The interrupts you speak of are 16 bit DOS items but C++ Builder is for 32 
bit Windows and interrupts are banned from Win32 application programs.

For a volume name try the Windows function GetVolumeInformation.

For file searching try the Windows functions FindFirstFile, FindNextFile and 
FindClose.
