Hi Kavam
I am Dave, an Independent Advisor, I will help you with this . . .
It depends on a few things, like what type of Apps you are downloading and installing
1
If those are Microsoft Store Apps:
Open the Settings App (gear icon on your Start Menu)
Go to System - Storage and click Change where now content is saved'
That will allow you to re-direct Store Apps to your D drive
Also, for Apps already installed from the Store, in the Settings App, go to Home - Apps, select an app and see if there is an option to Move the App
2
For 3rd party applications, some installers will allow you to choose a different install location, and some will not, you should see the option, if it is available, when you start the installer, if there is a 'Choose Installation Location' option
3
A further option is to move all your User Library folders to D:
Open Windows File Explorer
In the right hand pane, right click your Documents folder and choose Properties
Select the Location tab
In the Location box, type D:\Documents then click Apply and Ok
When that move completes, do the same for Pictures, Videos and Music
Each time, provide a new folder location, for example, Pictures will go to D:\Pictures
