Great article, I have few questions. If no, can I use fsutil. My vote of 5 TG Dec Precise and concise information. Good article 0pal Mar Hello, Good article. Have my 5 points. However I would enrich this article with more real-life examples. Besides you have to mention that if user application sends the IOCTL to the system asking to make some range of the file sparse - it is only a "friendly recommendation".

There is no warranty that range will be actually marked. Also sparse range must start at so-called "compression unit boundary offset". In most cases it is 64k alignment but can also be calcuulated "on the fly".

Regards P. Feedbacks about the "SparseChecker" are welcome. Re: Good article Member Jan Member This is exactly what I was looking for when I stumbled across this article! I'm very glad I read the comments! Thank you 0pal! Are you still actively supporting this?

For example, it would be awesome to be able to pass a directory to the application and convert all files within that folder to sparse. Re: Good article ehaerim 8-Oct Can you be generous to provide the source files for your SparceChecker? If the file is sparse or compressed, NTFS may deallocate disk space within the file.

This sets the range of bytes to zeroes without extending the file size. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. This browser is no longer supported. Download Microsoft Edge More info.
