Built-in zip extraction doesn't extract all files.
Having a bit of an issue with the built-in Windows 7 ZIP extraction tool.
When extracting files from a ZIP file using the built-in tool, it looks like all the files are extracted, but when viewing the folder the files 'should' be in, only X amount actually appear (X meaning, the amount of files that appear is random).
This only happens when extracting to a network location. Extracting to a local disk, the files appear no problem. Also using something like 7Zip also works fine.
