HPROF File Extension

What is HPROF file?

Files with .HPROF extension can hold heap memory dump for programs running on Java virtual machine - JVM. Java Heap Dump files are generated using HPROF dynamically linked library. HPROF is a binary file format and can grow quite large, even up to several Gbin size. HPROF is a type of debug file and can be safely deleted without affecting program performance.

Generating .HPROF files

Files with .HPROF extensions are typically generated during Java memory errors. How HPROF files are created can be configured in debugging and tracing tools. Memory dump files may also be created automatically upon Java VM abrupt termination.

Contents of HPROF files - application memory issues

Java HPROF files can be analyzed with Memory Analyzer (MAT) tool co-developed by SAP and IBM. This simple GUI application can import HPROF files an analyze them for OOM (Out Of Memory) errors, variables settings, or as a means of optimizing application memory usage. Some other memory analyzers are available, for example Eclipse Memory Analyzer.

Programs which support HPROF file extension

The following listing features HPROF-compatible programs. Files with HPROF suffix can be copied to any mobile device or system platform, but it may not be possible to open them properly on target system.

How to open file with HPROF extension?

There can be multiple causes why you have problems with opening HPROF files on given system. Fortunately, most common problems with HPROF files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. The list below will guide you through the process of addressing the encountered problem.

Step 1. Get the Eclipse Memory Analyzer

Problems with opening and working with HPROF files are most probably having to do with no proper software compatible with HPROF files being present on your machine. The solution is straightforward, just download and install Eclipse Memory Analyzer. On the top of the page a list that contains all programs grouped based on operating systems supported can be found. The safest method of downloading Eclipse Memory Analyzer installed is by going to developer’s website (Eclipse Foundation) and downloading the software using provided links.

Step 2. Check the version of Eclipse Memory Analyzer and update if needed

If the problems with opening HPROF files still occur even after installing Eclipse Memory Analyzer, it is possible that you have an outdated version of the software. Check the developer’s website whether a newer version of Eclipse Memory Analyzer is available. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. If you have an older version of Eclipse Memory Analyzer installed, it may not support HPROF format. All of the file formats that were handled just fine by the previous versions of given program should be also possible to open using Eclipse Memory Analyzer.

Step 3. Associate Java Heap Dump files with Eclipse Memory Analyzer

If you have the latest version of Eclipse Memory Analyzer installed and the problem persists, select it as the default program to be used to manage HPROF on your device. The next step should pose no problems. The procedure is straightforward and largely system-independent

Selecting the first-choice application in Windows

• Clicking the HPROF with right mouse button will bring a menu from which you should select the Open with option
• Select Choose another app → More apps
• Finally select Look for another app on this PC, point to the folder where Eclipse Memory Analyzer is installed, check the Always use this app to open HPROF files box and conform your selection by clicking OK button

Selecting the first-choice application in Mac OS

• Right-click the HPROF file and select Information
• Open the Open with section by clicking its name
• Select the appropriate software and save your settings by clicking Change all
• If you followed the previous steps a message should appear: This change will be applied to all files with HPROF extension. Next, click the Continue button to finalize the process.

Step 4. Check the HPROF for errors

If you followed the instructions form the previous steps yet the issue is still not solved, you should verify the HPROF file in question. Problems with opening the file may arise due to various reasons.

1. Verify that the HPROF in question is not infected with a computer virus

If the HPROF is indeed infected, it is possible that the malware is blocking it from opening. Scan the HPROF file as well as your computer for malware or viruses. If the HPROF file is indeed infected follow the instructions below.

2. Verify that the HPROF file’s structure is intact

If you obtained the problematic HPROF file from a third party, ask them to supply you with another copy. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. If the HPROF file has been downloaded from the internet only partially, try to redownload it.

3. Ensure that you have appropriate access rights

Sometimes in order to access files user need to have administrative privileges. Log in using an administrative account and see If this solves the problem.

4. Check whether your system can handle Eclipse Memory Analyzer

If the system is under havy load, it may not be able to handle the program that you use to open files with HPROF extension. In this case close the other applications.

5. Ensure that you have the latest drivers and system updates and patches installed

Up-to-date system and drivers not only makes your computer more secure, but also may solve problems with Java Heap Dump file. Outdated drivers or software may have caused the inability to use a peripheral device needed to handle HPROF files.
