When restoring files from the CrashPlan console on a Windows system, you may encounter an error stating that the downloaded .zip file is invalid. This article explains the cause of the issue and gives methods to troubleshoot the error.
Windows 8.1 and Windows 10.
There is a 260-character path length limit on Windows which can cause web restore .zip files to fail to unzip and display an error. This error appears because the file path of the extracted contents of the .zip exceeds the 260-character limit enforced by the Windows API.
To open the zip file:
- Download and install a third party extraction software, such as 7zip or WinRAR.
Both are free utilities that are not bound by the Windows API character path limit.
- Use the extraction software to extract the downloaded .zip.
