In an earlier post I addresses the issues of converting between FAT file systems, especially between exFAT and FAT16 or FAT32. The bottom line was that there was no “CONVERT” command, and there exists today between FAT16 or FAT32 and NTFS. Actually, it is not even really between, you can use the CONVERT command from FAT 16 to NTFS or from FAT32 to NTFS, you can’t go from NTFS to any FAT file system, and that includes exFAT.
So the question that came up was converting from exFAT to NTFS, how do you do this. And I was thinking of how does CONVERT handles this, and the answer appears to be it doesn’t.
Here is what I did:
I inserted a 1GB USB Flash drive and formatted it exFAT. [I tried this twice, once on a WIndows NT SP3 system with the driver, and Server 2008 SP2 system]
I tried the “convert i: /fs:NTFS” command and got the following message:
CONVERT is not available for EXFAT drives.
Just to make sure, I reformatted the USB Flash drive to FAT32, issued the same CONVERT command, and the drive formatted.
So the conclusion here is that the CONVERT command does not support exFAT as an input file system.
