How Import From Interchange File (Coverage) works

NOTE: This tool only works with an ArcInfo license and will only be available in ArcToolbox if you have installed ArcInfo Workstation.

An ARC/INFO interchange file can be used to transport coverages; INFO tables; text files, such as AML macros; and other ARC/INFO files between various machine types. An interchange file contains all coverage information and appropriate INFO table information in a fixed-length ASCII format.

There are many ways to use Import From Interchange. One way is to transport a coverage and its associated INFO tables. Each coverage file and its INFO tables are read from the interchange file into an output coverage. This is done by using the keyword COVER for the first argument. Another way is to transfer an INFO table. In this case, any INFO pathname/username can be used to specify the name of the output INFO table. This option is invoked by using the keyword INFO for the first argument. A third way is to use Import with the TEXT option to transfer key files, AML macros, and other text files.

If multiple volumes are provided by Export To Interchange, the ASCII interchange file name for Import from Interchange must be in the format <interchange_file>.E00 through <interchange_file>.Enn, where nn is the last volume ID. Even if only one volume is produced, this file name must have the .E00 extension.
