.SYNOPSIS
|
||
|
|
Script that retrieves disk information from a list of computer and outputs to csv
|
||
|
|
|
||
|
|
.DESCRIPTION
|
||
|
|
This script reads a list of servers or computer from a plaintext file and read the disk information
|
||
|
|
using WMI. This information will be written to a comma-separated file containing the computer name,
|
||
|
|
drive letter, total space, free space and free space percentage. The log file automatically
|
||
|
|
generates a timestamp so this job can be scheduled as a task without overwriting the previous
|
||
|
|
log file.
|
||
|
|
|
||
|
|
.PARAMETER Listpath
|
||
|
|
The plaintext file containing
|
||
|
|
|
||
|
|
.PARAMETER Logpath
|
||
|
|
Optional parameter, if not filled in it will default to .\
