The short version

  • Only TreeSize has a free tier, so it costs nothing to try first.
  • Each has a real cost: TreeSize it traverses directories rather than reading the NTFS master file table, so a local drive scan takes noticeably longer than the fastest alternatives.; VTScada licences are per installed PC rather than per system, so a redundant pair plus a development machine means paying three times unless you buy the discounted multi-server bundles.
  • They diverge on capability: TreeSize covers Free edition licensed for business, VTScada covers Automatic version control.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

VTScada

  • Licences are per installed PC rather than per system, so a redundant pair plus a development machine means paying three times unless you buy the discounted multi-server bundles.
  • Thin client licensing is by concurrent connection and is priced steeply at scale: unlimited thin clients on a 50,000 tag system costs 59,395 USD on top of the base licence, more than the base licence itself.
  • It is Windows only with no Linux or container deployment, which rules it out of modern edge and virtualised architectures that other SCADA products now support.
  • SupportPlus at 15 percent of the original software price must be maintained continuously; if you let it lapse you cannot simply resume, and reinstatement is negotiated rather than published.
  • The scripting environment and the integrator pool are both proprietary and small, so finding a second-source integrator in a region where Trihedral has thin coverage is genuinely difficult.

Answered from the vendors’ own pages

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.

VTScada: Is VTScada perpetual or subscription?

Perpetual. Licences are one-time purchases per installed PC, with an optional annual SupportPlus contract at 15 percent of the original software price.

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.

VTScada: Are drivers extra?

No. Standard and proprietary I/O drivers, the historian, trending, reporting and security are all included in the base licence.

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.

VTScada: What does support actually cost?

Annual SupportPlus is 15 percent of total software purchase price. Adding 24/7 emergency support is a further 5 percent with a 1,540 USD minimum.

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.

VTScada: Does it run on Linux?

No. VTScada is Windows only.
