Extract text from Hyper-V checkpoints (AVHDX)
To convert AVHDX checkpoints to another format, you need Microsoft Hyper-V or other Disk Image software.
To convert other file formats to the "Differencing Virtual Disk" file type, you need software like Microsoft Hyper-V or a similar tool.
The .avhdx file format is a differencing virtual hard disk used by Microsoft Hyper-V to store virtual machine checkpoints (snapshots). When a user creates a snapshot of a VM, the system freezes the original VHDX file and creates an .avhdx file to capture all subsequent writes and system changes. This allows administrators to roll back the system to the exact state it was in when the checkpoint was taken.
While highly useful for backups and testing, the .avhdx format is fraught with practical disadvantages. These files are intrinsically tied to their parent disk; without the original VHDX and the precise snapshot chain, the .avhdx data is entirely fragmented and unusable. Furthermore, because they record all new data writes, .avhdx files can grow indefinitely, often consuming massive amounts of physical storage and degrading VM performance over time. Users typically need to convert or merge them back into a single standard virtual disk format to recover space or migrate VMs to other hypervisors.
Converting an .avhdx usually means merging it back into a standard VHDX file, or converting the entire compiled disk chain to VMDK (for VMware) or a RAW image. Because this is a complex, block-level differencing format, standard online converters fail to process it as they lack the parent disk context.
Convert.Guru analyzes your AVHDX file, detects the exact format, and lets you read the text inside.
Users also converted CONF, SPDESIGNCONFIG, MAP, VHDX, VHD, QCOW2, VMDK and VDI files.
If you want to convert AVHDX file to VHDX, VHD, QCOW2, VMDK, VDI, SYS, DLL, EXE, DRV, VXD, 386 or COM, you can use Microsoft Hyper-V or similar software from the "Virtual Machine Checkpoint Storage" category. In the File menu, look for Save As… or Export….
To convert MSI, EXE, REG, MST, LNK, CAB, CAT, DRV, INF, SYS, MSU or DLL files to AVHDX, try Microsoft Hyper-V or another comparable tool in the "Virtual Machine Checkpoint Storage" 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 AVHDX converter.
