RDRVSX32: FAT32 RAM drive for HimemSX (Announce)

Can someone confirm if I have correctly setup a FAT32 RAMdrive in the first 4GB of memory (XMS). The relevant FreeDOS (RC5) FDauto.bat lines are...




devload c:\freedos\bin\himemX.exe
c:\freedos\bin\rdrvX32.exe 1400M
copy d:\nulll.txt g:\G
copy d:\1 g:\1_Gbyte
dir g:\

rem himemX.exe 6,074 bytes Oct-29-2020
rem RdrvX32.exe 3,682 bytes Mar-14-2022
rem 1400M is about the maximum available for my computer




and the output produced is



Volume in drive G is RDRVX32

Dir of G:\

1_Gbyte 1,073,741,824 ...
G 0 ...

2 file(s) 1,073,741,824 bytes
0 dir(s) 392,822,784 bytes free




I booted off a USB stick (laptop in Legacy Mode) and the USB stick is the C:\ D:\ E:\ drives and drive F is a DVD drive (in the laptop).

At present I have trouble copying a file bigger than 64Mbytes from the USB stick to a FAT32 drive in the Super Extended Memory (hence why I wanted to see if I could copy to a FAT32 drive in normal Extended Memory).


Question - how can I tell if I actually have a FAT32 drive? In windows I can use File Explorer to tell me - but in DOS?
