- other than your Home folder /home/your_name/ (~), you may want to put thing in a custom folder, like D:/ drive in your windows system,
- As you know, Linux / root directory is like your C:/ drive, all system folders are there and not for your to change (aka Filesystem Hierarchy Standard (FHS) for linux)
- those system folders are very short-named for faster typing on old slow computers 40 years ago

USB capacity varify

- test write and read on flash mount directory
f3write /media/username/flash_drive_label_name # after done, f3read /media/username/flash_drive_label_name
check USB device name
- list device name and mount point
lsblk
- list mount point
mount
- check device plugin notice
dmesg
Write ISO to USB
- check sum for verify file corrupt
sha256sum linux_os_disk.iso
- then search online for verify the sum code is same as online provided one
- umount usb
umount /dev/sdb1_like_part_name_for_usb
- write
dd if=linux_os_disk.iso of=/dev/sdb_like_device_Disk_name_check_above
- if you got error when boot that finished usb like “isolinux.bin missing or corrupt”, means you had dd into its partition with a number instead of sdb_name_like device. use lsblk again to see the name for the DISK or PART
