File Extension ER1

File type: Data

The ER1 file type is primarily associated with 'AllFusion ERwin' by Computer Associates International, Inc.. AllFusion ERwin Data Modeler is a data modeling solution that can help you create and maintain databases, data warehouses and enterprise data models.

When windows gives you an error message saying that it
"Cannot open ER1 files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

In both cases it is strongly recommended that you
run a free scan for registry errors.
