File extension .HDX

| Delphi MultiHelp Index Format | Autodesk | Misc Files |
The HDX file extension is associated with the Delphi programming language and is an index file created by the Delphi MultiHelp tutorial system. MultiHelp requires the creation of additional files that include all of the topics, search strings, keywords, index information and descriptions necessary for it to build a comprehensive help system. The HDX file is the index file that contains all of the topics, keyword and search strings for Delphi's help system. When you view the help within a project window, Delphi accesses this file in order to display the appropriate help topic.
Overview
The HDX file stores a massive amount of unparsed and compressed information into a binary format. This information includes detailed instructions for navigating through Delphi's help system and the program itself. HDX files are used to initialize and accelerate help systems within Delphi projects. They are also used to create full-text indexes for basic and advanced database or document searches.
Similar Formats
HDX files are similar to other index files such as the GID , SDF , LTX , FTS , WRI , AIDX , ALI , IXB .
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .HDX) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .HDX extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .HDX file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .HDX extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .HDX extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .HDX file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .HDX file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .HDX file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .HDX file) will be extended to the maximum.
It is also good to check
- if the .HDX file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
