What is an HDMP file?
A .HDMP file is an uncompressed Windows Heap Dump. The Microsoft Windows operating system creates this file when an application crashes or encounters a fatal error. The Windows Error Reporting system generates the .HDMP file to record the exact memory state of the software at the moment of the crash. Developers use these files to find bugs and fix software problems.
How to open HDMP files?
Natively, developers open .HDMP files using debugging tools like Microsoft Visual Studio or WinDbg. Because these are large binary files, standard text editors will not display them correctly. If you do not have development tools installed, opening these files can be difficult.
Best practices and troubleshooting
Because .HDMP files contain uncompressed memory data, they can take up a large amount of disk space. If you are not a developer and do not need to debug a crashed application, you can safely delete these files to free up storage.
Software and tools
viewer.online/hdmp can analyze .HDMP files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
viewer.online/hdmp is highly useful for identifying, inspecting, and understanding .HDMP files without installing software or dealing with compatibility problems. While .HDMP generally refers to a Windows Heap Dump, it can have multiple possible meanings; we recommend using viewer.online/hdmp to identify the actual format of your file.
