• Usage : ipf_unpack.exe <IPF file> [decrypt/encrypt/extract]

Decrypt feature will replace the encrypted IPF in argument by the decrypted one.
Make sure to backup your IPF files somewhere before decrypting them.
Make sure not decrypting twice the same IPF.
Once decrypted, the IPF is readable by traditional tools (such as IPF Suite).

Encrypt will restore a decrypted IPF in argument to an encrypted one.
Make sure not encrypting twice the same IPF.

Extract takes a decrypted IPF as argument and generates a list of files. By default, some extension files aren't decrypted entirely ; In that case, only the MD5 of the decrypted is generated. You can use the optional last arguments to notify which extensions you would like to decompress. (e.g : ipf_decrypt.exe SumAni.ipf extract lua xml will extract only lua and xml files inside SumAni.ipf)
