Import Packages Does Not Work When Project Location Path Is 13 Directories / Folders Deep

Question

Please could anyone tell me why a Unity Project root directory cannot have a path location thirteen directories deep? For example:

C:\Users\Person\Desktop

ext_dir_4
ext_dir_5
ext_dir_6
ext_dir_7
ext_dir_8
ext_dir_9
ext_dir_10
ext_dir_11
ext_dir_12
ext_dir_13

I am following an “external” Unity tutorial and the files provided are in a lot of folders.
I will move the Unity projects to a shorter path name but am puzzled at why I have to stick to a short path name.

A more detailed version of this issue is below.

Unity version

4.3.4

Operating System

Windows 7 (64 bit)

Steps To Get Issue

  1. Unity has just been installed and no projects have been made.
  2. Double click Unity Desktop shortcut
  3. “Unity - Project Wizard” pops up
  4. “Create New Project” tab
  5. Click on the “Browse” button
  6. Navigate to a directory / folder that is thirteen directories deep.

For example:

C:\Users\Person\Desktop

ext_dir_4
ext_dir_5
ext_dir_6
ext_dir_7
ext_dir_8
ext_dir_9
ext_dir_10
ext_dir_11
ext_dir_12
ext_dir_13

  1. In the “Choose location for new project” click on the “Select Folder” button
  2. Unity Project Wizard
  3. “Import the following packages”
  4. Tick “Character Controller.unityPackage”
  5. Click on “Create” button
  6. Unity opens
  7. Project Panel

The Assets folder is empty.
This only happens when the project root path is thirteen or more directories deep.

Thank you for the incredibly quick responses.
This may be a bug and I will report it.
I can now import Unity packages into “next_dir_13”. I am not sure what enabled this but previously I had done the following:

  1. Saved a Unity project in another directory (with a short path name)

  2. Saved a scene in this directory

  3. Saved a Cinema 4D project in

    C:\Users\Person\Desktop
    ext_dir_4
    ext_dir_5
    ext_dir_6
    ext_dir_7
    ext_dir_8
    ext_dir_9
    ext_dir_10
    ext_dir_11
    ext_dir_12
    ext_dir_13

In Cinema 4D I tested running, saving and accessing files from folders within “next_dir_13”. There were no problems with Cinema 4D.
