Sending large Excel Spreadsheet

We have a utility that can convert a file to an Excel Spreadsheet and email
it to a user. This same utility can also just create the spreadsheet on the
IFS.

For most files it is no problem to send the spreadsheet as an attachment.
Now I am given the task to send the entire parts master file as a
spreadsheet. There are over 89k records and the spreadsheet created is 83
mb. This is too large for our email system to handle so it just chokes.

I can open a blank spreadsheet and use iACS to transfer the data into the
blank spreadsheet, but am looking to rather put the spreadsheet on the IFS
and then transfer it to some location on a shared drive.

Any suggestions? Thanks
