Hi Dan,
As I told my 5 1/2 year old Nephew the other day when he asked, "I am 55
1/2." ;-)
Say hi to Bill and Steve for me.
To tell for sure if a file or folder is compressed...
Right click a file or folder | Properties | General tab |
Advanced button | Compress contents to save disk space will be checked if
the file or folder is compressed.
Compress contents to save disk space
[[Specifies whether this file or folder is compressed. The contents of
compressed folders are not automatically compressed unless you elect to
compress the contents when prompted.
If multiple files are selected, a check mark means that all the files are
compressed. A filled box means that some files are compressed and some
are not.
Compressed files and folders cannot be encrypted.]]
Your hard drive, that all your files are stored on, is a disk, or a hard
disk drive.
NTFS means NT File System that is how your hard drive is formatted. It
could be formatted in FAT32 (Short for File Allocation Table), but you
can't compress files in that format. Oh yeah, NT stands for New
Technology. Windows XP is really Windows NT 5.1. XP is a marketing name
and stands for eXPerience.
Some files may not compress, like .jpg files, but by compressing them you
can save disk space because of file slack.
[[Files are created in varying lengths depending on their contents. DOS,
Windows and Windows NT-based computers store files in fixed length
blocks of data called clusters. Rarely do file sizes exactly match the
size of one or multiple clusters perfectly. The data storage space that
exists from the end of the file to the end of the last cluster assigned
to the file is called "file slack".]]

So a 1byte file could take up 4KB of disk space if the cluster size is
4KB.
Right click any file | Properties | General tab | Look at Size compared
to Size on Disk.
Help and Support is full of useful information. There is even a
glossary in there.
Another tip that I use all the time.
On the title bar of most dialog boxes in the upper right corner is a [?]
button. As there is in many other Windows items.
Left click [?] and your cursor turns into a ?, click the item you want to
know about. This will display a help topic if there is one.
Right-click the item, and then click the What's This? command.
For example...
Right click any file | Properties | Click the [?] | Move the ? to the
Change button and click it |
[[Click to change the program that opens files of this type.]] should
display.
You have to play around a little and you have to be careful that you have
the ? and do not change a setting that you didn't want to change because
you didn't have the ? as a cursor. Also not everything has a popup
message.
Another tip, if you open something and do not make any changes or aren't
sure, click the Cancel button instead of the OK button to close. That
way even if you did change something, the changes are not saved and it's
like you never opened it.
You can right click that same Change button and What's This? should
popup | Click on What's This? | [[Click to change the program that opens
files of this type.]] should display.
