Version: 0.52

by: Uesp [More]

EsoExtractData is a Windows command line utility program used to extract data from ESO's MNF/DAT files. For complete documentation see the Online Manual for EsoExtracData.

Features

Extract filenames and data from MNF/DAT files.
Save meta data on the files stored within MNF/DAT files.
Convert DDS files to PNG.
Convert LANG files to CSV and Pootle compatible TXT files.
Convert CSV/TXT back into LANG files.
Compare LANG files for differences.
Options for full or partial extraction of data.

Installation

Download the ZIP file
Unzip into a directory of your choice (preferably a new directory).
Run the program from the Windows command line (ex: Start::Run::cmd) or similar shell.

Typical Usage

IMPORTANT NOTE -- Exporting all files from the three ESO MNF files will take several hours and require over 100GB of disk free space.

View basic program usage and command options:

Code:

EsoExtractData --help or EsoExtractData -h

Extract the given MNF file and outputs to the given path:

Code:

EsoExtractData \path\to\game.mnf \export\path\

Extract the MNF file and outputs a ZOSFT and MNF directory listing to the specified files:

EsoExtractData \path\to\game.mnf \export\path\ -z \export\path\zosft.txt -m \export\path\mnf.txt

Converts all DDS files recursively in the given path:

Code:

ConvertDDS \export\path\

v0.52 -- 25 August 2022

Added the --debugoutput/-v option for outputting additional messages to the log and output. Default is off (so less messages). Set a bunch of error/warning messages to debug only. Note that all messages are still saved to the log file.
Fixed the format of the subfile index which prevents a bunch of error messages from the ESO00000.DAT file.
Adjusted tab levels of text output for a little neater visual output.
Introduced the EsoExtractDataGui program (simple Windows graphical program for basic extraction).
Fixed a memory leak when converting RIFF files to WAV.

[b]v0.51 -- 28 April 2022[.b]

Added the --matchfilename option for only outputting files that contain the given sub-string.
Added the --baselangfile option that uses the given LANG file as for base/missing entries when creating a new LANG file.

v0.50 -- 28 June 2021

RIFF files are automatically converted to OGG/WAV files. Use the "--noriffconvert" command line option to disable.

v0.42 -- 30 April 2021

Removed extra "." in DDS files exported from XV4 files.
Model/animation names from GR2 Granny files are used to output named files if possible.

v0.41 -- 17 September 2020

Removed the -c/--convertdds option.
Added the --luafilelist option.
Added the --luastartindex option.
Added the -y/--fileext option.

v0.40 -- 6 February 2020

Changed to a 64 bit build (to support Oodle decompression).
Supports the new DAT format introduced in update 25 PTS.
Skips empty DAT files which reduces the number of error messages.
Added the "--oodleraw" option which saves subfiles in their original Oodle compression format.

v0.34 -- 30 May 2019

Fix default for the "-n" / "--filename" option.

v0.33 -- 19 April 2019

Added the "-n" / "--filename" option.

v0.32 -- 24 October 2018

Fixed crash from null pointer reference received from Granny API.
Updated Granny2.dll file which permits more original GR2 filenames to be extracted.

v0.31 -- 17 April 2017

Fixed extraction of the ZOSFT from ESO MNF in update 14 PTS files. Unsure how this will work with prior file versions however (is fine with update 13 at least).

v0.30 -- 18 January 2017

Added more matching magic bytes for recognizing GR2 (Granny) files.
GR2 model/animation files are output acccording to their internal original path/filename in addition to their ZOSFT filename (if it exists) and numeric file index. The original path will be created under the "Granny" path in the base export path.
Recognize binary Havok files and assign them with the HKX extension.
Recognize file data containing compressed sub-files and assign them the EsoFileData extensions.
Recognize file data containing unknown ID data and assign them the EsoIdData extensions.
Recognize file data for the PSB2 format (unsure exactly what it is though).
Recognize file data containing more text data (including books) and give it the "TextData" extension.
Recognize "FFX" file data.
Recognize UTF-8 text files starting with the byte order mark EF BB BF and give the extension "TXT".
Recognize the unknown XV4 file which seems to be just a DDS with 12 bytes of extra header data and 4 bytes of extra footer. The original file and a DDS version without the extra header is saved.
Include the "--noparsegr2" parameter to prevent the parsing of GR2 files to extract their original filename.
Added the "--extractsubfile" option for extracting compressed data from some file types:
--extractsubfile none : Default, does nothing
--extractsubfile combined : Outputs all compressed files in one large file.
--extractsubfile seperate : Outputs files individually (Warning: This creates over 1 million files and adds several hours to the extraction).

v0.29 -- 5 September 2016

Fixed an infinite loop due to a truncated compressed file in file eso0002.dat from the update 12 PTS.

v0.28 -- 8 March 2016

Fixed a crash when extracting Game.Mnf data from the Thieves Guild DLC release.

v0.27 -- 4 February 2016

Added support for the 1.9 update on PTS (Thieves Guild DLC) for finding the ZOSFT in the ESO.MNF file. File index for the ZOSFT was changed from 0xFFFFF to 0xFFFFFF.

v0.26 -- 19 August 2015

When using -d the changed CSV file contains the original translation text supplied with -g if it exists in the last column ([id columns], [new], [old], [translated]).

