DTF is a file extension for a database file used by ACDSee. DTF files contain a database of thumbnail images used by ACDSee. DTF files and their associated DDF files can be deleted if ACDSee is responding slowly. DTF files are used by ACDSee but aren't directly viewable with the application.

The DTF file extension is also used by Symantec Q&A relational database files and PFS Q&A database files.
