SAP ABAP - Nested ZIP files

[Former Member]

Hi, My requirement is to zip a file and then zip that into another folder with few more files and place it on App Server. I could do the first zip, but couldn't figure out how to do nested zip. Please help if anyone has done it before.

Example:

1. Zip files A, B, C into Zipper1.zip

2. Zip Zipper1.zip, D, E, F into Zipper2.zip

3. Write Zipper2.zip onto App Server

Thanks,
Murali.

You can v_zip->add( ) any xstring data (content) to ZIP. Even the v_zipcontent which you got from v_zip->save( ). Just make sure you do not use same cl_abap_zip object instance (basic OOP).

Hi,

Not sure why 2 times zipped. I think the logic for first zip will work with files only and the same can not be used to zip - zipped file along with other file.

Technically, you are doing zip for A,B,C,D,E,F..then why not single zip for all these?

Thanks,

Sorry No, I am not doing all the files in a single zip.

My requirement for 3rd party is to generate a zip file which contains "1 zip file with n number of files + some more files".

This is the requirement. If I have to zip all in one zip then I could have done it.

Thanks,

Murali.

What is there to figure out? Second level of archiving is same like first or any other.

Where exactly you have problem?

Perhaps you could share how you did the first zip.

I will share how to zip(including nested zip) once I am done with my development.

Thanks,

"I will share how to zip(including nested zip) once I am done with my development."

You say you've done the first zip. The reason I wanted to see that was that it might give a hint as to why you're finding doing the second zip difficult. A Tomas Buryanek points out - what is there to figure out?

Here is the code for the first zip. It generated Test.zip on the Application Server.

Thank you Tomas. It is resolved.
