    I have a sencond HD (E:) that I use to backup my files (documents,
    downloads, Music, etc...). I back the up using an utility.

    I noticed that the files in my E: drive are in blue font... What is the
    significance of the blue font?

    Hi Mac,

    This indicates the files are compressed using NTFS Compression.

    You can compress indiviual files, or you can specify Compression for a whole
    volume in Disk Manager (under Admin Tools). If everything on the drive is
    compressed, it probabaly means the whole Volume is compressed. That's okay -
    just means you get more disk space. NTFS compression is very efficient, in
    the performance dimension - there's very little overhead in compressing and
    uncompressing the files (and in fact, some disk IO is even faster, because
    there's less to read from disk). Compressed files can be used like any other
    file, you just open them in an application etc, no special handling is

    Hope it helps,

  3. In addition to your previous answer, you most probably got your files
    compressed when you ran the Disk Cleanup utility and selected Compress Old

  5. No worries, but I think that I was actually wrong about the OP having done
    this, as he actually seems to have said that the whole drive was compressed,
    so maybe the option to format it as a compressed drive was done instead in
    this case.

    On the last point ("no special handling required") there is at least one
    exception, which applies only if you're using VMWare.

    There is a tool the company distributes that allows users to mount a virtual
    volume on a Windows host (allowing you, for example, to manipulate its
    contents without having to boot into a virtual machine). Unfortunately, for
    reasons I've not seen explained, the mount utility will refuse to talk to a
    virtual disk that's hosted in a compressed file, even though VMWare has no
    problems using that compressed file as a disk on a virtual machine.
