Hi ,
    I have seen that when we do an ls in a directory containing subdirectories we find that the size of a directory is 512 bytes irrespective of the directory being empty or not. But in the linux system that I have installed in my system each directory shows to occupr 32kb space. I have installed linux on a primary Dos partition i.e mine is a UMSDos kind of installation. Can anybody help me solve this ?
Thanks

The size of a directory as shown in ls -l is the total size of blocks it occupies on the disk, thus the minimum size is the size of a single block. It depends on the filesystem you use. Some Unix installations use filesystems with block size of 512, that's what you probably saw (but that doesn't mean the size is ALWAYS 512; if you put more files in the directory, it will grow to 1024, then to 1536 etc.) Linux standard filesystem is ext2fs and it uses a default block size of 1024. Your filesystem is UMSDOS, built on top of FAT, and it uses the underlying FAT block size. Apparently, in your case it's 32K.
