The short version

  • Each has a real cost: Starbucks loading a prepaid balance onto the app effectively lends Starbucks money interest-free until it is spent, and Starbucks has reported billions of dollars in unredeemed stored value outstanding at any time.; WinDirStat it walks the directory tree rather than reading the NTFS master file table, so a full scan takes minutes where WizTree takes seconds on the same drive.
  • They diverge on capability: Starbucks covers Mobile order and pay, WinDirStat covers Treemap visualisation.
  • 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.

Starbucks

  • Loading a prepaid balance onto the app effectively lends Starbucks money interest-free until it is spent, and Starbucks has reported billions of dollars in unredeemed stored value outstanding at any time.
  • Mobile order pickup often creates its own bottleneck at busy stores, so the convenience of skipping the register queue can be offset by waiting at the pickup counter instead.
  • Rewards redemption values and item eligibility change periodically, so accumulated Stars do not have a fixed, predictable cash value over time.
  • The app collects detailed purchase history to power targeted offers, which is the trade for the free loyalty programme rather than a neutral convenience feature.
  • Auto-reload linked to a card can catch users off guard with unexpected small recurring charges if they are not tracking their balance.

WinDirStat

  • It walks the directory tree rather than reading the NTFS master file table, so a full scan takes minutes where WizTree takes seconds on the same drive.
  • The version most users have installed is the 2007 build, and because it was dormant for so long, search results and download mirrors still point at it.
  • It is Windows only, so a mixed estate needs a different tool for macOS and Linux machines.
  • There is no scheduling, reporting or export for fleet use, so it answers a question on one machine at a time rather than monitoring storage across an organisation.
  • Hard links, junctions and deduplicated volumes can be counted in ways that make the totals disagree with what Windows reports, which causes confusion on servers.

Answered from the vendors’ own pages

Starbucks: Does it cost anything to join Starbucks Rewards?

No, joining and using the app is free; you pay only for what you order.

WinDirStat: Is WinDirStat still maintained?

Yes. It was dormant from around 2007 until new maintainers resumed development and released the 2.x line with multithreaded scanning and current Windows support.

Starbucks: What happens to money loaded onto the app if I stop using Starbucks?

It remains as a stored balance unless redeemed; Starbucks does not pay interest on it and, subject to local law, unredeemed balances can eventually be treated as breakage revenue.

WinDirStat: Can I use it at work?

Yes. It is GPL licensed with no personal-use restriction, which is the practical advantage over free-for-personal-use alternatives in this category.

Starbucks: Can I pay without preloading a balance?

Yes, many stores accept direct card or contactless payment without using the app's stored value feature.

WinDirStat: Why is it slower than WizTree?

Different method. WizTree reads the NTFS master file table directly; WinDirStat traverses directories, which is slower but works on any filesystem, including network shares.

WinDirStat: Does it run on macOS or Linux?

No. Separate projects exist with similar treemap interfaces, but WinDirStat itself is Windows only.
