JDiskReport's tables don't migrate anywhere — note the top-50 paths and oldest trees, then verify and clean them in NullDisk.
Step by step
Run a fresh NullDisk scan
Open NullDisk, pick the same volume or folder, and let it measure everything — allocated size, hard links included. What you see now is ground truth.
Rebuild your cleanup queue
Drag each flagged item into the Ready-to-Remove collector. Review sizes, previews, and paths at leisure — nothing is deleted yet.
Trash once, verify twice
Move the collector to the Trash in one step, then rescan to confirm the reclaimed space. Uninstall the old tool only after the numbers check out.
Frequently asked questions
Can I export reports from JDiskReport?
JDiskReport's tables don't migrate anywhere — note the top-50 paths and oldest trees, then verify and clean them in NullDisk.
Will I lose anything by switching?
No — scans are reproducible. A fresh NullDisk scan of the same volume shows the same files with allocated-size accuracy, usually within minutes.
Is NullDisk hard to learn after JDiskReport?
Most switchers are productive in minutes: the radial map reads instantly, and the collector mirrors the 'gather then delete' habit you already have.
