I've enabled the SSH server in my Raspberry Pi. I'm using WinSCP to SFTP files to and from it. I'm testing it with a USB flash drive mounted at /mnt I've used chmod to set /mnt permissions at 777.

I can use a remote computer to access pi and copy files from /mnt to c:\testlocal. This works with WinSCP.

Quote:
option batch on
option confirm off
open pi@mydomain.duckdns.org
option transfer binary
get /mnt* c:\testlocal\*
synchronize local c:\testlocal mnt
exit


But going the other way, it acts like it can't access /mnt. This doesn't work:

Quote:
option batch on
option confirm off
open pi@mydomain.duckdns.org
option transfer binary
put c:\testlocal\* /mnt
synchronize remote c:\testlocal mnt
exit


If I use a folder such as /home/pi/testremote it does work, just not at /mnt.

Where is it going wrong? THANKS in advance for the help.

Here's the relevant log file info:

One clue why it may not work is in the log file , eighteen lines from the bottom.

It seems to think the USB drive is mounted at home/pi/mnt. But it's not. It's mounted at /mnt .

What needs to happen to make it look at /mnt and not /home/pi/mnt?

The problem has nothing to do with USB. It's that your path syntax is not correct.

It should be:

get /mnt/* c:\testlocal\*

See https://winscp.net/eng/docs/scriptcommand_get

put c:\testlocal\* /mnt/ or put c:\testlocal\* /mnt/*

See https://winscp.net/eng/docs/scriptcommand_put

synchronize remote c:\testlocal /mnt
