DOCUMENT:Q102505 17-AUG-1993 [W_NT] TITLE :Filename Doesn't Appear As Expected After File Operation PRODUCT :Windows NT PROD/VER:3.10 OPER/SYS:WINDOWS KEYWORDS: -------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT operating system, version 3.1 - Microsoft Windows NT Advanced Server, version 3.1 -------------------------------------------------------------- When you locate or group files in File Manager and CMD.EXE, files are identified by the filename extension that comes after the LAST period in the filename. However, when you perform a file operation, such as copying a file, File Manager and CMD.EXE use the filename extension that comes after the FIRST period. This situation may produce undesired results when you rename a file using wildcards (such as *). For example, when you rename a file called MY.TEST.DOC.TXT by typing, *.BAK, the new filename for MY.TEST.DOC.TXT will be MY.BAK.
