I would definitely
not recommend wasting precious SSD space with custom skins.
Never ever.
Not in IL-2 1946 and not in IL-2 Great Battles either.
Having the game itself on SSD is always a good idea as it fights all kind of lag and stutters, namely Spawn-Lag on IL-2 1946 and Lag all over the place on IL-2 Great Battles after the 3.001 update.
Skins however are a different thing.
Their files will only ever get accessed once in a game session (from then on, that texture is in RAM) and the files are
large but compared to other files to be loaded they're just very
few and they never come in a bunch.
Therefore parallel access to many files (IOPS = Input/Output operations per second) doesn't cound, seek time doesn't count, all that counts - if at all - is the sequential transfer rate, and in that regard good HDDs are not that much different from cheap SSDs and that's by far sufficient for the task.
As you have suggested correctly Gerhard, the key to success is to use Symbolic Links if you have your game on SSD.
Windows Users will have easy access to Symbolic Links using this tool:
Link Shell ExtensionNow if your game is on SSD, you will want to create a separate Folder on HDD to hold your skins (name it whatever you want, I call it "D:\MyIL2GBFiles" for this time).
Then you go to the game's skin folder.
The default skin folder location for IL-2 Great Battles is:
C:\Program Files (x86)\1C Game Studios\IL-2 Sturmovik Battle of <Stalingrad/Moscow/Kuban>\data\graphics\skins
If you have a Steam installation, the default location is:
C:\Program Files (x86)\Steam\steamapps\common\IL-2 Sturmovik Battle of <Stalingrad/Moscow/Kuban>\data\graphics\skins
Go back one step and
move the "skins" folder to your "D:\MyIL2GBFiles" folder.
Next open up two Explorer Windows.
In one of the windows, you navigate to the IL-2 Great Battles "data\graphics" folder.
In the other window, you navigate to the folder holding your new HDD skins folder, in this case it'2 "D:\MyIL2GBFiles".
Now right-click the "skins" folder inside there and drag it over to the other window, then release the right mouse button.
A menu will pop up from which you select "drop as"->"Symbolic Link".
This will get you a symbolically linked subfolder "skins", which points to "D:\MyIL2GBFiles\skins", inside your IL-2 Great Battles "data\graphics" folder.
Voilá, you're done.
Cheers!
