[Freegis-list] reading Arc/Info geo_dataset

[Jack Varga]

Markus inadvertantly highlighted a larger issue.  Which ESRI "database" 
format are you referring to?  There is the old .e00 and compressed .e00.  
Then there is shape format, SDE and now the concept of an object relational 
data store, geodatabase, that can either reside in an SDE instance or as 
a personal data store in M$ Access (i.e., .MDB) format.

Oh, one other format, and that is INFO's native format on a filesystem.  
The .e00 format is INFO's inherent export format.
