Opening HDMP files
Did your computer fail to open a HDMP file? We explain what HDMP files are and recommend software that we know can open or convert your HDMP files.
What is a HDMP file?
Files with the .hdmp extension usually contain uncompressed error dump files. These files are created by the Windows XP and Vista operating systems when an application crashes or encounters a critical error. The HDMP files contain a "dump" of the program state, showing the state of the program when the error occurred. These files are often sent to Microsoft as a part of the software debugging process.
Software that will open, convert or fix HDMP files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
