You can access the shared space folder in the following ways:
Clicking the 'Shared Space' shortcut on your computer desktop
Clicking 'Shared Space' button on the CIS interface
Opening 'Sandbox Tasks' from the Tasks interface then clicking 'Open Shared Space'
By default, sandboxed applications can access folders and files on your 'real' system but cannot save any changes to them. However, you can define exceptions to this rule by using the 'Do not virtualize access to...' links."

Now, if the files were indeed saved to that "shared space" folder, then you should start a file recovery application yesterday. The more you wait, the more files are being written randomly on your C partition, thus diminishing your chances of recovery greatly.
If you are using a TRIM-enabled SSD, then i'm truly sorry. Your data is unrecoverable.
Do you know any good file recover application? I guess I can try to run it on the open 'shared space'.
Qwizzie I am on the fucking Windows 8.
