Two possibilities:

1. You are using that command in the same location of the file.
--> It is a possibly a typo.  You can use tab completion to help ensure
the right file is found in the current directory.

2. You are using that command in a location other than that of the
target file.
--> Make sure that you are in the same directory of your target file.

Look for your mounted media under /media/ and cd to the appropriate
location before using the command.

From https://help.ubuntu.com/community/Mount/USB:
----------------
Mounting
By default, storage devices that are plugged into the system mount
automatically in the /media directory, open a file browser window
for each volume and place an icon on your desktop. If you plug in a usb
hard disk with many partitions, all of the partitions will automatically
mount. This behaviour may not be what you want so you can configure it
as shown below.

If the volumes have labels the icons will be named accordingly,
otherwise they will be named "disk" and as more volumes are added, you
can get "disk-1" and so on.

Hope this helps!
