EsoExtractData
Version: 0.34
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\
v0.34 -- 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.

how is it possible to export a whole list of index ids (start and stop via -s -e doesn't help) or only a whole subfolder?

something with "-a" or "-b"?

The command promt vanishes straight away when I use the .exe.
Same result when using cmd.
Am I doing something wrong?

Edit: okay, it works by doing the following (not sure why this doesn't get explained properly):
- Start: cmd.exe
- type cd C:\WhereEsoExtractIsLocated
(cd for change directory)
- To unpack eso.mnf type:
.\EsoExtractData.exe "C:\Program Files (x86)\Zenimax Online\The Elder Scrolls Online\game\client\eso.mnf" C:\my extraction folder

Adjust accordingly.

Riff/wav

Will there be any plans to update the tool to extract/convert just the riff/wav files in the game?
They also have junk data in the headers (not sure if all of them).

I'm looking for just the sfx and music.
I'd like to create custom ringtones and notifications.
According to WinDirStat, there's 7.5GB worth of .riff files in over 28K files.

Hey, so does this work for the latest updated version of the game - Tamriel Unlimited?

The game.mnf file is now kept in the client folder instead of the game folder, so just wondering. And whenever I try to run the extract command, I keep getting this error message:
Invalid command line parameter received...aborting!

So how do I solve that?

Error

I keep getting this error message:
Invalid command line parameter received...aborting!

I've looked at the wiki page and tried a bunch of different paths, but the same thing keeps coming up even when I try a different command.

Missing convertDDS?

Hi,

The documentation refers to convertDDS.bat, but no such file exists in any version of EsoExtractData that I can find.

Where can I get it?

Thanks!

** edit **

I found it in the revision history at http://www.uesp.net/wiki/File:EsoExtractData.zip
I just downloaded the oldest revision and it was there.

Didn't looked a lot for now.
I just uploaded v0.29 which fixes this issue. It seems there was a truncated compressed file in the eso00002.dat file which caused an infinite loop trying to inflate it. I've successfully extracted everything from the update 12 PTS but let me know if you run into further issues!
Thank you.
