Repair Zip Files - Common Zip Errors
One of the most common Zip file errors is the message:
"Cannot open file: it does not appear to be a valid archive"
This error can happen when part of the zip file becomes corrupt during an interrupted download, copy or move.
If this error happens due to Internet connection problems (for example, noise on a phone line) then the problem can most easily be solved by discarding the damaged file and downloading a new copy.