If the ID file used with -i and -i1 is the same you can omit one or the other parameter on the command line. For example, the following commands would be identical:

Code:

EsoExtractData -g tr.txt -i id.txt -d old.txt new.txt -i1 id.txt -i2 new.id.txt
EsoExtractData -g tr.txt -i id.txt -d old.txt new.txt            -i2 new.id.txt
EsoExtractData -g tr.txt           -d old.txt new.txt -i1 id.txt -i2 new.id.txt

v0.25 -- 28 August 2015

Added the "-d" option for comparing LANG/CSV/TXT files.
Added the "-i2" option for specifying the second ID file when comparing files.
Added the "-g" option for specifying a source text for unchanged entries.

v0.24 -- 9 June 2015

Added the "-i" option to input an ID text.
An ID file (.id.txt) is output when converting a LANG file.
Convert a text file along with an ID file to a LANG file.

v0.23 -- 11 April 2015

Added the ''-t'' option for saving LANG files in a plain text format.

v0.22 -- 9 April 2015

Added the "--posourcetext" to use the source text column (2) in a PO-CSV file when converting it to a LANG file.
Assume a PO-CSV file (3 columns) when the -p option is used with -x.
Fix the location column (1) when creating a PO-CSV file (offset was used instead of index).

v0.21 -- 9 April 2015

Escape quotes in text as double-quotes ("") instead of \" in CSV files to import correctly.
Added the "-o" option for specifying the output filename for -l/-x commands.
Added the "-p" option for outputting LANG CSV files in a PO compatible format.

v0.20 -- 9 April 2015

All cells are quoted when saving a LANG file as a CSV.
Translate DOS linefeeds in LANG file texts as "\r" (was "\n" as previously).
Convert a language CSV file back to a LANG file using the "-x" option:
First row must be a header: ID,Unknown,Index,Offset,Text
Column order is currently fixed.
Convert \r, \n and \" to their respectice characters.
Text column must be quoted to preserve commas in texts.
Resulting LANG file will be larger than the original due to duplicate texts not being merged.
Output filename will be the same filename with ".CSV" replaced with ".LANG".

v0.18 - 23 November 2014

Fixed output of Game.Mnf with filenames.

v0.17 - 7 November 2014

Name changed from EsoExportMnf to EsoExtractData.
Now has better, automatic loading of ZOSFT entries for filename correlation.
Fixed incorrect filename assignment to files with the same ID.
Added missing , to MNF file table CSV export.
Added the "UserData" column to the ZOSFT file table CSV export. Currently is the number of file entries found in the MNF data.
Converts any .lang file to a CSV format if it can.
Language file now exported in a normal CSV format (with commas and internal double-quotes escaped to \").
Added the -b/--beginarchiveoption to start at a specific DAT file index.
Added the -l/--lang option to convert a .LANG file to a CSV.

v0.16 - March 2014

Updated to support the patch for the 14 Mar 2014 beta.

v0.15 - February 2014

Updated to support the patch for the 8 Feb 2014 beta.

To try and respond to some of the issues mentioned:

The -c/--convertdds option was removed for a few reasons. The old reason was because it was crashing on some DDS files (this may have been fixed by a library update, I'll have to retest). The other was related to compiling issues after moving to 64-bit (it wouldn't compile any longer with the Devil library, no idea why). So for that update I just removed it and forgot to look at it again. Will see if I can readdress it in a future update.
A more detailed description of the command line parameters can be found at Online_Mod:EsoExtractData on the UESP wiki (although I forgot to add the last 3 added).
- --luafilelist [filename]: If this option is specified a list of all files with a ZOS file table entry is output to the given LUA file in the format:
  Code:
```
[Index] = "Filename",
```
  where Index starts at --luastartindex or 1 by default. This was a request from someone who needed a list of all DDS files in a LUA format.
- --fileext [ext]: Only extract files matching the given extension (or technically filenames that end with the given string).
Looks like I've forgot to include the ConvertDDS.bat script as well as NConvert.exe. I'll include them in future releases.
The "fail" messages at the start of ESO.MNF are "normal" in that there are files specified in the MNF directory that don't seem to exist (offsets exceed the end of the DAT files). I haven't figured a way of separating these known errors from an actual error.

These are really important questions I wonder answers to.

If it helps any, the NConvert utility mentioned in the readme for this version works well enough to convert .dds to other image formats, once this utility extracts the .dds files.

Baertram Super Moderator Forum posts: 4546 File comments: 5616 Uploads: 77	Is there some more info available on the new parameters? Here my assumptions as I was not able to find anything on your website's documentation about them so far: --luafilelist Creates a file list of extracted files as lua table format? --luastartindex Define an index where to start the extraction (but what index is this? 1 = 1st file found in total archves?) --fileext Only extract files with this given file extension, e.g. .dds for the texture files?

Slerio Forum posts: 0 File comments: 12 Uploads: 0	Can you extract with this the Bard songs ? they are sadly nowhere else official and they are also Translated AKA in german the bards sing german and stuff. Command needs to be Code: EsoExtractData.exe "E:\Eso\Zenimax Online\The Elder Scrolls Online\depot\eso.mnf" "E:\Eso\Export\Eso\Depot" What file should we actually target with this ? the MNF file inside client ? i only get a 700mb sized from that same for the one in sound. ok its the file inside the Depot Folder. I added the command as needed to be correct just adjust the path. Last edited by Slerio : 08/26/20 at 05:57 AM.
