.DOC Extension Not Appended to Filename with Long Extension PSS ID Number: Q67240 Article last modified on 12-11-1990 PSS database name: W_Os2Word

OS/2

Summary:

Microsoft Word for OS/2 will support the HPFS file system and the ability to use up to 254 characters. Word will also allow very large file extensions. Because a period can be placed anywhere in the filename and appear as often as desired, there is no way to accurately determine what should be considered an extension.

If Word finds an extension that is 24 characters or less, it will not append a .DOC extension to that file; it assumes it already has one. If the extension is longer than 24 characters, it will append .DOC to the filename.

As an example, the filename DEMO.TEXT is saved as DEMO.TEXT and does not have the .DOC appended to the name. As a result, this file does not appear in the default File Open dialog box because Word looks only for files with the .DOC extension by default.
