In open-file dialog , espacially on Windows, are special paths:
Desktop,Download, OneDrive etc
and network paths.
How to read network paths, iterate over network folders?

You need to retrieve a
IShellItem
instance for the special folder you want to list the contents of(in case of networks its
CLSID_NETWORK
). Then you need to enumerate the items of that instance. I currently can't provide you with any code as I'd have to piece it together myself again. However we've used such code at work, so I can show you the necessary functions/interfaces on Monday.
Please note that this will only enumerate those items that Windows discovered by itself as well (thus using the current user's credentials). This means that if NetBIOS browsing is disabled for example (which is the default in Windows 10) then you won't be able to find older shares (e.g. hosted by older NAS). Or if WS-Discovery is disabled on a Windows 7 you won't be able to see shares provided by Windows 10. You can see the used detection method by going to
My Network Places
, changing to
Details
view and then enabling the column
Detection method
(German:
Erkennungsmethode
). It will contain entries like
WSD
,
NetBIOS
and
SSDP
.

I need Windows dirs but also Linux dirs : Downloads , Documents, Uset home (tilda).
And need local network folders. Network especially in Windows, because VirtualBox shared folder for Windows is in network.
Wher can I get examples?

Thanks.
In Linux , DVD and USB drives are usually mounted in /media but how read true mounting points?
In can't find how to read network dirs in Windows, probably I must use SHGetDesktopFolder.
Here is piece of very old my Delphi code: (about SHGetDesktopFolder but not related to networks)
Code: Pascal

ImageListHandle
;
{ SendMessage(ListView.Handle, LVM_SETIMAGELIST, LVSIL_SMALL, ImageListHandle);
ImageListHandle := SHGetFileInfo('C:\',
0,
FileInfo,
SizeOf(FileInfo),
SHGFI_SYSICONINDEX or SHGFI_LARGEICON);
SendMessage(ListView.Handle, LVM_SETIMAGELIST, LVSIL_NORMAL, ImageListHandle);}

Hi!
In Linux you can read all mounted drives from
/proc/mounts
This is reaonly! And a loafFromFile will fail - read it one string after another!
The mountpoint for external drives is different in different distros.
It may be also /run/media
