Under Win8, the newly added Metro application can only be installed on the system disk by default, causing the system disk to become bloated and not seeing the installed program and its size in Control Panel-programs and features.
How to view Metro Application size:
Win+c Open Charm (Super button), select "Settings", select "Change computer Settings" in the lower-right corner, and select "General" to find "View application Size" under Available storage.
How to view the Metro application installation location:
Metro applications are installed under "%systemroot%program Fileswindowsapps (hidden folders)" To open the need to add account capture permissions.
Right-click the "Windowsapps" folder, select "Properties", select the "Security" menu, click "Edit"
Add "Everyone" account: Enter "Everyone" in the input box, click "Check Name", as shown, underline, click OK.
Open the Windowsapps folder.
File naming is messy after opening, for example, "Renren" has a folder named:
"359109E9. Hd_220.127.116.11_neutral__cc3c5k7dgdn90 "
To locate the folder, open the application first, and then open Task Manager, locate the running program, and right-click properties.
You can see the name of the folder in the general, (you can also open the location if you have permission to choose "Open File Location").
Alternatively, you can open "Windows PowerShell" in "All Programs" and enter "Get-appxpackage" to view version information, folder location, and so on for all programs under the Metro interface.
Locate the program's name (name), and "Packagefullname" is the folder where the program resides. In addition, you can see the version of the program.
