Little help needed setting up my cloud storage to mine Burst

So I found a way to map my Google Drive, OneDrive, Dropbox and my external that is plugged into my router so that they appear as a drive letter in "This PC" in Windows 10:

• "G:" is my Gdrive

• "X:" is my dropbox (for some reason drive and dropbox's sizes and free spaces got merged, but whatever I can deal with that)

• "N:" is my network external HDD plugged into my router

And sure enough, they all show up when I click "Write Plots" in my Burst wallet:

But I'm unable to plot any of them. G: returned an error:

and the other two didn't return an error or even open a cmd window, but all of them (Gdrive included) had a "Burst" folder in them after with these contents:

Any help getting these drives plotted would be much appreciated. Thank you!
