I have encountered a recurring problem when zipping large files using the internal zip command. The zip is created, a zip /test reports okay and the file can be unzipped (using unzip) but the internal structure of the zip is buggy causing other programs to throw errors. For example,

Data_20140514.zip: The file "Landline_20140514.csv" header is corrupt​

It only appears to be the header that's corrupt. The data seems intact.

The zip contained:

5/14/2014 12:44 1,336,266,952 Email_20140514.csv
5/14/2014 12:37 5,032,643,456 Landline_20140514.csv
5/14/2014 12:31 1,746,621,055 Mobile_20140514.csv
