Hi Peter, Pete and Steve and others,
Yet another way of doing the task!
You may be interested to know we have a free downloadable product called Search
Plus that can do a search and replace function on a directory of files. It was
initially designed to globally edit workspaces where tables have changed location
but would work just as well for editing TAB files such as in your case. One
way would be to copy the TAB files to another directory. Then search for the
last few unique characters in TAB file and replace it with the same characters
plus the raster settings. Rename the files and put them back in the original
directory.
If you would like a free copy of Search Plus, download it for our products page
at http://www.spatialplus.com
Regards,
Sue.
