Detect USB and copy *.* to USB drive using batch script - batch-file

Question

I am trying to write a batch script to detect a USB drive and, if it is plugged in,
for example copy c:\test\big.txt to the USB drive, and looping to detect another flash drive.

Answer 1

#echo off
for %%d in (D: E: F: G: H: I: etc...) do (
if exist %%d\nul (
echo USB at drive %%d connected
)
)
EDIT: Below is the right way to do that:
#echo off
for /F "tokens=1*" %%a in ('fsutil fsinfo drives') do (
for %%c in (%%b) do (
for /F "tokens=3" %%d in ('fsutil fsinfo drivetype %%c') do (
if %%d equ Removable (
echo Drive %%c is Removable (USB^)
)
)
)
)

Answer 2

I know this is old but....
#echo off
for /F "usebackq tokens=1,2,3,4 " %%i in (`wmic logicaldisk get caption^,description^,drivetype 2^>NUL`) do (
if %%l equ 2 (
copy c:\test\big.txt %%i
)
)
This is assuming of course both drives are inserted.

Answer 3

The above code had a flaw which has been attended to in the following code
The code works in XP and gives you the USB drive letters, if no usb device
is connected , it tells you so !

set usbletter=%%c
set usb=Yes
echo USB drive letter is %usbletter%

rem echo USB1 drive letter is %usbdrv%
)
)
)
del de
del dlist
echo REPEAT:Device at %usbletter%
if "%usb%"=="No" echo No USB Device Connected .
set usb=

#Aacini I don't have a good setup to this case today, so I instead tried finding my USB webcam. I used devmgmt.msc and devcon listclasses to figure out the membership a connected USB camera would have. After a few tests, I arrived at devcon find =Image USB\*. I figured it would be simple enough to do the same for a USB mass storage device, so I tried devcon find =Volume (per listclasses). Unfortunately, this dumps out a GUID which you would then have to map to a drive letter. A cursory glance at this overflow suggests you can do so from the registry using reg query, but it seems at this point that fsutil would be simplest for your case.
