Convert an Opticon OPT to an IPRO LFP
Opticon OPT and IPRO LFP are both page-level image load files — they point a review tool at images on disk — but they're structured differently, which is why moving between Concordance/Opticon shops and IPRO shops needs a converter. An OPT row is seven plain comma-separated columns: key, volume, path, doc-break, folder-break, box-break, page-count. An LFP IM record packs the same information into a different shape: IM, key, document flag, box, then an @-token that bundles the volume, directory and filename with semicolons, then offset and page count.
The converter parses the OPT into a neutral page model — key, volume, path, and the document grouping implied by the doc-break flags — then writes IPRO IM records from it. The "Y" doc-break becomes the LFP "D" document flag; the single image path is split into its directory and filename so it can be repacked into the @VOL;DIR;FILE token IPRO expects. Page grouping is identical on both sides, so a parent document with three pages in the OPT is a three-page document in the LFP.
Both formats are image references only — no privileged text — but they still describe your production's structure, and that stays on your machine: conversion is entirely client-side.

How to convert OPT to LFP
- Drop the .opt file into the converter.
- Select IPRO LFP as the target format.
- Convert. The .lfp downloads with one IM record per page and the D flag on each document's first page.
- Load the LFP into your IPRO-based review or production tool.
Questions
Are the image paths preserved?
Yes. The OPT path (e.g. IMAGES\ABC0001.tif) is split into directory and filename and repacked into the LFP @volume;directory;filename token, so the image still resolves to the same file.
What happens to folder and box breaks?
OPT folder-break and box-break flags are read into the page model. LFP represents document structure through the D flag and box numbers; the converter maps the document boundaries faithfully, which is what review tools key on.
Is this lossless?
For the data both formats share — keys, volume, path, and document grouping — yes. Converting OPT → LFP → OPT reproduces the original document and page structure.
