Error Message: Cannot Copy File: File System Error (1026)

When you download a file and you click Save This Program To Disk in the File Download dialog box, you may receive the following error message:

This behavior can occur if you do not have enough disk space on the drive that contains the Temporary Internet Files folder.

To resolve this behavior, use one of the following methods:

• Delete unnecessary files on the drive containing the Temporary Internet Files folder.
• Delete files in the Temporary Internet Files folder. To do so in Internet Explorer 4, click Internet Options on the View menu in Internet Explorer, click Delete Files on the General tab, and then click OK. To do so in Internet Explorer 5, click Internet Options on the Tools menu, click Delete Files on the General tab, and then click OK.
• Move the Temporary Internet Files folder to a drive that has more free space. For information about how to move the Temporary Internet Files folder, see the following article in the Microsoft Knowledge Base:
  172949� How to Change the Location of Temporary Internet Files

This behavior is by design.

Files that you download are first stored in the Temporary Internet Files folder, and then moved to the destination folder.

Note that this error message can also appear if the server has problems sending the file because of security issues or network traffic. In this case, the file is never created in the cache because of the bad transfer.
