How many letter drives can Windows Have? What to do when you run out?

[Alciel]

Just a quick question about Windows 7 and 10, I plan to be upgrading to Windows 10 sometime next week.

My only problem is that I have a of partitioned drives, So I want to know if there's a letter drive limit on Windows, And if there is what do I do about it when I reach the limit?

Right now I'm on Windows 7 and currently I have 23 letter drives, I'm not sure why but I also have 2 letter drives that I think aren't useful, Letter drive (I) only has 7.99MB with 4.08MB Free and Letter Drive (K) has 99.9MB with 82.3MB free, I'm not sure they are used for or if they do anything at all, My OS right now is on letter drive (C) but that's not partitioned, I originally thought that I and K were part of C because of my OS, Turns out that's not the case.

If I run out of Letters will I not be able to partition anymore?

I really am curious what gave you the idea to do this? This looks to me like cooking dinner, then cutting up the steak in 20 parts, putting them all in a separate plate, then doing the same thing with the potatoes and bringing 40 plates to eat off to the table. I don't think in my 30 years of working with computers I have ever run across a system setup this way.

Its only 4 Physical Drives inside my PC.

Its as Follows:

From Least GB to Greatest TB

298.09Gb [300Gb](Disk 1) (Not Partitioned but has Letter Drive (F) and (I))

465.76Gb [500Gb](Disk 2) (Not Partitioned but has Letter Drive (K) and (L))

931.51Gb [1Tb](Disk 3) (Not Partitioned Main OS Drive)

1397.26Gb [1.5Tb] (Disk 4) (Partitioned 3 Times Holds letter drives (D), (G), (H), with Logical Drive (E)

The above 4 are all Physical HDDs

The Bottom 2 are Externals:

2794.39Gb [3Tb](External 1) (Partitioned 10 Times Holds letter Drives (N), (O), (P), (Q), (R), (S), (B), (T), (U), (V))

4657.40Gb [5Tb](External 2) (Partitioned 4 Times Holds Letter Drives (W), (X), (Y), (A).

Well to be completely honest, I thought that partitioning was the way to go, Clearly I was wrong and Now I'm trying to fix that.

It seems that my most recent question was overlooked.

Could someone please help me with my last question that I posted?
