EsoExtractData is a Windows command line utility program used to extract data from ESO's MNF/DAT files. It is also available at ESOUI.

Installation[edit]

  • Download File:EsoExtractData.zip or at ESOUI.
  • 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.

Usage[edit]

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

EsoExtractData --help or EsoExtractData -h
View basic program usage and command options:
EsoExtractData \path\to\game.mnf \export\path\
Extracts the given MNF file and outputs to the given path.
EsoExtractData \path\to\game.mnf \export\path\ -z \export\path\zosft.txt -m \export\path\mnf.txt
Extracts the MNF file and outputs a ZOSFT and MNF directory listing to the specified files.
ConvertDDS \export\path\
Converts all DDS files recursively in the given path.

Command Line Options[edit]

-h or --help
Show basic help.
-m [filename] or --mnfft [filename]
Save the MNF file directory to the given filename.
-z [filename] or --zosft [filename]
Save the ZOSFT file directory to the given filename.
-s [fileindex] or --startindex [fileindex]
Start exporting from the given file index.
-e [fileindex] or --endindex [fileindex]
Stop exporting at the given file index.
-f [fileindex] or --fileindex [fileindex]
Only export the file with the given fileindex.
-a [index] or --archive [index]
Only export the given MNF index.
-b [index] or --beginarchive [index]
Start exporting at the given MNF index.
-c or --convertdds
Convert all DDS files to PNG. Note that this currently crashes on some DDS files.
-k or --skipsubfiles
Don't extract/save files from the MNF/DAT.
-n [filename] or --filename [filename]
Only extract filenames that match the given string or number. If a number is used it will match the fileindex of the subfile with no extension.
Filenames can include paths however the names are checked both with and without the subfile path. For example, "testfile.DDS" will match both "testfile.dds"
and "path/to/testfile.dds". Match is case insensitive. Wildcards in the filename are not supported. Added in version 0.33.
-l [filename] or --lang [filename]
Convert the given LANG file to "filename.CSV". Also outputs an ID file with the name "filename.id.txt" which is needed when converting a TXT file back to LANG.
-x [filename] or --createlang [filename]
Convert the given CSV file to a LANG file (ex: text.csv to test.lang). The CSV file should be in the same format as one created from the "-l" option including:
  • One header row: ID,Unknown,Index,Offset,Text
  • Column order is currently fixed.
  • Offset column is recomputed when saving.
  • Note that the values \r, \n and \" in texts are converted to their respective 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.
-o [filename] or --outputfile [filename]
Manually specify the output file for -l and -x commands.
-p or --pocsv
Output a LANG CSV file in a PO (Pootle) compatible format. The CSV will have 3 columns instead of 5:
  • Location: "ID-UNKNOWN-INDEX"
  • Source: TEXT
  • Target: Blank
-t or --langtext
Save the LANG file in a plain text format (one text per line, LFs and CRs will be escaped to \r and \n). If combined with -p and extra blank line will be added between the texts to be compatible with Pootle's txt2po utility.
-i or --idfile
Specifies the ID file to use when converting a TXT file to LANG. An ID file is created when converting a LANG to TXT/CSV and must match the file used when converting the TXT file back to LANG. It is a simple text file with one column containing the unique ID for each text in the file.
-d [file1] [file2] or --difflang [file1] [file2]
Compares two LANG/TXT/CSV files for differences. Will output files XXX.added.csv, XXX.removed.csv, XXX.changed.csv, and XXX.lang (or XXX.txt and XXX.id.txt if the -t option is used). For column format for the changed CSV file is [id columns...], [new], [old], [translated]. The two input files don't have to be the same type. If using TXT files use the -i1 and -i2 parameters to specify the associated ID files.
       EsoExtractData -d file1.lang file2.lang
       EsoExtractData -d file1.lang file2.lang -p
       EsoExtractData -d file1.lang file2.lang -p -t
       EsoExtractData -d file1.lang file2.csv
       EsoExtractData -d file1.csv file2.lang
       EsoExtractData -d file1.txt file2.lang -i1 file1.id.txt
       EsoExtractData -d file1.lang file2.txt -i2 file2.id.txt
       EsoExtractData -d file1.txt file2.txt -i1 file1.id.txt -i2 file2.id.txt
Note: 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:
       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
-i1 [idfile] or --idfile1 [idfile]
Use this to specify the assocated ID file if using a TXT file for the first file in a -d parameter.
-i2 [idfile] or --idfile2 [idfile]
Use this to specify the assocated ID file if using a TXT file for the second file in a -d parameter.
-g [file] or --origlang [file]
Use this with the -d command to specify the source for text for unchanged entries. If a text entry has not been removed or changed the text will come from this file. This can be a LANG, CSV or TXT file. If using a TXT file use the -i parameter to specify the associated ID file.
       EsoExtractData -g orig.lang -d file1.lang file2.lang
       EsoExtractData -g orig.csv -d file1.lang file2.lang
       EsoExtractData -g orig.txt -i orig.id.txt -d file1.lang file2.lang
--noparsegr2
Don't parse any GR2 files for their original filenames. By default all recognized GR2 files are loaded and parsed by the Granny DLL in order to extract and output the file to its original filename.
       EsoExtractData eso.mnf --noparsegr2
--extractsubfile combined
Files that contain compressed record/subfile data are uncompressed and their data output to a single file. The combined file format is output in the following format:
       Header (same 16 bytes as original compressed file)
               dword MagicBytes
               dword Unknown1
               dword NumRecords
               dword Unknown2
       x(0...N) Record Data (variable sized)
               dword MagicBytes = "####"
               dword Index
               dword UncompressedSize1
               dword UncompressedSize2
               dword CompressedSize
               dword Index                      (from index file if found)
               dword OrigFileOffset            (from index file if found)
               dword UncompressedSize
               byte UncompressedData[UncompressedSize]
       
