When you download a Zip (.zip) file in Microsoft Internet Explorer, you may experience either of the following behaviors:
The file appears to download, but the file compression program that you use (for example, WinZip) opens and displays a blank window.
When you search for the file, you are unable to locate it. The file does not exist on your hard disk.
If you are running Microsoft Windows XP, and you use the Compressed (zipped) Folders feature as your file compression program, you receive the following error message:
The Compressed (zipped) Folder is invalid or corrupted.
This behavior can occur if you click a hyperlink on a Web page to download a .zip file in either of the following scenarios:
Case 1: You are using Microsoft Windows XP, and the Confirm open after download check box is not selected. -or-
Case 2: The Uniform Resource Locator (URL) to which the hyperlink points uses an Active Server Pages (ASP) or Common Gateway Interface (CGI) file.
You click Open or Open this file from its current location in the File Download dialog box.
Under these circumstances, Internet Explorer does not correctly save the file to the Temporary Internet Files folder on your hard disk after it is downloaded. As a result, you experience either of the behaviors described in the "Symptoms" section of this article.
To work around this problem, use the following procedures.
For case 1: Before you download, make sure that the Confirm open after download option is selected. To verify this:
Click Start, point to Settings, and then click Control Panel.
Double-click Folder Options.
Click the File Types tab.
Scroll down to and click the .zip extension.
Verify that Confirm open after download is selected.
For case 2:
Click the hyperlink, and then click Save or Save this file to disk in the File Download dialog box that appears.
In the Save As dialog box, specify a location to save the file to (for example, Desktop), and then click Save.
When the download is finished, open the .zip file, and then extract the files that are contained in it.
