Is there a limitation with python's zipfile utility that limits the
size of a file that can be extracted? I'm currently trying to extract
125MB zip files with files that are uncompressed to > 1GB and am
receiving memory errors. Indeed my ram gets maxed during extraction and
then the script quits. Is there a way to spool to disk on the fly, or
is necessary that python opens the entire file before writing? The code
below iterates through a directory of zip files and extracts them
(thanks John!), however for testing I've just been using one file:
zipnames = [x for x in glob.glob('*.zip') if isfile(x)]
for zipname in zipnames:
zf =zipfile.ZipFile (zipname, 'r')
for zfilename in zf.namelist():
newFile = open ( zfilename, "wb")
newFile.write (zf.read (zfilename))
newFile.close()
zf.close()
Any suggestions or comments on how I might be able to work with zip
files of this size would be very helpful.
Best regards,
Lorn
