.EDB File Extension

Database created by Microsoft Exchange Server; serves as the main repository for the mailbox data saved by Exchange; stores both in-process and stored non-SMTP messages; formatted using a b-tree structure, which includes a top-level node and many child nodes.

Priv1.edb and Pub1.edb are the main EDB files used for the Exchange information store. They each have a corresponding .STM file that contains SMTP messages.

An EDB file is a database file created by the Windows Search feature included with Microsoft Windows. It contains indexed information about files that have been searched for in the Windows Search feature. EDB files allow the search feature to more quickly return results about files that have been previously searched.

EDB files may grow large in size, up to several hundred gigabytes (GBs). You can delete the EDB file on your computer to free up space on your hard drive. However, doing this will erase the indexing

You can find the EDB file in the following location:

C:\ProgramData\Microsoft\Search\Data\Applications\Windows\
