FileDisk

FileDisk is a lightweight Windows utility developed by bosse that creates virtual disk drives by mounting ordinary files as if they were physical hard disks. Currently at version 22, the driver intercepts low-level disk I/O requests and redirects them to the chosen file or set of files, letting the operating system treat the image as a fully functional local drive with its own drive letter and file system. Because the mounted volume behaves exactly like a real partition, any Windows program—including backup tools, forensic suites, encryption containers, or legacy installers—can read and write data without modification, making the software useful for scenarios such as mounting raw disk images for offline analysis, creating temporary scratch disks that disappear on reboot, or distributing pre-configured development environments as single portable files. Administrators also employ FileDisk to test boot sectors, verify disk-image backups, or provide isolated storage areas that bypass physical hardware limitations. The driver supports common file systems including NTFS, FAT32, and exFAT, and it can operate in read-only mode to protect original images from accidental writes. Installation is straightforward, adding a small kernel-mode component that integrates with Windows’ existing storage stack, and the tool exposes a simple command-line interface for mounting, unmounting, and listing active virtual disks. FileDisk is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
