Hi @Kumar, Ravi Ranjan ,

Welcome to Microsoft Q&A platform and thanks for posting your query here.

As per my understanding, you are facing error while trying to unzip the zipped file via copy activity in azure data factory .

Could you please share the screenshot of copy activity configuration to let us know what compression type are you using?

• The cause of the error could be that your zip file is compressed by the algorithm of "deflate64", while the internal zip library of Azure Data Factory only supports "deflate".
• If the zip file is compressed by the Windows system and the overall file size exceeds a certain number, Windows will use "deflate64" by default, which is not supported in Azure Data Factory.
• On the other hand, if the file size is smaller or you use some third party zip tools that support specifying the compress algorithm, Windows will use "deflate" by default.

Kindly go through the following troubleshooting document : Unsupported compression causes files to be corrupted and let us know if it was helpful. In case it's not helping, kindly revert back in comment box with further update on the issue. Thanks
