Classic Shell: Forum

I cannot figure out how to get to C:/ to find files inside a software package using Windows 10. And/or using Classic Shell. I need to add some things to one of the files within the software Adobe Photoshop Elements 14 and I cannot get the computer to let me into it.Actually , I cannot even find where the innards of the software lives anymore. Where did they hide it and how can I access it as I always have in the past? I need to be able to access the presets folder so I can add some items to custom shapes, etc..
This is making me CRAZY!!!:x

Thanks so much. I hope someone can help me...I am considering throwing the computer through the window but that wouldn't really help...would it?

The easiest way:
Hold the windows key down and press the E key: [win]+e
From there type C: into the address bar at the top

Through the default start menu:
Hit the start button, and go to "File Explorer" on the bottom left corner

Through Classic shell:
right click the start button, and select 'windows explorer'
OR
Depending on what style/setting Look for 'My computer' or 'This PC' after left clicking the start menu
