What's the difference between these? I have a folder, which I want to burn to a CD, whose size is 500MB but size on disk is 1GB... so will I be able to burn it on a 700MB media or not?

Nope, the inflated number for 'size on disk' is due to the way that operating systems store files. For example, on a particular file system files may have to be stored in 32KB blocks - this would mean that a 0.5KB file would actually take 32KB on disk and a 33KB file would actually take 64KB on disk. It's not related to fragmentation - so a defrag won't change the size on disk.

Extending on what Kier said, you can make it smaller by using FAT32/NTFS or another file system that uses a smaller cluster size. IIRC FAT32 uses 4 KB clusters and NTFS's can vary automatically.--filburt1, vBulletin.org/vBulletinTemplates.com moderator

If the folder is full of small files, you can reduce its "size on disk" for burning by zipping it. Then you get compression in addition to the smaller size overhead of one file.Comment

There are negative sides to this aswell, as it would increase the size of your indexes.Raz - KMC ForumsComment
