Angry How in the heck, do you get zero byte files?!

I downloaded a trial version of this software. I find that I have 13,618 zero byte files. Which ain't bad, they're zero right? They are consuming 106MB of space!

If a program creates a file but never writes data to it - viola, a 0 byte file. Looks like windows goes ahead and allocates a sector for the file anyway.

Have you run scandisk lately?

The way the file systems work, you have clusters within the sectors. The clusters are of a particular size (say 4k), and you cannot have more than one file occupying a single cluster ... though you can have one file occupying more than one cluster.

So, in reality, while the file's size may be 0 bytes, it's still taking up 4k of your disk (or, however large your cluster sizes are).

I know NTFS will do 512byte clusters, on up to 4k by default, depending on partition size. I can't remember the exact breakdown, but I think it's up to 2GB partitions = 512byte clusters, over 2GB partitions = 4K clusters. It can also be configured to go up to 64k clusters, regardless of partition size, though why anyone would want to waste that much space ... I have no clue.

FAT32 is 4k on up to 32k depending on partition size. I can't remember the breakdown though. I believe it's 2GB = 4k, over 2GB = 32k

FAT16 is 2k for partitions under 512meg, and 32k for any partitions over 512meg.
