string @lpVolumeSerialNumber,;
string @lpMaximumComponentLength,;
string @lpFileSystemFlags,;
string @lpFileSystemNameBuffer,;
integer @nFileSystemNameSize

lpRootPathName="C:\"
lpVolumeNameBuffer=repl("X",256)
nVolumeNameSize=0
store space(256) to;
lpVolumeSerialNumber,;
lpMaximumComponentLength,;
lpFileSystemFlags,;
lpFile1SystemNameBuffer
nFileSystemNameSize=0

if GVI( @lpRootPathName,;
@lpVolumeNameBuffer,;
@nVolumeNameSize,;
@lpVolumeSerialNumber,;
@lpMaximumComponentLength,;
@lpFileSystemFlags,;
@lpFile1SystemNameBuffer,;
@nFileSystemNameSize) = 0
wait wind "ERROR"
else
for i=1 to 100
if asc( substr( lpVolumeNameBuffer, i, 1)) = 0
exit
endif
endfor
lpVolumeNameBuffer=left( lpVolumeNameBuffer, i-1)
? lpVolumeNameBuffer
