<p dir="ltr">Linux uses a single filesystem hierarchy. Everything is under / (even removable or network drives). When you created the folder and mounted the flash drive to /mnt/usbflash you were telling the OS that your flash drive can be found at /mnt/usbflash. Without mounting it, Linux can't see it, since it isn't in the file system hierarchy. Does that make sense?</p>

Is the folder on the OS, a hardware abstraction queue?<br>

While i'm out tonight wearing my ignorance on my shoulder, i
was wondering if someone could provide an explanation of how
the below works.<br>
<br>
On a VMware server running Centos, i needed to copy some sql
data onto a flashdrive. Once the USB host and device are
attached to the VM,<br>
in order to be able to write to the flashdrive i:<br>
<br>
fdisk -l and got the "sdc3" that i needed<br>
<br>
But i just don't understand enough about the OS to know how
the below mounting works. Why writing to the "usbflash"
magically shows up on the flashdrive is a mystery to my brain.<br>
<br>
mkdir /mnt/usbflash<br>
cp tmp/asdf.sql to the usbflash directory i just created<br>
mount /dev/sdc3 /mnt/usbflash<br>
<br>
P.S. Above is from memory of earlier in the day so hopefully
is accurate<br>
