Sigh. I have another mac-based 'I've done this before, but forgotten how' question.

[funnypeculiar]

Unzipping zipped files. I know there's an easy way to do it in menus somewhere. Remind me?

Don't you just double click on it?

Nope I get an 'unable to unarchive' msge then...

Sorry, thank you for trying

Are you on MacOSx?

HERE

I see you have tried that. Sorry not sure. Maybe its not a complete zipped file. Is it a download?

No, a data file from a client.
Have had problems accessing it, & for some reason they thought zipping it would make it easier

how annoying

Indeed
Hopeful bump in case anyone has any other ideas.

and another one

probably too late now.

sounds like either a screwed zip file or they've 'helpfully' put a password on it.

OSX will unzip standard zips, gzips,bzips and tars just by double-clicking.. ...so sounds like the file is fecked.
