.PHD File Extension

Photo project created by PhotoDirector, a program used for editing digital photos; supports imported photos from many different camera RAW formats, including .DNG, .CR2, .SRF, and many others; contains the library of imported images and stores any user edits; used as the native project save format and is saved with other data files and folders that contain the digital photo data.

Data file created in the Portable Heap Dump format, which is used to create Java heap dump files using IBM's version of the Java Virtual Machine (JVM); may contains a record of all Java heap objects; used for debugging application errors such as memory leaks.

Portable heap dumps can be generated by setting the following environment variable parameters: IBM_HEAP_DUMP=true and IBM_HEAPDUMP=true. PHD files may be saved in a text or a binary format. However, the binary format is much smaller in file size. To specify the text format, set the IBM_JAVA_HEAPDUMP_TEXT=true environment variable.

NOTE: Portable heap dumps are typically generated by killing a running Java application. Therefore, to create a PHD file, start your Java program with the required environment variables set and then kill it.
