What is an ADF file?

An ADF file is a database file created by ACT!, a customer relationship management (CRM) application. It contains customer contact data such as names, email addresses, business information, and the relationship history. ADF files are used for customer relations information in a structured format.

More Information

ADF files are saved with an .ALF lookup file, which contains metadata required to navigate, backup, and restore the ACT! database. ADF files may also be archived within ACT! database backups, which use the .BAK extension. ADF files use Microsoft SQL Server formatting and are similar to .MDF files.

NOTE: Sage ACT! became Swiftpage Act! in 2013.

What is an ADF file?

Internal raster data format used by ESRI products such as ArcGIS, ArcView, and ArcInfo Workstation; stores spatial data as a binary grid (rows and columns of cells) and is one of several ADF files that together comprise the total grid; used to represent geographical or other spatial objects such as maps and map features.

More Information

An ArcInfo binary grid can contain multiple raster layers, forming a layer stack. This can be used to overlay different views on surfaces and perform statistical analysis on the spatial data.

ADF files can store metadata about the raster set or actual raster data. When you create a binary grid, the files named dblbnd.adf, hdr.adf, sta.adf, vat.adf, and w001001x.adf provide metadata about the raster grid, while the file w001001.adf contains the actual raster data. These files are typically separated out into their own folder so that they are easy to manage as an entire grid coverage set.

ADF files may be used to store a variety of model types, such as organizational charts, data models, whiteboards, system landscapes, process landscapes, business processes, and IT infrastructures.
