使用Python來進行檔案的分割與合併是非常簡單的。

python程式碼如下：

splitFile--將檔案分割成大小為chunksize的塊；

mergeFile--將眾多檔案塊合併成原來的檔案；

# coding=utf-8
import os,sys
reload(sys)
sys.setdefaultencoding('UTF-8')
 
class FileOperationBase:
 def __init__(self,srcpath,despath,chunksize = 1024):
 self.chunksize = chunksize
 self.srcpath = srcpath
 self.despath = despath
 
 def splitFile(self):
 'split the files into chunks,and save them into despath'
 if not os.path.exists(self.despath):
 os.mkdir(self.despath)
 chunknum = 0
 inputfile = open(self.srcpath,'rb') #rb 讀二進位制檔案
 try:
 while 1:
 chunk = inputfile.read(self.chunksize)
 if not chunk: #檔案塊是空的
 break
 chunknum += 1
 filename = os.path.join(self.despath,("part--%04d" % chunknum))
 fileobj = open(filename,'wb')
 fileobj.write(chunk)
 except IOError:
 print "read file error\n"
 raise IOError
 finally:
 inputfile.close()
 return chunknum
 
 def mergeFile(self):
 '將src路徑下的所有檔案塊合併，並存儲到des路徑下。'
 if not os.path.exists(self.srcpath):
 print "srcpath doesn't exists,you need a srcpath"
 raise IOError
 files = os.listdir(self.srcpath)
 with open(self.despath,'wb') as output:
 for eachfile in files:
 filepath = os.path.join(self.srcpath,eachfile)
 with open(filepath,'rb') as infile:
 data = infile.read()
 output.write(data)
 
#a = "C:\Users\JustYoung\Desktop\unix報告作業.docx".decode('utf-8')
#test = FileOperationBase(a,"C:\Users\JustYoung\Desktop\SplitFile\est",1024)
#test.splitFile()
#a = "C:\Users\JustYoung\Desktop\SplitFile\est"
#test = FileOperationBase(a,"out")
#test.mergeFile()

程式註釋部分是使用類的物件的方法。
