so I'm interpreting this as: you are thinking that the command you ran to try to extract the .tgz file actually tared up all the contents of your home directory into "@LongLink".
Assuming this to be true I have a couple of requests for more information. Please run the following commands in a terminal and cut and past the output into the forum in "[code]" tags (like what I'm using below).
With this information we may be able to help you.
PS. I'm unsure what you mean by "@LongLink", hopefully the output of the above commands will help clarify.
