unzip

Things like this, my friend send me a package named qcon.zip with his Mac pc. I use ubuntu system,when I use the command to unzip the folder,I found something was wrong.I check the permission,and use another soft named 7z,but it can't work now.

when i use the command
unzip qcon.zip

unzip qcon.zip -d test/

it returns me that:

unzip: cannot find or open ”-O, ”-O.zip or ”-O.ZIP.

So after install 7z,the command I use ,

Error: qcon.zip: Can not open file as archive

--add the command file---

file qcon.zip

it returns
qcon.zip: Zip archive data, at least v1.0 to extract

So,what can I do now,the folder permission is right.
