4 unerf — BioWare ERF (.erf, .mod, .nwm, .sav) archive extractor
5
7 unerf [options] command archive [file ...]
8
10 unerf extracts BioWare ERF archives, found in many BioWare games as files
11 with the extension .erf, .mod, .nwm or .sav. Moreover, in some games, a
12 .rim file might be an ERF instead of a RIM.
13 There's several different versions of ERFs. This tool supports the ver‐
15 sion V1.0, V1.1, V2.0, V2.2 and V3.0.
16 Supported features:
18 · Archives with stripped filenames. The name hash is searched for in a
19 big lookup table. If it is not found, the file is listed and
20 extracted as a hexadecimal representation of the hash
21 · zlib-compressed files are supported and transparently decompressed
22 · Blowfish-encrypted archives are supported and are, provided you know
23 the password, transparently decrypted
24 · Archives that contain full paths are supported. You can either strip
25 the directory and extract the plain filenames, or substitute the
26 directory separator with a ‘=’
27 · Archives with numerical extension IDs belonging to different games
28 can be aliased accordingly.
29 Unsupported features:
31 · XOR-encrypted archives
32 · Creating directories when extracting archives with full paths.
33 Please also note that by stripped the directories of files in these
35 archives, you might overwrite already extracted files

39 --help
40 Show a help text and exit.
41 --version

43 --nwn2
44 Alias file types according to Neverwinter Nights 2 rules.
45 Neverwinter Nights 2 reuses a few file extension IDs differently
47 than other BioWare games. To correctly read Neverwinter Nights 2
48 ERF archives, use this flag.
49 --jade
50 Alias file types according to Jade Empire rules.
51 Jade Empire reuses a few file extension IDs differently than other
53 BioWare games. To correctly read Jade Empire ERF archives, use
54 this flag.
55 --pass hex
56 Password to decrypt this archive. This password needs to be speci‐
57 fied in hexadecimal notation, even if it's an ASCII string. For
58 example, “4CF223AB” would be a valid password string. “Foobar”
59 would not.
60 --nwm file
61 Calculate the MD5 of this NWM file to complement the decryption key
62 of a HAK file for a Neverwinter Nights premium module.
