    Compressed Drives (WinXP Sp-2)

    I remember in my Win-98 days that it was possible to have a drive run in a compressed state -- to actually have full operational access to all the files from this state.

    Is this possible with an NTFS drive, and
    if so, how do I accomplish same? and
    Can you "transparently" moves files from a non-compressed to a compressed drive?

    Re: Compressed Drives (WinXP Sp-2)

    From the "Help and support Center" installed on ALL XP machines.

    To compress a file or folder on an NTFS drive
    Open My Computer.
    Double-click a drive or folder.
    Right-click the file or folder you want to compress, and then click Properties.
    On the General tab, click Advanced.
    Select the Compress contents to save disk space check box, and then click OK.
    In the Properties dialog box, click OK.
    In Confirm Attribute Changes, select the option you want.
    Notes

    To open My Computer, click Start, and then click My Computer.
    You can only use NTFS compression for files and folders on drives formatted as NTFS. If the Advanced button does not appear, the file or folder you selected is not on an NTFS drive.
    If you move or copy a file into a compressed folder, it is compressed automatically. If you move a file from a different NTFS drive into a compressed folder, it is also compressed. However, if you move a file from the same NTFS drive into a compressed folder, the file retains its original state, either compressed or uncompressed.
    Files and folders that are compressed using NTFS compression cannot be encrypted.
    You can choose to display NTFS-compressed files in a different color. For more information, click Related Topics.

    Dave:

    If I compress an entire drive, and then install something new, or copy an entire new folder onto that drive, it will also be compress, since the entire drive would be default include the root directory, and therefore all folders/directories installed or copied onto the drive after the compression, would fall into the

    "If you move or copy a file into a compressed folder, it is compressed automatically. If you move a file from a different NTFS drive into a compressed folder, it is also compressed"

    realm, correct?

    Re: Compressed Drives (WinXP Sp-2)

    I'm not Dave but you are correct. You might want to read MSKB article 307897 for more details on this, because you can compress a folder without compressing its contents.

    I'm curious as to what you hope to gain by doing this. Disk space is cheap and compressing an entire drive seems mostly unnecessary, unless you are working with zillions of small (< 32 KB) files. Additionally, as quoted from another Microsoft article:
    <hr>Compression adds overhead to the system because a compressed NTFS file is decompressed, copied, and then recompressed as a new file even when the file is copied in the same computer. If your server is CPU-bound, avoid using compression.<hr>
    While compression does happen on the fly and requires no intervention, why would you want to incur a performance hit?

    I agree with Mark, I will be waiting to see your response to Mark's question.

    I'm constantly tinkering with my system. If I was rich and famous, or just the former, I would have a primary PC and one to tinker on. Since I don't...

    I usually keep a copy of the files on my primary drive, so that I have easy access to pulling back something that gets "lost" without having to extract it from an image. It's along this line that I was looking at setting up a compressed drive to put the copied files on. I had thought about a zip file but that is cumbersome. I need to buy another drive, but while I'm waiting.... I've also considered setting up a virtual machine that I could use for test runs, but I'm not real familiar wit these as yet....

    It's all a question of alternatives.

    Regards,
    Chuck

    It might not be my place to say this, but be extremely careful tinkering with your workhorse/desktop/daily driver just for the sake of knowledge. All it takes is one "oops" and then you'll be swearing for the next few hours or days.

    That said, I still think you would be best to avoid compression of your drive if you can help it. Compressing a volume should really only be used as a last resort because of the overhead mentioned in my previous post - it will affect every aspect of your computing experience. You would first have to wait for the volume to compress, and that can take a lot of time to complete. After that you would still be dealing with extra CPU usage for any access to that volume.

    Virtual machines are great for testing, but you're still looking at disk space for these - so save your pennies and get that bigger hard drive. You can get 200GB for well under two bills if you look.

    True enough... been down that road more than once. Santa needs to bring me a second PC for my various escapades.

    You're probably right. I've already found myself in the "swearing for the next few hours or days" a couple times.

    The extra space/drive is, you're undoubtedly right, the best solution for the storage. And that would leave me with more room for the VM... How much space are we talking about there?

    Re: Compressed Drives (WinXP Sp-2)

    <hr>How much space are we talking about there?<hr>
    There's no easy answer to that question. You'll need at least as much as it takes to install the base operating system plus any applications and/or data you want to use with it. Virtual machines typically use a single file that acts as hard drive for the environment. I would say that for testing, you would want to allocate no less than 3GB for the OS and applications and that's on the light side (for hosting XP).

    If you'll be using Microsoft's Virtual PC product, there is an excellent overview on Microsoft's site. Whilst reading bear in mind that most of Microsoft's minimum recommendations are bare bones, and probably not quite enough to comfortably run. Like the minimum specs for Windows, it's usually just enough to get the thing up and going, but once you start using it you will find that your resources are slim. Virtual machines benefit greatly from a beefy machine.

    Is that storage? Or are memory/resources used in addition to the "regular" amounts?

    While a VM is running, is your regular base system running as well?

    Re: Compressed Drives (WinXP Sp-2)

    Is that storage? No, that's everything. You need to understand exactly what it is that you are doing with a virtual machine... it's in the words. It's a machine, just like your computer, that exists only in software. That means that you start the computer with Windows, and then on top of that already running copy you are installing another instance of Windows that runs on "fake" hardware in the form of the software. As such, the more power - disk, memory, graphics - you can throw at it, the better off you will be. Memory and disk space/speeds are particularly important.

    So the short answer is... yes, memory and resources are used in addition to the base amounts. How much depends greatly upon what you do with the operating system that runs inside of the virtual machine.

    If you want to continue this particular topic, let's start a new thread to keep things easy to follow. <img src=/S/smile.gif border=0 alt=smile width=15 height=15> This is a lot different than compressing a volume using NTFS.

    You've answered the compression questions... I wonder a bit about VM's... you can move it if you'd rather...

    <hr>...I've also considered setting up a virtual machine... <hr>
    We just recently talked about this <!post=in this thread,546,768>in this thread<!/post> didn't we? It was there that you seem to have concluded that the MS product was overpriced for the kind of tinkering you want to do. Seems like you want your cake and eat it too, my friend. You either need a computer for tinkering and playing or to make yourself be more conservative...

    Al:

    There you go trying to make me reasonable. I wasn't aware that 'reasonable' had entered into the techno-enthusiast's lexicon, and certainly not conservative.

    True conservativism is pencil and paer

    But you are right in that I, after tossing out the compressed drive idea, have come a bit full-circle.

    The MS product is expensive but there are others, as noted in the past thread, that are in fact as much as free. So the concept could easily hold going forward.

    'Sides, what's wrong with cake? And what if I want it left over for tomorrow too?
