Looks like the OP saved the filename as a string.
OP, make sure that you are setting the filename keyword, as
well as indicating what variables to save.
Also, read the help on the size function.
Cheers,

I see, you're using size(d) to determine the dimensions...
(read the documentation on how to use it!)
After you restore d, d is actually a string. This is because
-you saved d as a string variable or
-you restored the wrong file or
-???

What do you mean by "the size of my sav file"? the dimensions?
How do you determine it?
The following example works fine for me:
IDL> d=findgen(36,44,32)
IDL> help,d
D FLOAT = Array[36, 44, 32]
IDL> save, filename='xxx.sav',d
IDL> d=0
IDL> restore,'xxx.sav'
IDL> help,d
D FLOAT = Array[36, 44, 32]

You need to specify what variable(s) you want to save:
save, filename='xxx.sav', d
