Problem with Zip File after transferrig to UCM server through SOAPUI

Summary

File being transferred successfully, but invalid

Content

Hi All,

 I am using Soap UI to transfer ZIP file to UCM server as part of HDL automation. The file is being transferred correctly, but after getting transferred, it is becoming invalid and showing the following error when trying to open :

Windows cannot open the folder.

The compressed (Zipped) Folder  'C:\Users<>'  is invalid.

There by my HDL import is failing. However, if I upload the same zip file manually (without SOAP UI), it is successful. Can somebody please let me know what could be the possible issue/resolution.

Thanks,
