How to Unzip .Z file in Talend Studio

nishant_nolkha — Tue, 30 May 2017 17:50:26 GMT

Hi Team

I need to unzip a *.Z file using Talend and without using any external software like 7zip or Winrar.

Can you please help me on this.

Regards

Nishant

Use tFileUnarchive for this purpose.
It doesn't support gz format. You need to do it by yourself if you have this kind of files.

Talend do not support all formats (and never will)

but tSystem work well for this. What is the problem with external tools?

Thanks for the suggestion. However the tFileUnarchive is not able to unzip the file.

Error: *.Z , Please wait.. the Archive is not a ZIP Archive.