       EsoExtractData eso.mnf --extractsubfile combined
--extractsubfile seperate
Files that contain compressed record/subfile data are uncompressed and their data output into individual files within a new subdirectory. Warning: This creates over 1 million files and adds several hours to the extraction.
       EsoExtractData eso.mnf --extractsubfile seperate

  • 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 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.

Known Bugs[edit]

  • Errors Extracting from ESO0000.DAT -- There are many files from ESO0000.DAT are in an unknown/invalid format and do not extract correctly.
  • Errors Extracting from ESO0204.DAT and Greater -- DAT files with index 204 and above are empty (just the DAT header) even though there are file entries in the MNF file. This results is errors when trying to extract file data from the DAT files that doesn't exist.
  • DDS Conversion With -c -- There are some DDS files that will crash the built-in file loader for an unknown reason. Use the ConvertDDS.bat file included instead.

Converting LANG Files[edit]

This is a more in-depth explanation of how to convert LANG files to/from TXT/CSV files related to translating the texts to different languages.

  • Create the Initial Export
        EsoExtractData.exe -l en.lang -o en.orig -p
             Creates: en.orig.csv
        EsoExtractData.exe -l en.lang -o en.orig -t -p
             Creates: en.orig.txt, en.orig.id.txt
Save these files (LANG, CSV and two TXT) for later use as you will need them when re-importing the translated text. Note that the -p option is for importing the file to [pootle.translatehouse.org Pootle]. You can omit the -p for all commands but make sure to be consistent (a file exported with -p has to be imported with -p).
  • Translate the File
Import the en.orig.txt or en.orig.csv into your translation program/utility and translate strings as desired. When finished export the translated strings to a new.txt or new.csv file.
  • Create the New LANG File
        EsoExtractData.exe -x new.txt -i en.orig.id.txt -t -p -o new.lang
             or
        EsoExtractData.exe -x new.csv -p -o new.lang
             Creates: new.lang
The new.lang file can be used in an add-on to "overwrite" the existing LANG file of the game.
  • Update a Partially Translated File
The game continually updates its text over time so you may wish to update a previously exported TXT/CSV file with all the new/updated text:
        EsoExtractData.exe -g new.txt -i en.orig.id.txt -p -d en.lang en.new.lang -o new.updated
             or
        EsoExtractData.exe -g new.txt -i en.orig.id.txt -p -d en.orig.lang.txt en.new.lang.txt -i1 en.orig.id.txt -i2 en.new.lang.txt -o new.updated
            Creates Files:   new.updated.lang
                             new.updated.lang.txt
                             new.updated.lang.id.txt
                             new.updated.added.csv
                             new.updated.removed.csv
                             new.updated.changed.csv
The new LANG/TXT/CSV file will have all the translated lines from new.txt that haven't been changed or removed in the new LANG file and have all the new texts added. The changed CSV file will contain the new text followed by the original text in the last column. Be sure to keep the 3 new files new.updated.lang, new.updated.lang.txt, and new.updated.lang.id.txt as you will need them for future translations and updates.
