I am trying to unzip an 18mb zip containing just a single 200mb file
and I get a Memory Error. When I run the code on a smaller file 1mb
zip, 11mb file, it works fine.
I am running on a hosted Apache web server
I am using some code I found on the web somewhere.
def unzip_file_into_dir(file, dir):
#os.mkdir(dir, 0777)
zfobj = zipfile.ZipFile(file)
for name in zfobj.namelist():
if name.endswith('/'):
os.mkdir(os.path.join(dir, name))
else:
outfile = open(os.path.join(dir, name), 'wb')
outfile.write(zfobj.read(name))
outfile.close()
Error Traceback: Line 357 gives the Memory Error
I have removed paths from file references
