Below is my code, what I am trying to achieve is walking through the OS generating a MD5 hash of every file the code is functional, however, I receive the error in the title "ioerror errno 13 permission denied: 'C:\pagefile.sys'" when I try to run the file from C:\ is there a way i can run this as an admin? Even when I run cmd as an admin that does not work, thank you in advance.

import os, hashlibcurrent_dir = os.getcwd()
for root,dirs,files in os.walk(current_dir):for f in files:current_file = os.path.join(root,f)H = hashlib.md5()with open(current_file) as FIN:H.update(FIN.read())with open("gethashes.txt", "a") as myfile:myfile.write(current_file),myfile.write(",      "),myfile.write(H.hexdigest()),myfile.write("\n")print current_file, H.hexdigest()

As mentioned in error - Permission denied - since file need to be read for getting md5 of its content. There will be always a case when we don't have read permission .

import os, hashlibdef md5_chk(current_file):try:md5 = ''err = ''H = hashlib.md5()with open(current_file) as FIN:H.update(FIN.read())md5 = H.hexdigest()except Exception, e:md5 = Noneerr = str(e)print errreturn md5,errif __name__ == '__main__':    current_dir = os.getcwd()for root,dirs,files in os.walk(current_dir):with open("G://gethashes.txt", "a") as myfile:for f in files:current_file = os.path.join(root,f)md5_val,err = md5_chk(current_file)if md5_val is not None:myfile.write(current_file),myfile.write(",    "),myfile.write(md5_val),myfile.write("\n")print current_file, md5_valelse:myfile.write(current_file),myfile.write(",    "),myfile.write("Error - " + str(err)),myfile.write("\n")print current_file, str(err)

Please let me know if it is useful.
