Opening TDB files

Did your computer fail to open a TDB file? We explain what TDB files are and recommend software that we know can open or convert your TDB files.

What is a TDB file?

The TDB file format is most commonly associated with the ACT! and Thumbs contact management system database applications. These TDB files contain the settings that determine how the contact management software runs and stores the information that is saved for each contact.

The .tdb file extension is also used for the database files that are created by the SlamDB database application and files that are created by the eBay Turbo Lister. The eBay Turbo Lister allows eBay sellers to upload their listings more quickly to the eBay website. The TDB files that are created by this software contain backup files for the eBay Turbo Lister.
