In addition, it is compatible with a broad variety of platforms and applications for importing and exporting contact lists.

What are OST and vCard files?
OST files are Offline Storage Table files used by Microsoft Outlook to store offline copies of data from a user’s Exchange mailbox. These files contain email messages, contacts, calendar entries, tasks, and other data that can be accessed even when the user is not connected to the Exchange server. OST files are typically used in situations where users need to work offline, such as on a laptop or tablet.
vCard files, on the other hand, are a standard file format used to store contact information. A vCard file can contain a person’s name, address, phone number, email address, and other contact details. vCard files can be exchanged between different applications, devices, or web services that support the vCard format. vCard files are widely used in email clients, mobile devices, and web applications to import and export contact information.
Comparison between OST and vCard files:

- Outlook OST files are proprietary to Microsoft Outlook and can only be used with that software, while vCard files are a widely accepted standard for exchanging contact information.
