Now a PS drive is a data store location, or in simple words, I can say
it's an entry point to access this specialized data store just like you
would access files and folders of the system.
If you have worked with PowerShell, then at some point in life you might have
used Get‑Item or Get‑ChildItem command to get list of files and folders from
any of the system drive. The command below retrieves all the files and folders
present in C:\Windows\System32 folder.
It is easily understood that the command will fetch files and
folders that resides on the C drive. Now this C drive is a PS
drive that belongs to file system provider.
This C drive acts as an entry point to access everything
that exists in C drive. Similarly,
each partition on the drive has its own PS drive,
so if there are more partitions like D, E, and F, each of
this partition will have its own PS drive using which data
of each drive can be accessed.
This was about file system partition.
Likewise,
there are other PS providers and each PS provider has one
or more PS drives, or in other words, entry points to its data store.
The technique to access data from the data store will be same, that is PS
drive followed by the complete path of the data store.
You can get complete list of PS drives by running Get‑PSDrive command. You can also create custom PS drives which we will see in upcoming modules.
