How to create 1G zeroed sparse file in windows?

Question

In linux:

$ dd if=/dev/null of=mysparse seek=1G count=0
$ du -b mysparse
549755813888    mysparse
$ du -B1 mysparse
0       mysparse

In windows I have been playing with fsutil but I can not get the size on disk to be smaller than the size in the file properties.

Answer 1

FSUtil File CreateNew temp 0x100000
FSUtil Sparse SetFlag temp
FSUtil Sparse SetRange temp 0 0x100000

Answer 2

What @Mehrdad said is correct.

However, whatever you write to the file (even ranges of zero) would be considered data to the operating system (and thus space allocated) and only FSCTL_SET_ZERO_DATA() would allow non-space occupying zeros to be written.

fsutil sparse setflag [file]

would allow a file to be set as sparse file.
