I suspect your file is not lost, it has just been moved to the root directory and renamed to Home.
You should find a file in your root directory called Home. This will be your file.
Why this happened
The filesystem in unix/Linux is case-sensitive, meaning that home and Home do not refer to the same thing. While you probably intended to move it into a directory called home, you used a capital H, so it did not find such a directory and instead interpreted your command as a request to move it and rename it to a new file called Home.
Solution
Always use the correct case. You could also have prevented this happening by adding a trailing slash after the directory name, eg.
mv file.7z /Home/
This would cause it to look for Home as a directory. If it didn't find such a directory, then instead of renaming it to Home as a file, it would have failed.
Mvormv?/Homeor/home? Capitalization matters. Probably you should look for a file calledHomein the/directory. – steeldriver Oct 25 '16 at 00:50
