copying 40bonn.dat

[rquain@xxxxxxxxxxxxxx (Redmond Quain)]

I would appreciate help on the following.

I have pasted out  of a too big 40bonn.dat file most of what I need but I
wish to save that big file  on a backup device before deleting it in the
main drive.

Should I save along with it the 40bonn.idx file?
