how to extract a gz file

Good morning


Could I ask for some guidance please.

I need upload a data file to my website. This file is a gz data file.

Have downloaded the file onto my iMac (download folder)

This file needs to be extracted or unzipped before being uploaded to my site, what ever the correct terminology is?


Can I do this within my Mac environment or do I have to download a third party application, if I do can anyone recommend one.


Thanks


Shaun

Hello


The file is a gz. On my windows machine ( can I say those words on here) I used 7 zip to do the job. No problems.


The error message "could not not extract".


Deleted the file and downloaded it again. Will not open. I know the file is good because I used the same source on my windows machine. I haven't got my windows machine now, after upgrading to 10, it went out the window. The only reason I used windows was I couldn't work out how to do it on my Mac. I very careful about using third party applications which is why I always ask instead of clicking away on google.

You may have somehow got an odd setting when compressing with 7zip.

If that is the case, then of course windows machine would still unzip.

Why the reason for the .gz compression instead of simply standard zipping?

OS X can decompress .zip files natively.


Anyway, did you try gunzip from Terminal (gunzip -d FullFilePath).

Note: Once entering gunzip -d, you can just drag and drop the

file on the Terminal window and the path will fill in. If there are any spaces

in the path, surround it with quotes.

If I just double click......message...no application available.

It auto-unzipped for me.


If you are having a problem, it might be that the association with gz files has been lost.

Select it, Get Info, and in the Opens With section, change it to Archive Utility (you can find it by following Alberto's instructions).

Then, click Change All…
