I am having a hard time trying to check if my MP3 player is connected
to the USB port of the computer. I don't know where to check. It
shows in "My Computer" as opposed to a hard drive. It shows as
"SanDisk Sansa c150" in "My Computer" and doing a search shows it also
in "Portable Media Devices" I tried using the FileSystemObject's
FolderExists function but it always hits the "Else" clause. Is there
anyway to check for items in the "My Computer" area?

This doesn't work. I tried it with the player both connected and
disconnected, and it always hit the "Else". Please help!

If fso.FolderExists("My Computer\SanDisk Sansa c150") Then
MsgBox "MP3 Player is connected"
Else
MsgBox "MP3 Player not found"
End If

Don't have a SanDisk MP3 player myself. Does it show up as a disk drive?
I.e. "F:\SanDisk Sansa c150"? If so, it's probably added as a flash drive.
Try enumerating the disk drives (GetLogicalDriveStrings and GetDriveType API
functions). Try enumerating them backwards, as flash drives are typically
added to the end of the list.

Thanks for the reply. I tried using the GetLogicalDriveStrings API like
you said, and it only shows drive letters. It won't show
non-drive-letter items. If you plugin a digital camera, MP3 player,
etc, they appear in "My Computer" without an associated drive letter.
Are there any other ways or API's that you can suggest that may work.
I really want to create an app to manage the files on my MP3 player,
but I can't even find the player using code, so I'm kinda stuck.
Please help me think of a way to find the player. If someone has code
that finds a digital camera in "My Computer" then please let me know,
because it may be the same code to find MP3 players.

Thanks,
Sincerely,
Pulling-my-hair-out-going-insane.

Tried GetVolumeInformation ? The volume name may show up the drive.

something like: (aircode)

dim s as string * 1000, ss() as string
dim i as long
dim sVolume as string * 100, sFileSys as string * 100, flags as long
dim serial as long

call getlogicaldrivestrings(1000,s)
i = instr(s,chr$(0) & chr$(0))
if i then
s = left$(s,i-1)
endif

ss = split(s,chr$(0))
for i = lbound(ss) to ubound(ss)
getvolumeinformation ss(i),sVolume,100,serial,0,flags,sfilesys,100
debug.print ss(i), ctrim(sVolume),serial,ctrim(sfilesys)
next

You may also want to throw a GetDriveType in there somewhere to cut
down on the unwanted ones.
Btw, as far as i know, all disklike devices will get a temporary drive
letter, even if MyComputer may not show it.
