NTFS File Compression

[Guest]

How do you turn off file compression for the entire drive. I have lots of
disk space and would rather have better performance than saving space.
Thanks

I've noticed since I switched to NTFS that some of my files get compressed
and are displayed in blue in explorer. I really don't want my files
compressed.

Open My Computer, r-click the drive, Properties, Uncheck the box.

RELAX. And if you'd waited another five minutes before replying to
your own post (not a good sign) you'd have seen the "DUH!" answer to
your question.

I've been using NTFS compression since the days of 200MB disks and
300MHz procerssors (from memory) in some heavy file I/O applications.
I've never seen a downside and in some specific cases seen spectacular
application speeedups.

Back in the day, I could routinely set the compress property on the
entire C drive.

In general, I don't think you'll see any difference, today.

With some files, it's faster to uncompress the data than to read it in its
uncompressed form.

Consider reading 10,000 spaces. Uncompressed, that's 10K worth of data that
has to be transferred from the disk. Compressed, it's like five bytes
transferred.

I worked on an a DB application that needed to load batches of numeric
data in text files of about 1GB each. The data compressed 10:1 and
the reduced IO made the job run much faster and the disk IO was no
longer the bottleneck.
