App Data question

Windows 10 has gotten real picky about what it will let you do. In order to change the location of a system folder that doesn't have the location tab can be catastrophic and could result in a clean install of windows. You can try reinstalling the program or programs and if they have an option to choose a different directory for the installation I'd go that route and see how it goes.

Wayne,

Whatever you end up doing, I urge you to use Treesize [free] to measure the space taken up by folders. Windows does not give accurate results for many folders, particularly ones within C:\Windows.

Best of luck,
Denis

Note that using the Location tab is fraught with danger. If you use it correctly, fine. Make one mistake and you have a close to unrecoverable mess.

Personally I'd never take that risk: note the tutorials on using the Location tab urge you to create a disk image first. (And you are strongly advised to use that routinely anyway to give you a second chance and a full backup).

I found that the appdata file that had gained the most was the "Local" I plan on moving my Roaming folder to my D drive but the "Local" folder does not have the "location" tab to move it

You can move your whole user profile folder (which includes those) to another disk, but there are risks- this is not straight forward.

A good strategy is to keep as much personal data off C: as possible.

Try Ccleaner maybe?

Use "Analyze" button to see what would be removed. You need File List for that:

Do a preview clean - "Analayze"

Also if you've uninstalled software using windows uninstaller instead od a decent uninstaller there might be folders left in appdata for removed software. If you can identify any then you can delete them.
