available space on disk and delete logs

Hi Experts,

I think this is the right place to put the question. I need your help, I am studying powershell but I am having difficult to write the script with powershell. I have not enough skills.

I would need a powershell such as:

- It will be launch from  my workstation or server of my domain providing administrattors credential in other domains to be able to execute command there.
- The goal is to get:
* To get information about differents hard disk units on target server; total space in disk and free space available. (could have c,d,e,...) units. There is not a rule.
* Export that information to excel, creating the file iin the pc where the scrilpt is being launching (source pc in which I am launching the script). The name of the file is the same that the IP adress of the server where we are connecting to get information.
* In a specific folder on the target server check for files which are  contained into a specific folder and are two weeks old, the goal is delete them (are logs files). report the action in a logs indicating amount of deleted files and the size disk.

Please, I need the help of an expert, It is very important for me to be able to finish this task.
