DOCUMENT:Q115165 08-NOV-1999 [pcmail] TITLE :PC Win: Attached Mac Filenames Convert to Windows Incorrectly PRODUCT :Microsoft Mail For PC Networks PROD/VER:WINDOWS:3.0,3.0b,3.2 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Mail for Windows, versions 3.0, 3.0b, 3.2 ------------------------------------------------------------------------------- SYMPTOMS ======== Versions 3.0, 3.0b, and 3.2 of Microsoft Mail for Windows appends a file extension to an attached file received from a version 3.0 Microsoft Mail for PC Networks, Macintosh workstation, even if the file has a valid Microsoft MS-DOS filename. NOTE: MS-DOS supports a filename limited to eight characters for the name and three characters for the extension (for example, FILENAME.DOC). This naming convention is commonly referred to as 8.3 format. CAUSE ===== Mail's naming algorithm assumes that Macintosh file attachments do not have valid filenames and extensions (that is, filenames in 8.3 format). Therefore, Mail moves the decimal to the end of the filename and adds the appropriate extension. The filename conversion is handled by VFORMS.DLL. STATUS ====== Microsoft has confirmed this to be a problem in versions 3.0b and 3.2 of Microsoft Mail for Windows. This problem was corrected in version 3.2a. For information on obtaining this update, query on the following word in the Microsoft Knowledge Base (without the spaces): mailupd NOTE: If the extension does not contain three characters, the updated VFORMS.DLL file drops the extension and adds the correct one. If the extension is three characters, it is left unchanged.
