Summary: Wine and Dosbox use different MS-DOS (8.3) file names Product: Wine Version: 1.3.15 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dos AssignedTo: wine-bugs@winehq.org ReportedBy: spammis@spam.la
MS-DOS and 16-bit Windows programs require file names to consist of 8 letters followed by a 3-digit extension (known as "MS-DOS file names" in Windows 95, sometimes also called 8.3 filenames). Wine and Dosbox both emulate MS-DOS file names, but they do it differently.
Long name: C:\Program Files Wine name: C:\PROG~FBU Dosbox name: C:\PROGRA~1
Thus, a Windows program, running under Wine, may refer to a file as "C:\PROG~FBU\SOMEFILE.TXT" whereas a DOS program, running under Dosbox using Wine's Dosbox implementation, would know the same file as "C:\PROG~FBU\SOMEFILE.TXT". This means trouble if the Windows and DOS programs are trying to interact.
In order to view Wine's MS-DOS names, use certain 16-bit Windows programs (such as the Windows 3.1 file manager). In order to view Dosbox's MS-DOS names, use "DIR" in Dosbox or any DOS program. Dosbox only uses MS-DOS names, so it won't show any other names.
