A PST file stores the entire Outlook attributes such as emails, calendars, contacts, etc. At times, it happens that the user may possess multiple PST files due to prolonged use of Outlook. These PST files can get hard to manage and at times may even lead to corruption if not managed properly.

Test Run of the Software

We did a test run on the software by running its demo/trial version. The trial version works in same manner as the license version. However, it limits the counts of items that it merges as compared to the license version. Some of the major features of the software are:

1. Add PST File/Folder

On the home page of the software, the user will get two options for adding the PST files for merging. The Add Files option will enable the users to add the PST files individually. On the other hand, the Add Folder option will add the entire folder containing multiple PST files.


2. Join option

The Join option will merge PST files into one common parent PST file. All the merge PST files will be visible as different folders present under the output PST file. The entire internal folder structure of all the PST files is maintained and no compromise is done with the data integrity of the PST files.


3. Merge option

The Merge PST files option is opposite to the join option. This option merges the common folders of all the input PST files and saves the data in a common folder. If 3 PST files are merged, their folders like inbox, outbox, etc. will get merged in a single inbox, outbox, etc. folder.


4. Merge Contacts option

As the name suggests, the option is only concerned with the contacts of the PST files. selecting this option, will merge all the contacts of the multiple PST files into a common contacts folder.


5. Advance Options

The software is also embedded with advance options for making the merging process more efficient. They are:

6. Remove Duplicates

This option removes duplicate items like emails, contacts, calendars, etc. from being merged in the resultant PST file.


7. Exclude Deleted Items

This option removes the items residing in the deleted items from being added to the resultant PST file. This option is only enabled in Merge & Join option and not in Merge Contacts.



  • 3 variant options for adjoining the PST files.
  • Advance options for additional provisions.
  • No compromise with the data integrity of PST files.


  • No preview of PST files before the entire process is finished.
  • No option to search for a particular item in the PST files.

The Verdict

On the basis, of the efficacious features and working of the tool, it will bag a rating of 9.6 from us. No doubt the software merge PST files and offers 3 merging options but it does not give a preview of the PST files before they get merged. It is both an efficient and robust tool that proves to be of great use for managing multiple PST files.
