Extract text from Linux virtual hard disks (DISK)
To convert DISK virtual disks to another format, you need QEMU or other Disk Image software.
To convert other file formats to the "Virtual Hard Disk" file type, you need software like QEMU or a similar tool.
A .disk file is a virtual hard disk or raw loopback image typically used in Linux environments. These files act as block devices. They store complete, isolated filesystems (like ext4, xfs, or btrfs) inside a single container file. System administrators use them for virtualization, system backups, or isolated testing environments. You can mount them natively in Linux using the mount -o loop command or open them using virtualization software like QEMU or VirtualBox.
The main disadvantage of the .disk format is its opacity outside of Linux. Native Windows and macOS do not understand Linux filesystems. If you transfer a .disk file to a Windows machine, you cannot open it without specialized third-party drivers or virtual machine software. Furthermore, these files frequently exceed several gigabytes, making them difficult to share, upload, or quickly inspect.
To improve compatibility, users often convert .disk containers to standard virtualization formats like VMDK (for VMware), VDI, or VHD. If the goal is raw storage, converting to an IMG or ISO file is common. Be aware that converting a virtual disk alters its headers and metadata, which might break boot records if the disk contains an operating system.
This file format is exceptionally difficult to convert online. A .disk file is not just a document; it is a full filesystem container. Standard online converters fail instantly because they lack OS-level filesystem drivers and impose strict 100MB file size limits. Our analysis tools can inspect the file header to identify the partition table and detect the embedded filesystem type, allowing you to view internal metadata even if a full cloud conversion is impossible.
Convert.Guru analyzes your DISK file, detects the exact format, and lets you read the text inside.
Users also converted IMG, DSK, DMG, DPF, CIA, CHART, GPT, VHD, VMDK, VHDX, LVM, QCOW2 and VDI files.
If you want to convert DISK file to GPT, VHD, VMDK, VHDX, LVM, QCOW2, VDI, ISO, IMG, DMG, HDD or QCOW, you can use QEMU or similar software from the "Virtual Hard Disk Storage" 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 DISK, try QEMU or another comparable tool in the "Virtual Hard Disk 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 DISK converter.
