IPRO Tech, Inc. - LFP File Format

LFP files (also called load files) are used to build the image database and to instruct IPRO View how to display a project’s images. The image’s file location; file type, boundary, and Bates number make up the LFP file.

Here are three methods for creating an .LFP file.

First, the discovery vendor provides an LFP file upon completion of the imaging phase for a project or case.

Second, one can use IPRO's free utility, IConvert.

This is a free download at http://www.IproCorp.com.

The IConvert tool will convert many load file formats to either LFP or other software formats, such as Summation and Opticon. It is a handy tool for people who don't even use any other IPRO products internally.
Third, manually edit or create an LFP file using a text editor.

Each record (or line) in the LFP file begins with a 2-letter code that determines the action the viewer will perform. To load an image, we will start the line with IM.

Commas separate some parts of the record along with semi-colons for the rest of the line. The command in the LFP file takes effect after you load or import the LFP file. (Import > Import LFP File from the IPRO Tech Utility menu).

Here are two examples of an LFP record. In our examples, we use the MSC collection. It contains two documents, two pages each. The volume name is MSC001.

Example 1: Single Page .TIF files

IM,MSC00014,D,0,@MSC001;IMAGES\ 00\ 00;MSC00014.TIF;2
IM,MSC00015,,0,@MSC001;IMAGES\ 00\ 00;MSC00015.TIF;2
IM,MSC00016,D,0,@MSC001;IMAGES\ 00\ 00;MSC00016.TIF;2
IM,MSC00017,,0,@MSC001;IMAGES\ 00\ 00;MSC00017.TIF;2

Example 2: Multi-Page .TIF files

IM,MSC00014,D,1,@MSC001;IMAGES\ 00\ 00;MSC00014.TIF;2
IM,MSC00015,,2,@MSC001;IMAGES\ 00\ 00;MSC00014.TIF;2
IM,MSC00016,D,1,@MSC001;IMAGES\ 00\ 00;MSC00016.TIF;2
IM,MSC00017,,2,@MSC001;IMAGES\ 00\ 00;MSC00016.TIF;2

Note: Because the files are multi-page, the entire bates range (or image key range) must point to the same .TIF file. As example, MSC00014 contains both "14" and "15". Therefore, to view page 15, the computer must display MSC00014.TIF.

The following provides a breakdown of the fields:

Value	Description of Purpose
IM	Import code identifier (Importing New Page/Image database record)
MSC00014	The image key/document id number
D	Document designation; only designate the first page of each document.
0	Offset to the Tiff file. Always 0 for single page tiff files. When creating Multi-Page Tiff files, this number will increment for the pages within the file. (If there is an 11 page document, the offset would start at 1 and end at 11 and the next tiff file would start over at 1.
@MDEMO	CD volume name
IMAGES\00\00	Directory path on the CD for the image
MSC00014.TIF	Filename for the image.
;2	Tells IPRO the Types* of image file, e.g. tiff, PDF

*Supported Image Types and their specification in the LFP file are:

Type 1 is for IPRO Tech image from DOS-Based version, still supported (.IMG)
Type 2 is for Standard single and multiple page black & white or color TIFF (.TIF)
Type 3 is for IPRO Tech stacked TIFF (.STF)
Type 4 is for Color image (.BMP, .PCX, .JPEG or .PNG)
Type 5 is for black & white .PDF
Type 6 is for Color .PDF
Type 7 is to Auto-detect the .PDF type, e.g. Color or Black & White
