Don,

I have found it helpful to archive data by year, creating a new file 
each year  (key99, key00, key01, key02, etc.)  This limits the size, 
allows very old data to be dropped by just deleting the year in 
question, and makes finding stuff easier.

Do you have the key from the two files from before the last posting started?

The key can be transferred to a UNIX or LINUX and bytes can be removed 
or added.  I haven't done it in a long time, but as I recall there is a 
command that can grab x bytes from the front or back of a file and it 
can then be streamed to a new filename.

You need to calculate the number of bytes.

(filesize or 2 gig) /(Record length + 20)

Take the integer part of this number and multipy by (record length + 20).

That number is how big the file must be to be less than 2 gig.

Hope someone can post the command.  My memory is hopeless for this.
