
// 3. Replaces or appends a valid link.
