Notes about the DFB file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The DFB file type is primarily associated with 'Data Flask' by Interscape. Data Flask is a spreadsheet application designed to retain data type, source, and key information. Information imported into a Flask Grid File (*.DFG) becomes an independent, disconnected copy of the data from the source. Data from a wide variety of sources is supported, ranging from Unicode text files to SQL databases. There is a free viewer available; look for the link on the program's site. VBScript is used for spreadsheet cell formulas.
