How to use PST Walker

Basic Functions

After installing PST Walker, locate a Microsoft Outlook .pst or Microsoft Exchange .ost file on the hard drive of your PC.

You have two options when opening a file: "Like Microsoft Outlook" and "Extensive Scan". The extensive scan option will allow you to recover data from a damaged or a corrupted file but takes longer to load depending on file size. Try both options and compare.

PST Walker also lets you save any attachments that are on your emails. Select the email of your choice that has an attachment you wish to save, and select "Save Attachments" from the "File" menu button. Attachments can be opened by double-click as well.

Search Function

Having all of your email available isn't really worthwhile if you can't find what you want. Fortunately, PST Walker has a great search function.

Input the search query you want in the search box and click "Enter". In the example used below, "March", was used in the search field. After the search is performed, only matching entries are displayed.

Examples:
Using AND narows a search by combining terms; it will retrieve emails that use both the search terms you specify, as in this example:

  • July AND "Discount *%"

Using OR broadens a search to include results that contain either of the words you type in.

  • July OR August

Using NOT will narrow a search by excluding certain search terms.

  • NOT July

You can always combine multiple search strategies to focus your search to ensure that you find just the emails you want. Here are some examples of more complex searches.

  • (July OR August) AND Discount
  • July AND NOT Discount

Export Function
