The section below the filenames lets you configure the structure of a record. If you've already configured a record before and saved it, you can reload it by pressing the Load button.
Otherwise, use the Append, Insert and Delete buttons below to add/delete fields to the record.
When adding a field, specify its name, type and size (for strings), then click OK.
In this example, an extractable field called MyField, of type CString, and maximum size of 123 characters is added to the record. The actual length of string extracted from the source file will be detected automatically.
If a field doesn't need to be extracted (ex. an area filled with unknown data), simply uncheck the Extract field option of that field.
After adding fields (the unregistered version only allows 3 fields maximum), the Record size is automatically calculated by summing the sizes of all fields.
Records are extracted in sequence, with no gaps in between. If a gap is needed, simply add a non-extractable field of type "Unknown bytes" as the last field of your record. This field will be skipped (non-extractable), thus allowing you to set a distance between two consecutive records.
Last step is setting the starting and ending offsets for record extraction.
