Restoring Personal Folders after reloading Windows 7

I had to reload Windows 7, and made a backup copy of my hard-disk before restore. When I reloaded the backup files, most went well, but some of the .pst files took an extra effort. BUT 7 years of personal folders were nowhere to be found! The backup file is about 58 zipped folders of 200 MB. How can I look up for my personal folders in this backup? Adress book, sent items and some other folders I have recovered, but all my saved e-mails (sent and received) are lost or at least disappeared. Any suggestions?

My home PC (Windows 7 Pro 32 bit) crashed and I had to reload the software. In the the process I was unable to recover some of my private folders on MS Office (2007 Pro). I now have the backup on a memory stick, and tried to restore the files on my laptop (Windows 7 Pro 32 bit, Office Pro 2010). The problem is that the recovery program only allows recovery from the back-up or from Internet. There is no (apparent) way to choose the memory stick for your backup. Any ideas how to do this?

I am also having problems in restoring Personal Folders after reloading Windows 7 and I would be grateful for some advice.

Following a re-load of Windows 7 all my data restored ok but not the PST file. After a couple of attempts to restore to the original location I tried restoring the AppData folder only, which contains the PST, to another folder on the C drive. Although the Restore facility confirmed it being restored and the properties showed the new folder to be of considerable size, it appears to contain no data. How do I make this 'hidden' data visible so I can restore my PST file from Outlook?
