Message WZ13

This message is displayed if WinZip^® was unable to open the requested archive. Specific causes for this error include:

• The archive file may be compressed using a newer format than what is supported by the version of WinZip currently installed. Please check the WinZip website to see if there is a newer WinZip version that may be able to open the archive.
• The archive file does not exist or is in use by another program.
• The specified folder does not exist.
• The file is not an archive.
• The archive has been damaged or corrupted.
• There were disk errors or insufficient memory while reading the archive.
• The archive contains invalid or illegal filenames.
• The Zip file does not conform to the Zip standard and contains non-standard data.

If you are working with a Zip file, you can try repairing the file as described in Fixing Zip Files.

If you are attempting to open an IMG or ISO file, please note that WinZip includes support to read and extract from ISO files and disc image IMG files. Many programs use the IMG file extension for what they would term "image data". In such a case, the "image" may be a graphic or it may be a digital image of a disc (or diskette). Attempting to open an IMG file that is not in the expected ISO format is one way to cause WinZip to display this error.

WinZip supports ISO file systems that include ISO 9660 and UDF from 1.02 to 2.6 (a subset of ISO 13346). Usually, CD images use ISO 9660, DVD images use UDF1.02/ISO9660 bridge, and Blu-ray Disc images use UDF 2.5.
