Unzipping a Rebex zipped File

Question

I zipped a file in C# using Rebex DLLs. But , I am unable to unzip that file in IBM Mainframe's zOS and SUNOS(Solaris Unix Operating System 5.8). I am unable to unzip even in other versions of SUNOS. This is the error message that I get in SUNOS. Please note that the names "IMMSUM","IMMCPLKP","IMMCNCPT" are file names inside the zip.

Error message from unzip on Sun Station = <<zipfilename>>

indsun1:pdv1:/export/home/is/dvop/testzip $ unzip <<zipfilename>> Archive: <<zipfilename>> error [<<zipfilename>>]: missing 242 bytes in zipfile (attempting to process anyway) error [<<zipfilename>>]: attempt to seek before beginning of zipfile (please check that you have transferred or created the zipfile in the appropriate BINARY mode and that you have compiled UnZip properly) (attempting to re-compensate) inflating: IMMSUM

Are you able to unzip the file using Rebex or WinZip on Windows?

Lukas, Yes I am able to unzip it on windows.

Please run the "unzip -v" command and let copy&paste the version info here. Thanks!

Lukas, Please see the results for the "unzip -v" command

Please note that I have posted as three different comments because of the limitation in the number of characters.

Answer 1

Please ensure you uploaded the zip file using BINARY mode (not ASCII/TEXT mode). In ASCII mode line endings are transformed to fit the target OS (which causes binary files to be corrupted).

You can check the length of both local and uploaded file. They should be the same length.

Thanks it worked :)
