EDIT: Solved. The extracted .gz file was actually a .zip file just named .gz!
I have a job which takes gzip files (.gz), not in a tarball, which contain multiple .csv files and decompresses them to a directory.
I'm not able to decompress the gzip files provided using tFileUnarchive and get the error "Not in GZIP format".
Using 7-Zip, I am able to manually extract the files which I suppose indicates that the file is not corrupt?
I understand that multiple files should be tarballed pre-gzip, but this is unavoidable due to the third party's extraction framework.
Any help would be appreciated.
Thanks for posting that you have resolved this issue by yourself.
