The short version

  • Each has a real cost: GParted partition operations risk data loss, and a backup before use is not optional advice; TreeSize it traverses directories rather than reading the NTFS master file table, so a local drive scan takes noticeably longer than the fastest alternatives.
  • They diverge on capability: GParted covers Graphical partitioning, TreeSize covers Free edition licensed for business.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GParted

  • Partition operations risk data loss, and a backup before use is not optional advice
  • Cannot safely modify mounted partitions, so system drives require booting the live image
  • Large move and resize operations can take hours and must not be interrupted
  • The interface is functional rather than reassuring, which matters for an operation this consequential

TreeSize

  • It traverses directories rather than reading the NTFS master file table, so a local drive scan takes noticeably longer than the fastest alternatives.
  • It is Windows only, so file servers running Linux or a NAS appliance need a different tool or a share mounted from a Windows machine.
  • Useful features are spread across three paid tiers, so the single capability a buyer needs frequently sits two tiers above the one they were considering.
  • Scanning large network shares generates significant traffic and takes hours, which means it has to be scheduled rather than run when someone asks the question.
  • Pricing is per licence with separate maintenance, so an accurate total for a team requires a quote rather than a figure from the website.

Answered from the vendors’ own pages

GParted: Is GParted free?

Yes, open source under the GPL.

TreeSize: Is TreeSize Free really free for business use?

Yes. JAM Software licenses the free edition for private and commercial use, which is the main reason it appears on corporate machines where other free analysers are not permitted.

GParted: Can GParted resize my system drive?

Not while it is mounted. Boot the GParted live USB image, which runs independently of the installed system.

TreeSize: Why is it slower than WizTree?

Method. WizTree reads the NTFS master file table; TreeSize walks the directory tree, which is slower but works on network shares and non-NTFS volumes.

GParted: Is it safe?

The operations are consequential and interruption during a move or resize can lose data. Back up before using it, every time.

TreeSize: Can it scan a NAS or Linux file server?

It scans them as network shares over SMB, with the speed penalty that implies. There is no agent that runs on the server itself.

TreeSize: What does the Enterprise tier add?

Scheduled unattended scans, stored historical results and reporting across servers, which is the difference between a cleanup tool and a storage reporting system.
