Summary
You may encounter errors upon attempting to unzip full data export files using Terminal on a Mac you may see:

"End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in WE_00Do0000000000SFDC_30.zip, and cannot find WE_00Do0000000000SFDC_30.zip.zip, period."

With the default Windows zip utility you may see:

"Cannot Complete the Compressed (zipped) Folders Extraction Wizard
The compressed (Zipped) folder is empty.
Before you can extract files, you must copy files to this compresses (zipped) folder.
To close this wizard, click Finish."

With a third party archive management tool you may encounter:

"Unexpected end of data"

Repro
1. Schedule a Full Data Export

2. Download the resulting zip files

3. Unzip each file

Actual Results: One file in the sequence throws an "End-of-central-directory signature" when unzipping using Mac terminal or "The compressed (Zipped) folder is empty" when using the default Windows zip utility.

Expected Results: Unzipping the provided file would not throw an error.

Workaround
You can run the following repair command via Linux to create and open a usable zip file by substituting "WE_00Do0000000000SFDC_30.zip" in the command below with your affected zip file's name:

$ zip -FF WE_00Do0000000000SFDC_30.zip --out <output file name>.zip

Alternatively, you may be able to us a more robust zip management software such as 7-Zip that allows you to unzip the file despite the error.
