contiguity rule
About this tag
The contiguity rule is a constraint in Windows Disk Management and DiskPart that requires unallocated space to be immediately to the right of a partition for it to be extended. When unallocated space is not adjacent, these built-in tools refuse to expand the C: drive. Practical workarounds include relocating the unallocated space next to C: by moving or resizing the intervening partition, using a third-party partition manager that can handle non-contiguous moves, or carefully removing an intervening recovery partition with proper backups. This rule commonly affects users trying to reclaim space on Windows 10 or 11 when unallocated space exists elsewhere on the same disk.
