Hello all;
I have a 2017 MacBook pro - running High Sierra v. 10.13.3.
I have a very large zip file, (32GB - all photos) that I cannot open. I get the following error:
Unable to archive "Camera Uploads.zip" into "Camera Uploads.zip.cpgz". (Error 27 - File too large.)
Please forgive me - I have googled until I'm blue in the face, and I just can't figure this out. I'm worried I'm going to lose all those pictures....
MacBook Pro, OS X Yosemite (10.10.1)
In the Finder, click once on your huge zip file, and then press the option key while you right-click on the file. Choose the menu entry: Copy “zipfilename” as Path. This will go on your clipboard as a UNIX file path.
Launch the Terminal application. (Dock : Launchpad : Other : Terminal). On the command line, enter the following:
unzip -tq cmd-v
You are pasting the zipfile path from the clipboard behind the unzip command which will not unzip the zipfile, but will test it for errors. You are hoping for the following output:
No errors detected in compressed data of source.zip.
If there are errors detected, you may never be able to extract the images from the zip archive.
Ordinarily, you could just double-click on a zipfile and macOS would just unzip it. You may need to fetch the free The Unarchiver application from the Mac App Store, and give it a try.
Could be worth a try (at least as a suggestion for other ways to follow):
