I am pretty sure that it is not possible. Getting the volume label is
platform dependent.
And I can not find any reference on this in the fileplugin.
On windows you would need to call GetVolumeInformation().
A quick solution for win32 with help from NativeBoosts FFI:
NBWin32Shell class >>getVolumeLabel: aPath buffer: aBuffer size: anInteger
<primitive: #primitiveNativeCall module: #NativeBoostPlugin error:
errorCode >
^ self nbCall: #( bool GetVolumeInformationA (
String aPath,
char* aBuffer,
int anInteger,
0,
0,
0,
nil,
0))
module: #Kernel32
For example use that:
|diskpath buffer label root |
diskpath:= FileSystem disk workingDirectory path.
root := diskpath segments first, diskpath delimiter asString.
buffer := String new:255.
label:=(NBWin32Shell getVolumeLabel: root buffer: buffer size: (buffer
size)) ifTrue:[buffer allButLast] ifFalse:[''].
label
A note on GetVolumeInformation, if you want to retrieve the label of the
current working
directory, you'll have to add a trailing delimiter (c:\ works, c: only
works if it isn't the
root of the current working directory!)
