Compressing files into multiple .zip archives with each .zip being independent

I can make self extracting spanned zip files (at 2 GB size) but the problem is I have around 400 of these to make and it will take me too much time, therefore I've been looking for a tool to make it.

Testing it on the mail server can be a great test - thanks a lot, looking forward for the results.

Gotcha.

I've made some changes and they look promising.  I'm currently running a test on my mail server directory using similar settings to what you were trying (Option 1, 2000MB).  It seems to be working fine.  The reason I'm not using 2048MB is that, as I mentioned in a previous post, I am not doing any sort of magical algorithm that attempts to make perfects-sized zip files.   I simply recurse through the input folder and keep a running total of the file sizes.  As soon as that total goes OVER your specified size, I zip those files.  Since you're attempting to push the upper limit of a normal zip file, I'd suggest you use something lower than 2048MB since you run the risk of exceeding that amount.  That why I put "approximate" on the app's interface.  Does that make sense?

In addition, I should be able to support zips greater than 2GB as well.  I'll test that next.

Test #1:


--- ---skwire@hankoku /cygdrive/c/4
$ ls -al e*
-rwx------+ 1 skwire None 2037532760 Dec 18 07:51 email-1.zip
-rwx------+ 1 skwire None 2019501177 Dec 18 08:01 email-2.zip
-rwx------+ 1 skwire None 2010861617 Dec 18 08:07 email-3.zip
-rwx------+ 1 skwire None 2007484481 Dec 18 08:13 email-4.zip
-rwx------+ 1 skwire None 2003196991 Dec 18 08:19 email-5.zip
-rwx------+ 1 skwire None 2049079438 Dec 18 08:40 email-6.zip
-rwx------+ 1 skwire None 1058473649 Dec 18 08:48 email-7.zip

Notes:

1) 12GB+ directory with over half a million files in it.
2) Output mode #1, 2000 as the size setting.
3) It took about an hour for all seven zips to be created.  This was using zero (0) for the compression setting (quickest mode).


Test #2:


--- ---skwire@hankoku /cygdrive/c/4
$ ls -al i*
-rwx------+ 1 skwire None 2956007035 Dec 18 09:12 images-1.zip

Notes:

1) Source folder has 3593 files in it comprising 2.75 GB of space.
2) Output mode #1, 3000 as the size setting.
3) Generated file is a 2.75GB zip.

Here's the latest: http://www.autohotkey.net/~skwire/apps/spinzip/spinzip-setup-v0.0.6.0.exe

Give it a try and let me know if it works any better this time around.  Also, would anybody be interested in encryption or password protection of the generated zip files?

testgames:
wow !!! it works !!!

I've tried it and I got 3 zip files from a 5 GB directory tree.
Thanks a lot, for the quick responses, the clear answers and the willingness to help.
Cheers !
