Unzipping files from a zipped folder

[Former Member]

Hi,

I need unzip files stored in .zip folder using ABAP. Could you please tell me of a utility/Funtion Module or any other method which exists for the same?

Thanks a lot

Hi Mohammed,

you just have to execute an external program from your ABAP.

For example, if the ZIP file is in the client computer you have to use the WS_EXECUTE.

Have fun

WS_EXECUTE is obsolete and should be avoided. Try CL_GUI_FRONTEND_SERVICES=>EXECUTE instead.

If you are a very recent support package level you might have the class CL_ABAP_ZIP. (I'm not sure what SP this is, it might not even be delivered yet). You can read the file to ABAP as a binary stream and then unzip it with this class. This class is different than CL_ABAP_GZIP in that it understands the ZIP file format and the CRC check. CL_ABAP_GZIP can only compress and decompress data streams.

Hi Thomas,

your CL_GUI_F... is from the release 4.6 or 4.7 ?

At least 4.6C. I don't have any systems older than that to check on. The class itself has a created on date of 12/14/1998.

Hi,

I've tried using CL_GUI_FRONTEND_SERVICES=>EXECUTE but I do not know what to pass in the 'PARAMETER' argument.

Should it be some command to unzip? Please advise.

Thanks

Hi,

When calling the "Execute" method, give "Winzip32.exe" in the "APPLICATION" exporting parameter and in the exporting parameter "PARAMETER" give the value "-E <zipfile - with full path> <Folder to be extracted>"

hope this helps....

Thanks & Regards,
