That is what GISDK is good for. I was able to write macros about five years
ago to automate the creation of hundreds of geographic files from
TIGER/Line files, when we created a product for distributing the Census
Transportation Planning Package (CTPP) data.

Well, it turns out I was mostly right about the initial File Open dialog
box: you can choose multiple files, but Windows seems to have a limit to
the number; it only processes so many characters, and then issues an error
if the parse stops mid-filename, so you cannot open thousands at once.
Clearly, the Windows programmers never expected people to want to choose
thousands of files at once.
I was wrong about Add File's File Open dialog box: you can only choose one
file at a time. We are considering several improvements, such as having an
Add Folder button, to choose all of the files in a folder, and allow
multiple files to be chosen in Add File's File Open dialog box.
The GISDK function that builds the geographic files from TIGER/Line files
does not care how many files you have chosen, and arrays in Caliper Script
(used to store the file list) can be arbitrarily large and long. The
limitation is in the interface, and we will work around Window's
contribution to the limitations.

Hear, hear!
