tfileUnarchive Error : "invalid distance too far back"

[Anonymous]

I am trying to unzip multiple files.

I tried following the solution posted here https://community.talend.com/t5/Design-and-Development/resolved-unzip-multiple-folder-and-iterating-... but I am getting an error which I am unable to resolve.

Exception in component tFileUnarchive_1 (tJobETL1)
java.util.zip.ZipException: invalid distance too far back
	at java.util.zip.InflaterInputStream.read(Unknown Source)
	at java.util.zip.GZIPInputStream.read(Unknown Source)

Below is my workflow

tFileListComponent

tUnArchiveComponent

Thanks.

Hi,
In many cases this error occurs for corrupted archive files.
Are you able to rebuild the archive or to get a new or different one?

Hi TRF,
You were right. That Zip file was corrupt. I used tFTPGet to download that zip file.
When I download the same file using WINSCP it comes out fine. Where am I going wrong ?

I got it working.

I changed tFTPGet component. 

from ___ Transfer Mode = ascii  

to ___ Transfer Mode = binary

That solved the issue.

Great!

Binary mode is required as soon as the transfer is not for a pure text file, that explains why you get the error for an archive file.

Thank's to mark your case as solved.
