It’s Window7 machine’s hard drive. But I don’t have the confirmation about the version of MS Outlook. After exploring within folder I found Outlook folder at these location:
C:\Users\admin\AppData\Roaming\Microsoft\Outlook
C:\Users\admin\AppData\Local\Microsoft\Outlook\RoamCache
But at first location I found only .srs & .xml file
& at second location there were some .dat file
And after checking the size of these file I could understand that it couldn’t be the email storage of Outlook.
