How to get the free space values of disk drives

[M203]

Hi,
i want to send information about available space on my three drives on my desktop (win 7) to my android devices.

So the trigger will be directory watcher noticing a file has been added, then I need the remaining space of that drive and send the value to my android devices.

So trigger is directory watcher and I send the data/values regarding remaining free space with Autoremote plugin for Eventghost but how do I get the disk space information?

Thanks
Peter

Why do you not ask Uncle Google? He finds everything.
I did it and I got a page Disk usage (Python recipe).
I've tried it - it works.

Thanks!

I dont now where (python plugin?) to put the code or do I even know python. I do have friends who know python so hopefully they can help. And I guess I will have to search this site for documentation. Hopefully it i'll work out in the end. Thanks for the code!

Just copy & paste the below into a python script and execute it

Thanks Pako and Krambriw, the code you provied solved it. However, I ran into another problem.

I added a directory watcher and created a folder and dragged the event to my macro, added a python script with the code and finally an autoremote action to send the value to my android device. I execute the macro and it works fine all the way.

However I got an error message when saving my config. Also, I already have a couple of macros that have been running for a while now which wasnt a problem to save (sending message via autoremote to android when pc turns on / off. So I reloaded my working config and only added the directory watcher to my existing config and tried to save. I got the same error message as when trying to save the complete "send free disk to android" macro, please see below. What can be the problem? The log starts from where I added the directory watcher. The error indicates issue with autoremote but it has been fine to save before and the issue starts when adding just the directory watcher and then I try to save.
