Dave,
In the IDV user preference, under System tab, there is a checkbox named
"Write Grib Index in Disk Cache".
When it is checked (by default), the IDV will normally cache grib data index
sets to disk in the default directory: .unidata/idv/DefaultIdv/tmp/nj22. If you
uncheck this box, the IDV will save those index sets to the same directory as
the grib datasets. When you make the change, you need to restart the IDV for
this change to take effect, and you need to make sure the write permission on
this data directory.
Let us know if this is not what you experienced.
