Let's say your using Wheezy Linux (applies to everyone running Emulation Station on a Pi 2), and you need to copy files over from a USB stick.
Wheezy, unlike most flavors of Linux, doesn't automatically mount USB devices. It knows it's there, but without doing the following you can't access the contents by standard means.

Step 1: Insert Your USB Stick
I hope this doesn't need explanation.
Step 2:
To see if your device is recognized, go to the command line and type:
sudo lsusb
Look for your devices name in the list.
sudo lsusb
Look for your devices name in the list.
Step 3: Find Where It's Located
If you see your device, type in:
sudo fdisk -l
(That's minus L, not minus 1)
This returns some choppy text, but scan for a section with the text "Disk /dev/sda".
Around here you should see a disk size indicator identical to your USB stick.
Look at the bottom of this section and see where it says "Device Boot".
Under this is a file path. In my case it is "/dev/sda1".
sudo fdisk -l
(That's minus L, not minus 1)

Under this is a file path. In my case it is "/dev/sda1".
Step 4: Make a Mount Directory
If you aren't at the root directory, move there using this:
cd ..
From here, make a directory titled "mnt". Use this:
mkdir mnt
Now, we can mount the USB stick.
To do this, type "mount -t auto" followed by the USB stick's location "/dev/sda1" and the mount location "/mnt".
All together it looks like this:
mount -t auto /dev/sda1 /mnt
If done right you should have access to the directory and be able to see your files.
cd ..
From here, make a directory titled "mnt". Use this:
mkdir mnt
Now, we can mount the USB stick.
To do this, type "mount -t auto" followed by the USB stick's location "/dev/sda1" and the mount location "/mnt".
All together it looks like this:
mount -t auto /dev/sda1 /mnt
If done right you should have access to the directory and be able to see your files.
Step 5: Get Your Stuff
Using the file navigator, I can read the files from the USB stick. Note that people cannot access this from the command line because by default it's set to read only.
You can now copy the files from your USB stick using the "cp" command.
Usage:
cp file1 file2
Example:
cp /mnt/SUPERimportantFILE.txt /home/pi
This moves the text file to the home/pi directory. You also can rename the file by changing it's name in the move-to location.

Step 6: PLEASE READ
If you remove your thumb drive while your system is still on, you CAN corrupt it or a small section of it.
To prevent this, go to the command line and type:
sudo umount /dev/sda1
After this it is safe to remove your thumb drive.
After you reset or unmount your drive, you will have to remount it. Simply just type as before :
mount -t auto /dev/sda1 /mnt
To prevent this, go to the command line and type:
sudo umount /dev/sda1
After this it is safe to remove your thumb drive.
After you reset or unmount your drive, you will have to remount it. Simply just type as before :
mount -t auto /dev/sda1 /mnt
