What is a DTF file

DTF files mostly belong to Symantec Touchbase. DTF files are not a single file type but a grouping of file formats used by several programs to store or transport data.

Symantec Database: Some DTF files, for example, hold a Symantec database used in Symantec Touchbase.

Data Transport: Others serve as transport files, such as the QuoteWerks data transport file (QuoteWerks).

Weather Data: Certain files store HOBO weather data from sensors managed by HOBOware (HOBOware).

AS400 Transfers: Some are used for data transfers from AS400 systems, including those from IBM iSeries.

Document & Image Formats: In some cases, the DTF extension is applied to files that hold PDF text (openable with Adobe Acrobat Reader, Adobe Reader) or PNG images (linked with Microsoft Office, Microsoft 365).

Microsoft and Other Proprietary Files: There are also instances where DTF files store data for Microsoft Excel (using Microsoft Compound files), Access (Jet database files), zipped Word templates, Exchange delivery notifications, or even schematic data in tools like ISIS Schematic Capture used in Proteus Design Suite.

FilExt.com tip: A quick look at the file’s header or metadata can reveal which internal structure (like UTF-16 (LE) or a compressed format) is used, helping choose the right software to open it.

How to open DTF files

You need a suitable software like Symantec Touchbase to open a DTF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DTF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DTF file directly in the browser:.

DTF file format details:

Every file has a defined file format, i.e. how the data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So you need a detailed analysis of a file to find out the format and the associated program. Below you will find our evaluation of the DTF files:
