Extract text from Persistent memory devices (VHDPMEM)
To convert VHDPMEM Memory devices to another format, you need Microsoft Hyper-V or other Disk Image software.
To convert other file formats to the "Hyper-V Storage File" file type, you need software like Microsoft Hyper-V or a similar tool.
A .VHDPMEM file is a Hyper-V Virtual Machine Persistent Memory Device file. It acts as the backing storage on a host system for virtual NVDIMM (Non-Volatile Dual In-line Memory Module) devices assigned to a virtual machine, allowing direct-mapped access to non-volatile memory.
These files are exclusively created and managed by Microsoft Hyper-V running on Windows Server or modern Windows Pro/Enterprise environments.
This format is highly specialized and restrictive. It requires a specific Windows host architecture with Hyper-V enabled and is entirely unsupported by alternative hypervisors like VMware or VirtualBox. Users often need to extract data or migrate the virtual machine, but the .VHDPMEM file itself is effectively a raw memory dump. It is useless without the matching virtual machine configuration and the specific host hardware context. Furthermore, these files pre-allocate space, consuming massive amounts of storage even if the virtual memory is empty.
The best workaround is moving the data into a standard VHDX or VHD virtual disk for broader compatibility, though this requires booting the original virtual machine to copy the contents.
Because this is a closed, proprietary system file, standard online converters fail to process it. It lacks a standard file system structure and instead represents byte-addressable persistent memory. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your VHDPMEM file, detects the exact format, and lets you read the text inside.
If you want to convert VHDPMEM file to ISO, IMG, DMG, VHD, VMDK, VDI, HDD, QCOW, QCOW2, RAW, VBOX or OVA, you can use Microsoft Hyper-V or similar software from the "Virtual Machine Persistent Memory" category. In the File menu, look for Save As… or Export….
To convert VFD, DMG, OVA, IMA, VBOX, ADF, PVS, VHD, OVF, ISO, DSK or IMG files to VHDPMEM, try Microsoft Hyper-V or another comparable tool in the "Virtual Machine Persistent Memory" category.
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 VHDPMEM converter.
