When you restore a file with Microsoft Undelete for Windows and a file withthat name already exists, you receive a message stating "This file alreadyexists." If you type a new filename in lowercase letters, MicrosoftUndelete for Windows saves the file to disk with a lowercase filename.
Because lowercase names are invalid in the MS-DOS file allocation table(FAT) system, many programs cannot access the lowercase-named file.
You may be able to correct this problem using the DEL command and thewildcard character (?). For example, if you want to delete "wina20.386",type del ????20.386 at the MS-DOS commandprompt and then press ENTER. Once you delete the file, run Undelete andrestore the file again.
If this does not work, use a third-party program such as Norton Utilitiesby Symantec or PC Tools by Central Point Software to change the filename touppercase letters.
