Well, this is a mess. I use a NTFS partition for my files and if I open
Trash I have 3 differents icons for the same program.
Files, or Nautilus, it's one program and should work like any other
program. 1 icon for each program instead of 1 icon for each windows of the
same program.

Title:
  After minimizing a Nautilus window of another partition or external
  media or Trash folder, clicking on the "Files" icon on the Launcher
  again doesn't restore the minimized window, but opens a new one

  Triaged
Status in Unity:
  In Progress
Status in unity package in Ubuntu:
  Fix Released
Status in unity source package in Trusty:
  Confirmed

Bug description:
  *******
   ISSUE
  *******

  HOW TO REPRODUCE

  1. Connect a removable media to the computer.
  2. On the launcher, click on the "Files" icon.
  3. On the left sidebar, click on the removable media icon or the trash.
  4. Minimize the window.
  5. Click on the "Files" icon.

  EXPECTED BEHAVIOUR

  - The Files window to be maximized.

  REAL BEHAVIOUR

  - A new window is opened.

  RELEVANT DETAILS

  - One way to navigate between windows at this moment is to use the
  "control + tabulation" key combination, or to click again on the
  "Files" icon so windows are exposed.

  Otherwise the minimized window Can be restored by clicking on the
  Volume's launcher icon or scrolling on the Files icon

  **********
   SOLUTION
  **********

  WORK-AROUND

  - On the launcher, left click on the "Files" icon and select the
  "unlock from Launcher" option.

  - Or hover the mouse over the Nautilus icon in the launcher, and roll
  the mouse wheel down/up, it should switch to the Naulitus window
  without open new instance of it.

  FIX

  - The launcher icon for "Files" to be treated the same way as if it
  was unlocked.

  REGRESSION POTENTIAL

  - Clicking on the "Files" icon won't send the user to its home folder,
  but to the latest opened Files window.
