ADF database files are most widely known as ACT! Data Files used by the ACT! customer relationship management (CRM) software to store structured customer and relationship data. The ADF format is designed to hold contact data, business details, and ongoing relationship history in one place, giving the CRM software a fast way to retrieve and update customer records. In many modern installations, the ADF file works in conjunction with a separate log or support file, yet ACT! presents it as the primary database, handling all low-level storage details behind the scenes. As a closed, application-specific format, the .ADF extension should be regarded as an internal ACT! database container that only ACT! or specialized utilities should open and alter. When the original ACT! installation is unavailable, tools like FileViewPro can still recognize the .ADF extension as belonging to an ACT! CRM database, show non-destructive details, and help you decide on the best way to recover or convert the data.
Behind nearly every modern application you rely on, whether it is social media, online banking, email, or a small business inventory tool, there is at least one database file silently doing the heavy lifting. At the simplest level, a database file is a structured container that stores collections of related data so software can save, search, update, and organize information efficiently. Instead of being free-form like ordinary text files or spreadsheets, database files follow defined structures, use indexes, and enforce access rules so they can manage huge volumes of records with speed and stability.
The origins of database files stretch back to the mainframe computers of the 1950s and 1960s, when companies first started converting paper files into digital records on tape and disk. These early designs were usually hierarchical or network-based, organizing information into parent-child relationships joined together by pointers. Although this approach worked well for very specific tasks, it was rigid and hard to change when business requirements evolved. A major breakthrough came in the 1970s when Edgar F. Codd at IBM proposed the relational model, which stored data in tables of rows and columns and relied on mathematical principles to define relationships. Codd’s ideas inspired generations of relational database products, including DB2, Oracle, SQL Server, MySQL, and PostgreSQL, and each of these platforms relies on its own database files to hold structured, SQL-accessible information.
With the growth of database technology, the internal layout of database files kept evolving as well. In early implementations, most of the tables, indexes, and catalog data lived side by side in large, tightly controlled files. Later generations started dividing data structures into multiple files, isolating user tables, indexes, transaction logs, and temporary storage so they could be tuned more precisely.

At the same time, more portable, single-file databases were developed for desktop applications and embedded devices, including formats used by Microsoft Access, SQLite, and many custom systems created by individual developers. Whether or not you see them, database files are responsible for storing the data behind accounting packages, media collections, customer lists, POS terminals, and many other programs.
When database architects define a file format, they have to balance a number of competing requirements and constraints. A key priority is ensuring that information remains consistent after crashes or power outages, so most systems maintain transaction logs and recovery data alongside their main database files. Another challenge is supporting concurrent access, allowing many users or processes to read and write at the same time without corrupting records. Within the database files, indexes function as smart roadmaps that point queries toward specific records, dramatically reducing the need for full-table scans. Depending on the workload, database files may be organized in columnar form for fast reporting and data warehousing, or in traditional row-based layouts focused on rapid transactional updates and integrity.
The role of database files extends into many advanced domains that require more than just basic storage of customer lists or inventory tables. When used in data warehousing and BI, database files consolidate historical data from many systems, giving analysts the foundation they need to explore trends and plan for the future. In geographic information systems, specialized database formats store maps, coordinates, and attributes for locations around the globe. Scientists and engineers employ database files to preserve lab measurements, simulation data, and sensor streams, making it possible to search and cross-reference very large datasets. Even modern “NoSQL” systems such as document stores, key-value databases, and graph databases still rely on underlying database files, although the internal structures may look quite different from traditional relational tables.
The evolution of database files reflects the industry’s shift from single-machine storage to distributed and cloud computing environments. Historically, one database file or set of files would sit on a single host machine, whereas modern cloud databases break data into segments replicated and spread across many servers. Even so, each node still writes to local files at the storage layer, sometimes using log-structured designs that append changes sequentially and then compact data later. Modern database file layouts are frequently shaped around the behavior of SSDs and networked storage, minimizing random I/O and capitalizing on parallelism. Ultimately, no matter how sophisticated the surrounding infrastructure becomes, the database file continues to act as the persistent foundation where data is permanently stored.
The sheer number of database products and use cases has produced a matching diversity of database file types and extensions. Certain database file types are openly specified so other software can read them, but many are proprietary and designed to be used only by the original application. For users, this variety can be confusing, especially when they discover unfamiliar database files on their systems or receive them from colleagues, clients, or legacy software. Depending on the context, a database file might be an internal program component, a self-contained data store that you can browse, or a temporary cache that the software can safely rebuild.
As technology advances, database files will keep evolving, becoming more streamlined and better tuned for specific workloads and environments. Newer designs focus on stronger compression, faster query performance, better use of memory, and more robust integrity guarantees in distributed systems. Because companies regularly migrate to new platforms, merge databases, and integrate cloud services with local systems, tools for moving and converting database files are more critical than ever. In this environment, utilities that can open, inspect, and sometimes convert database files are extremely valuable, especially when documentation is limited or the original application is no longer available.
For everyday users, the most important thing to understand is that database files are not random blobs of binary data but carefully structured containers designed to balance performance, reliability, and flexibility. This careful structure means you should not casually change database files by hand; instead, you should back them up and access them through software that understands their format. Tools such as FileViewPro aim to recognize a wide range of database file extensions, give you a way to view or inspect them where it is safe to do so, and show how they fit into your overall workflow. From occasional users to IT professionals, anyone who knows how database files function and how to interact with them is better prepared to protect, migrate, and make use of the information they contain.
