Thank you, I think I got it.
TO HOME NETWORK SHARE FILES INSIDE YOUR OWN HOME WIFI ACROSS YOUR OWN PCS:
IF YOU ARE on your own home WiFi &
IF YOU want to share your files among your PCs (ie Desktop and laptop etc.)
On BOTH YOUR PCs (ie: your desktop, your laptop, to share your stuff)
First off, you must tell Windows 11 you want to SHARE A DRIVE
To share a drive in Windows 11, you can:
Right-click the drive you want to share
Select Properties
Go to the Sharing tab
Click Advanced Sharing
Check the box that says Share this folder
Click Permissions (you get full permissions for your own stuff)
Select 'Everyone'
Click on full control (read, write, delete) permissions
Click Apply and OK to save the changes
THEN WIFI SETTINGS ON BOTH DEVICES
Make sure both PCs are using the SAME Wifi (such as 2.4ghz or 5ghz)
To change a Wi-Fi network to public or private
Select Start,
then type settings.
Select Settings >
Network & internet > Wi-Fi.
On the Wi-Fi settings screen,
select Manage known networks, and
select the network you're connected to.
On the Wi-Fi network screen,
to share your own files among your own PCs in a private network,
select Private
Open CONTROL PANEL
Click on Network and Sharing Center
Click on Change Advance Sharing settings.
Click these to ON POSITION
* Set up network connected devices automatically
* file and printer sharing
pull down All Networks
* Turn OFF Password protected sharing
Now you can COPY/PASTE files or directories between your devices.
Personally,
I like to do my 'best/most current' work on my desktop
I like to clone selected desktop directories to my laptop
I personally like the SYNCBACK App to MIRROR Desk->Laptop
SyncBack
Whew!
Microsoft makes this so techie hard for regular people.
AND
I should have reminded everyone when you are finished sharing
data across your computers, be sure to UN-SHARE THE FILES/DRIVE.
(On both computers you had home networked)
Click on
This PC, then
The drive or directory you had 'shared', then
Give Access to (the drive or directory you shared)
Advanced sharing
Unclick (white box) 'share this folder'.
Apply & close.
You do want your data protected, not exposed to unknown persons.
Stay safe!
