On files on C drive, chmod 600 works as expected.
My workround for jupyter changed : export JUPYTER_ALLOW_INSECURE_WRITES=true => export JUPYTER_RUNTIME_DIR=/cygdrive/c/Users/user/AppData/Local/Temp (/cygdrive/c/Users/user/AppData/Local/Temp "tmp" environmental variable value in my current environment.) For another usb drive, chmod works as expected. chmod does not work => FAT32 chmod works => NTFS I back up all files to the external HDD and format FAT32 drive to NTFS drive and back them. Thanks!
