Load-file redaction is the removal of personal data from the metadata and extracted-text fields of an EDRM exchange index. CPR PD 31B expects electronic disclosure to be exchanged in a workable, searchable form, and a load file (DAT, OPT, or CSV) is the industry-standard way parties do that under whatever e-disclosure protocol the case has agreed. anonym.plus runs locally and keeps the delimited structure your review platform needs.
When this applies
This index feeds documents into a review platform under the case's e-disclosure protocol, often set out in a CPR PD 57AD Disclosure Review Document. Its extracted-text and custodian fields often hold names and numbers you must clear before the load file changes hands.
How anonym.plus handles it
- Open the DAT or CSV in anonym.plus on your device.
- It maps the delimited fields, including extracted text.
- The tool flags names, contacts, and IDs per field.
- Confirm the flags and keep the delimiters intact.
- Replace or mask each confirmed value.
- Save the clean index on your device.
What you need to provide
- The index file (DAT, OPT, or CSV).
- A field map for extracted-text and metadata columns.
- Replace with steady labels to keep field integrity.

Compliance achieved
- Matches the exchange format expected for electronic disclosure under CPR PD 31B.
- Keeps the field structure agreed in the case's e-disclosure protocol, often recorded in a CPR PD 57AD Disclosure Review Document.
- Follows the EDRM model's delimiter conventions for clean, review-ready data.
- Offline work keeps the index inside your firm.

Limitations & cautions
These files are delimiter-sensitive. A stray quote or comma in a swapped value can break a field. Test the output in your platform on a small batch first, and keep the document-reference fields untouched unless you mean to change them.
Frequently asked questions
What is a load file?
It is the delimited index (DAT, OPT, or CSV) that feeds documents and their metadata into a review platform. Parties typically agree its format as part of the e-disclosure protocol recorded in a CPR PD 57AD Disclosure Review Document.
Will redaction break the field structure?
No, if you keep delimiters intact. The tool swaps values inside fields and leaves the structure for your platform to read, matching the agreed protocol.
Are document-reference numbers changed?
Not unless you ask. Reference fields usually stay, since they key the documents in review and in any later CPR PD 31B correspondence about specific items.
