About HDMP files

An .hdmp file is an uncompressed heap memory dump generated by the Microsoft Windows Error Reporting system when an application crashes. It captures a complete snapshot of the application's memory at the exact moment of failure, primarily used by software developers to diagnose bugs and system faults. You must use specialized debugging tools like WinDbg or Microsoft Visual Studio to properly open and analyze these Core dumps. Standard users frequently encounter these files taking up massive amounts of storage space. Because .hdmp files are uncompressed binary snapshots, they suffer from severe disadvantages: they often exceed several gigabytes in size, contain sensitive user data left in memory, and are completely unreadable by standard text editors or web browsers. Users often need to convert or extract the stack trace data into TXT or LOG files to share diagnostic information with support teams without sending massive, sensitive binary payloads. Alternatively, compressing them into ZIP or 7Z formats is necessary for transfer. This file format is notoriously difficult to open or convert because it is a raw, unindexed binary map of system memory designed strictly for debuggers. Standard online converters fail to process it. However, you can drag and drop your file to see what it is and convert it if supported on convert.guru. We can identify the file format, inspect the binary file, and attempt to show embedded text strings or internal error codes. If our analysis detects extractable underlying text data, viewing or limited conversion may still be possible.

Convert.Guru analyzes your HDMP file, detects the exact format, and lets you read the text inside.

Users also converted SFCACHE, DMP and DLL files.

The HDMP Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HDMP converter.
