Unable to perform file transfert from pyboard

rshell 0.0.28 Windows 10 , driver : microsoft usbser.sys Board : Pytrack (lopy4) , Pycom MicroPython 1.18.2.r7 Each time i try to get file from lopy i'm facing an error (exception) I can do repl, list my file with size (ls -l) but i was unable to do file transfert, each time i got, i have already try to run rshell with '-a' but without more succes Have you any idea how i can solve this issue ?
