TCP and LCP files location...

Question

1°
Observing that Lr displays only very few camera calibration profiles and also very few couples camera/lens profiles (for the brand of camera's I use), I made a thorough search of all ".TCP" and ".LCP" files existing in my computer.
Wow ! ... these files are located in a lot of different places !    This certainly from successive updates.
But, I imagine that Lr5 refers only to one "specific directory", showing only the the profiles stored in it. 
Here all the directories path where I've found those profiles (Win7-64):
LCP files : by us Program Files = Program (not Program Files (x86)
C:\Program Fifes\Adobe\Adobe Photoshop Lightroom 5.7\Resources\LensProfiles\1.0\(Brand name)\LCP Files
C:\Program Files (x86)\Common Files\Adobe\CameraProfiles\Lens Correction\LCP Files
C:\Users\(User Name)\AppData\Roaming\Adobe\CameraRaw\LensProfileDefault\LCP Files
C:\Users\(User Name)\AppData\Roaming\Adobe\CameraRaw\LensProfiles\LCP Files
C:\Users\(User Name)\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\LCP Files
C:\Users\(User Name)\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\Downloaded\LCP Files
C:\Users\(User Name)\AppData\Roaming\Adobe\Lightroom\LensProfiles\LCP Files
C:\Users\(User Name)\AppData\Roaming\Adobe\Lightroom\LensProfileDefaults\LCP Files
DCP files :
C:\Programmes\Program Files\Adobe\Adobe Photoshop Lightroom 5.7\Resources\CameraProfiles\Adobe Standart\
C:\Programmes\Program Files\Adobe\Adobe Photoshop Lightroom 5.7\Resources\CameraProfiles\Camera\(Brand name/Camera model)\ \DCP Files
C:\Users\(User Name)\AppData\Roaming\Adobe\Lightroom\Color Profiles\DCP Files
Now... "where" the profiles (involved in the latest version of Lr5) have to be located ?

What to do if a profile doesn't exist in this "good" directory, but well in another (perhaps from a previous version). Are they usable under Lr5-7 ?
3°
What to do with the directories not more used by Lr5-7 ?
Many thanks for your answers.

Many thanks, Bob
Fm Julieanne Kost's :
Lightroom reads camera and lens profiles "from several locations"...
If you use the Adobe Lens Profile Creator utility to create your own lens and camera profiles, Lightroom installs them here:
X:\Program Files\Adobe\Adobe Photoshop Lightroom 4.2 RC\Resources\CameraProfiles\
X:\Program Files\Adobe\Adobe Photoshop Lightroom 4.2 RC\Resources\LensProfiles\
Well, if I understand, the correct paths at home are :
LCP files → C:\Program Fifes\Adobe\Adobe Photoshop Lightroom 5.7\Resources\LensProfiles\1.0\(Brand name)
DCP files → C:\Programmes\Program Files\Adobe\Adobe Photoshop Lightroom 5.7\Resources\CameraProfiles\Adobe Standart
+             → C:\Programmes\Program Files\Adobe\Adobe Photoshop Lightroom 5.7\Resources\CameraProfiles\Camera\(Brand name/Camera model)
Could the other directories found in my PC been used by other application(s) ? (I also have PS)
Stay 2 other questions:
1. What to do if a profile doesn't exist in a "correct directory", but well in another (perhaps from previous versions).
Are they usable under Lr5-7 ?
May I transfer them into the right place for Lr ?
and
2. What to do with the directories not more used by Lr5-7 ?
Thanks for complementary answers.
