SYMPTOMS

When you download a file from the Internet, you may not be prompted for the location in which to save the file that you are downloading. Instead, the file may be opened.

CAUSE

This behavior can occur if you clear the "Always ask before opening this type of file" check box when you download a file. If you do this, files of this type are automatically placed in the Temporary Internet Files folder and opened by the program that is associated with the file type.

RESOLUTION
If you want to be prompted for a download location for the file type, follow these steps:
1. Double-click My Computer.
2. On the Tools menu, click Folder Options.
3. On the File Types tab, click the appropriate file type in the Registered File Types box.
4. Click Edit.
5. Click to select the Confirm Open After Download check box.  
6. Click OK, and then click OK.

MORE INFORMATION

When you first click a link to download a file, the File Download dialog box appears. You have the following options:
• Open this file from its current location
• Save this file to disk
• Always ask before opening this type of file

If you clear the Always ask before opening this type of file check box, you indicate that this type of file should always be opened with the associated program. The file is then downloaded to your Temporary Internet Files folder and opened.

If the "Always ask before opening this type of file" check box is unavailable, there is no program associated with the file type. For example, if you download a file with a .zip extension, the check box is unavailable unless you have installed a program that can open .zip files.
