安装python，新建extractpac.py，输入以下内容保存，然后把pac直接拖到py上
import struct, glob, os, sys
def read_null_terminated_string (f, start_offset):
current_loc = f.tell()
f.seek(start_offset)
null_term_string = f.read(1)
while null_term_string[-1] != 0:
null_term_string += f.read(1)
f.seek(current_loc)
return(null_term_string[:-1].decode())
def process_pac (pac_file):
print("Processing {}...".format(pac_file))
with open(pac_file, 'rb') as f:
magic = f.read(4)
if magic == b'FPAC':
count, header_size, unk = struct.unpack("<3I", f.read(12))
files = []
for i in range(count):
entry_dat = struct.unpack("<4Q", f.read(32))
files.append({'name': read_null_terminated_string (f, entry_dat[1]),
'location': entry_dat[3],
'size': entry_dat[2],
'hash': entry_dat[0]})
for i in range(count):
f.seek(files[i]['location'])
f_data = f.read(files[i]['size'])
filedir = os.path.dirname(files[i]['name'])
if not filedir == '' and not os.path.exists(filedir):
os.makedirs(filedir)
with open(files[i]['name'], 'wb') as f2:
f2.write(f_data)
return
if __name__ == "__main__":
# Set current directory
if getattr(sys, 'frozen', False):
os.chdir(os.path.dirname(sys.executable))
else:
os.chdir(os.path.abspath(os.path.dirname(__file__)))
# If argument given, attempt to extract from file in argument
if len(sys.argv) > 1:
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('pac_filename', help="Name of pac file to extract from (required).")
args = parser.parse_args()
if os.path.exists(args.pac_filename) and args.pac_filename[-4:].lower() == '.pac':
process_pac(args.pac_filename)
else:
pac_files = glob.glob('*.pac')
for i in range(len(pac_files)):
process_pac(pac_files[i])
