I receive folders of many (up to thousands) PDFs that need sorted into 256MB or less zip archives.
I'm not sure how to split or sort into 256MB groups.

I started by submitting the folder as a job, upgrouping the job....but not sure where to go next. A hold based on some criteria. a sort based on some regex? Any ideas or direction?

Thank you,

Do the ZIP files have to be smaller than 256MB or do you want to zip a group of files that is smaller than 256 MB?

I guess it is the first case. That is hard without scripting because you cannot predict how big the result will be. Do you have to collect 350MB worth of data or can you collect 400MB? Files that already have some sort of compression obviously compress less well than other files. You could work with some sort of average percentage that you have empirically established, and then take a margin, but if you want to get as close as possible to the 256MB limit you will need a script: try a combination, if not big enough, add a file, if too big, remove it again, etc.

You could submit it as an app idea on the Enfocus Appstore: https://www.enfocus.com/en/appstore/appmatch

Freddy, I believe it was the second case. To assemble a group of files and ZIP-them but the ZIP-file must not be over 256Mb.

It can be solved with a looping flow that check how large the zip-file is and if it has room for more you can unpack it, add some more files to it and check again until it has reached its size.

Hi estaub

I don't know if this below will help you, but may be considering using 7-Zip (if your installation is Windows) + Execute-Command from Switch.

PDF-Tests is a folder of 440 Mb size

1 - You create a splitted archive from 7-Zip :
Resulting Output = 4 files :

05/03/2020 13:49 104 857 600 MyZIP.zip.001
05/03/2020 13:49 104 857 600 MyZIP.zip.002
05/03/2020 13:49 104 857 600 MyZIP.zip.003
05/03/2020 13:49 3 249 686 MyZIP.zip.004

Each file is max 104 857 600 bytes, 100 MB (the last one [004] is 3 MB in this example).

2 - Store / Move the resulting folder with SWITCH where you need to.

3 - Later, you re-use 7-Zip to extract the whole content content :
The whole content is unarchived/unzipped :

I don't know if it is you're really expect, may be it could help

Ciao

For a 256 MB file size each max

The exact MB size of the final zip does not need to be maximized, it just can't be larger than 256 MB. Generally the approach can be: sort PDFs into 256 MB batches and then zip each batch into whatever MB size it comes out to. These are variable data record archive batches to deliver back to a customer. I'll look into the looping approach and 7-Zip (I haven't used Execute Command yet). We unfortunately do not have the scripting module.

Has anyone been able to split a job into smaller jobs by file size? If that is possible each job could then be zipped.

Thank you for the responses.
