I am trying to understand the fastfat sample code in wdk. I see in windows explorer that for NTFS, I can rename the volume label up to 32 characters and for FAT it is 11. I tried to change the length to 8 for fat, but windows explorer always allows me to input 11 characters even though it gives an error “invalid length” when trying to give 11 character name. How can I change this behavior through fastfat driver so that windows explorer doesn’t even give the option to input 11 characters and instead it limits the text box with up to 8 characters?

Thanks in advance, Girish.

Thanks for the comment. But what I think is since NTFS can make explorer allow up to 32 characters, there should be something in the driver which informs windows that it can allow up to n number of characters based on which the explorer allows the text box to accept up to n number of characters. Any more comments from anybody, please?
I downloaded and installed ext2 filesystem for windows and formatted my drive to ext2. ext2 supports upto 16 characters. But still from windows explorer, I can input only upto 11 characters. Is this a windows limit or is the driver missing something?
