	import os, sys
	from stat import *

	BIG_FILE_THRESHOLD = 10000000L

	dict1 = {} # filesize as key, filename as value
	dict2 = {} # filename as key, filesize as value

	def treewalk(path):
	 try:
	 for i in os.listdir(path):
	 mode = os.stat(path+"/"+i).st_mode
	 if S_ISDIR(mode) <> True:
	 filename = path+"/"+i
	 filesize = os.stat(filename).st_size
	 if filesize > BIG_FILE_THRESHOLD:
	 if filesize in dict1:
	 dict2[filename] = filesize
	 dict2[dict1[filesize]]=filesize
	 else:
	 dict1[filesize] = filename
	 else:
	 treewalk(path+"/"+i)
	 except WindowsError:
	 pass

	
	def printdict(finaldict):
	 for i_size in finaldict.values():
	 print i_size
	 for j_name in finaldict.keys():
	 if finaldict[j_name] == i_size:
	 print j_name
	 print "\n"

	

	
	if __name__=="__main__":
	 treewalk(sys.argv[1])
	 printdict(dict2)
