The limits of ZIP files according to the folks who make info-zip:
http://www.info-zip.org/pub/infozip/FAQ.html#limits
statistic limit
number of files 65,536
uncompressed size of a single file 4 GB
compressed size of a single file 4 GB
total size of archive 256 TB
maximum path/filename length 64 KB
I had no trouble creating a zip file from a 4GB file filled with '\0'
bytes:
$ python bennie.py
$ ls -ls test.zip big
12 -rw-rw-r-- 1 jepler jepler 4294967296 Mar 20 14:11 big
4084 -rw-rw-r-- 1 jepler jepler 4174545 Mar 20 14:14 test.zip
I'm using Python 2.3.3 on Fedora Core 2.
#------------------------------------------------------------------------
# bennie.py
def make_4gb_file(f):
f = open(f, "w")
f.seek ( 4 * 1024 * 1024 * 1024 - 1)
f.write("\0")
f.close()
import zipfile
z = zipfile.ZipFile("/tmp/test.zip", "w", zipfile.ZIP_DEFLATED)
make_4gb_file("/tmp/big")
z.write("/tmp/big")
z.close()
