There are 3 formats in PL/SQL Developer:

* Oracle exp/imp format
* SQL Inserts format
* PL/SQL Developer format

The first simply calls Oracle's exp.exe and imp.exe executables with the corresponding parameters to create or read the dump file.

The 2 other formats will read the table data and write it in the form of a file with SQL insert statements or a proprietary compressed data file.
