Shanta,

This sounds like it isn't an excel issue, but is related either to XP or
(more likely) the set up of your individual PCs.

Firstly, are these your machines or company machines? If company machines I
would suggest that the best thing to do is contact your IT department. They
know about the set up of your machines, so can help you more than any public
boards because this doesn't sound like something you are doing wrong.

Assuming it's your own machine:
I'm trying to work out what is happening to try to help you find the right
place to look for your answer. On the machine that works:
- When you use Send To are you using the option "Compressed (zipped)
folder" or is there a different instruction?
- When you perform the zip what does the result look like? (is there a
folder with a zip in it and the result still has a .xls extension, does it
create a new type of file with .zip or .rar at the end?)
- When you open the compressed file does a new program or window launch?

When I first read your question it sounded to me like one machine has a
compression utility installed (such as winzip) and the other one doesn't.
However, I think that XP came with a 'preloaded' simple compression utility.
If that is what is broken then I think you would have to go to an XP board
and find out if it can be repaired.

I have 2 computers both using Windows XP.
In one computer I can compress the excel file when I want to e-mail large
files.
I open the file and use "send to" which shows me the option to compress the
file.
In the other computer I do not see this option. I surched for all the help
in compression and zip files with no help. some how, this computer drive
seems to be formatted as NTFS. and I am not sure how to use this NTFS
compression. I did as the help topic suggested, but still the size on the
file has not changed.
Could someone out there help me?
I have to work with large files and cannot do my job without this. Not sure
one is working and other does not.
Thanks.
