hi,

I am uploading zip file data from client application server, and after recieving the data, again i am downloading the file into Zip format to the sap application server. After downloading is done, recieving message is saying that <b>"n number of bytes has been transferred"</b>. while i am trying to open the file then it is giving the message as follows <b>"Compressed (zipped) folder is invalid or corrupted".</b>

So, do any body have any idea to solve this problem?

send me the code when you download the file in zip format .

may be it is not formatted properly.

Also you can following classes.

CL_ABAP_GZIP Class for (De)Compression (GZIP)

CL_ABAP_GZIP_BINARY_STREAM Class for Data Compression (GZIP, Streaming)

CL_ABAP_GZIP_TEXT_STREAM Class for Text Compression (GZIP, Streaming)

CL_ABAP_UNGZIP_BINARY_STREAM Class for Data Decompression (UnGzip, Streaming)

CL_ABAP_UNGZIP_TEXT_STREAM Class for Text Decompression (UnGzip Text Streaming)

CL_ABAP_ZIP Zip Utility

Please reward if useful.
