DynaZip Decompression Does Not Work with Old PKZip Files
Last reviewed: July 21, 1997

Article ID: Q142427

The information in this article applies to:


 * The Microsoft Network versions 1.0, 1.05, 1.2, 1.3

SYMPTOMS
When you attempt to download a file from MSN, The Microsoft Network, you may receive the following error message:

DynaZip UnZIP Error:

The same disk volume cannot be used as both the source and destination

CAUSE
If the Automatically Decompress Files option is selected (the default), files are automatically decompressed using DynaZip when you download them. DynaZip decompression does not work if the file was compressed using PKZip version 1.0.

RESOLUTION
Even though you received the error message, the compressed file has been downloaded. You need to decompress it using a decompression program.

MORE INFORMATION
If you want to turn off the Automatically Decompress Files option, follow these steps:


 * 1) Open the message with the file you want to download.
 * 2) On the Tools menu, click File Transfer Status.
 * 3) On the Tools menu, click Options.
 * 4) In the Compressed Files area, click the Automatically Decompress Files check box to clear it.
 * 5) Click OK.

If you turn off this option, you must manually decompress all compressed files that you download.
