I inserted usb stick in raspi.
But how do i open filename in usb drive?
I can see USB Drive in File Manger.
Try:
mount -a
root@supra:~# mount -a

Is there something wrong on diet-config or diet-software?
Could be an issue with the drive. It could also be already mounted as ext4.
Can you try the following:
df -h | grep usb_1
ls -lha /mnt/usb_1
cat /etc/fstab | grep sda1
blkid
It may also be worth sending me a bug report so I can check your system setup and settings:
dietpi-bugreport
No need to fill out the text document, just reply with your reference CODE:.
root@supra:~# df -h | grep usb_1
root@supra:~# ls -lha /mnt/usb_1

Your are using a FAT based filesystem, so we need to change the mount settings:
- edit /etc/fstab
- comment out all /dev/sda1 entries (eg: #/dev/sda1)
- Add the following
/dev/sda1 /mnt/usb_1 vfat defaults,noatime 0 0
- run mount -a
Thank you very much. 
I can see files in usb stick.
Thank you so much.
