What is an HLD file

HLD files mostly belong to Hysitron HighLoad FBControls.

These HLD files are Hysitron indentation data files that store detailed results from nanoindentation tests. They capture load and displacement measurements during material indentation and are designed for analyzing mechanical properties.
The data is processed using the Hysitron HighLoad FBControls software and is integral to computing values such as hardness and elasticity. The format preserves raw testing curves along with embedded metadata for precise scientific evaluation.

Key details compiled by FilExt.com include:

Indentation Data: Records force and displacement information from nanoindentation experiments.

Precision Metrics: Contains embedded metadata useful for advanced material property calculations.

Proprietary Format: Requires dedicated Hysitron software for proper viewing and analysis.

How do you open HLD files?

You need a suitable software like Hysitron HighLoad FBControls to open an HLD 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 HLD file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a HLD file directly in the browser:. Just drag the file onto this browser window and drop it.

HLD file format details:

If you know the file format, you can also find out how to open or edit the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the HLD files is as follows:

HLD is rarely used as a file extension and does not have a uniform file format. The two most common formats are as follows:

• 15% of all HLD files use the same file format, which have the signature File Version: Hysitron HighLoad FBControls 6.1 Release. These files are text files, so they contain words and text. The average file size is 460 KB with most files being between 87 KB and 2 MB in size. Several words can almost always be found in the files, e.g. File Version: Hysitron HighLoad FBControls 6.1 Release, Test Humidity: 50 %, Test Temp: 23 deg C, Test Type: Indentation, Time Stamp, Stage X: -1000 mm and Stage Y: -1000 mm. Such files are related to buffer.
• 10% of all HLD files are based on the Microsoft Compound File format, also known as Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. This Windows file format has features similar to those of a filesystem format with virtual files and subfolders. Header signature for the CFB format with 8-byte Hex value D0CF11E0A1B11AE1 (which looks like "DOCFILE"). There is also a globally unique identifier 7559fd90-9b93-11ce-0000-000000484c44. Sections and streams in the file are named Contents. A typical file size is 28 KB.

The remaining 75% of all HLD files are files with no common format, the following 5 formats can be found: ZIP and version. Sometimes used for audittrail or holdings. If you want to find out which format your HLD file belongs to, just click on the button "Choose your .hld file to analyze".
