	File type:	specialized database file

What is an HLF file?

HLF files mostly belong to HydraCAD. This file comes in two forms. The main type is a HydraCAD List File that uses the JetDB format to store hydraulic calculation data. It holds lists and values needed for hydraulic design.
Some files with the HLF extension use an XML structure. In these cases the file serves as a license file or a log file, for example as a Hitachi Log File in systems like Hitachi Content Platform.
Key details compiled by FilExt.com include:

Hydraulic Data: Stores data for hydraulic calculations.

Internal Format: Uses JetDB in the primary version, or XML in the alternate form.

Usage: Employed in specialized design software or system license management.

Related Systems: Linked with Standard Jet DB and SprinkCAD for the hydraulic version, and Hitachi systems for the XML version.

FilExt.com tip: To open such files, use the dedicated software that supports either the JetDB format or XML. A text editor might reveal XML tags if the file is a license file.

How to open an HLF file
