[Mono-dev] Sparse files

[Alan McGovern]

Hi,

Not quite, a sparse file is different to a normal file in how allocations
happen. For example if i wanted to write 1 megabyte at an index of 100
megabytes, a seek + write would result in a 101 megabyte file on the disk.

With a sparse file, there'd actually be 1 megabyte physically taken up on
disk but any program that tries to read that file would see that 1 megabyte
existing at an offset of 100 megabytes. (At least that's my understanding of
it).

Alan,
