Your Disk Is Full… But Where?

Windows Explorer only shows file sizes. It doesn’t tell you which folders are quietly consuming tens of gigabytes. That’s where most people get stuck.

📂

Hidden space hogs

Old project folders, forgotten downloads, node_modules, cache directories, and Windows component stores can each eat 5–50 GB without you noticing.

⏱️

Manual hunting is slow

Opening Properties on every folder one by one is tedious and inaccurate. You waste hours and still miss the real culprits.

🧹

Cleanup tools miss context

Generic cleaners delete temp files but never show you the big picture of your own data. You need visibility, not blind deletion.

The Real App, Not a Mockup

Native Windows UI. Pick a folder, hit Scan, and get sortable sizes, file counts, and full paths — then export if you need a record.

Human + exact sizes See 31.49 GB and the exact byte count side by side so nothing is rounded away.
Cancel + export Stop a long scan cleanly. Save CSV or TXT for tickets, IT, or your own cleanup log.

Everything You Need to Reclaim Space

A focused tool built for one job: show you exactly which folders are taking space — fast, clearly, and privately.

🔍

Recursive deep scan

Scans every subfolder and file. You get accurate total sizes that include all nested content — no more guessing.

📊

Sortable list view

Click any column header to sort by size, name, file count, or path. Largest folders rise to the top instantly.

🌳

Tree view hierarchy

See the folder structure with sizes at every level. Expand and collapse branches to explore exactly where space is used.

⏹️

Cancel anytime

Started a full-drive scan by mistake? Hit Cancel. The app stays responsive and stops cleanly between directories.

📏

Human-readable sizes

Sizes are shown in KB, MB, GB, or TB automatically — plus the exact byte count when you need precision.

📁

File & folder counts

See how many files and subfolders each directory contains. Spot folders with millions of tiny files that slow everything down.

💻

Native, not Electron

Compiled with Lazarus / Free Pascal. Instant startup, tiny footprint, no browser engine, no extra runtimes to install.

🧾

Source included

The download includes the full project. Inspect it, learn from it, or rebuild it yourself — rare at this price.

Why People Buy Warkel’s Analyzer

Honest reasons it is worth $10 when your disk is full and you need answers now.

⚡ Built for speed

Native compiled code. No Electron bloat, no browser engine, no waiting for a web UI to load. It starts instantly and scans efficiently.

🔒 Your data stays yours

Zero telemetry. Zero online accounts. Zero cloud. The app never phones home. Perfect for work machines and privacy-conscious users.

🎯 Does one thing well

No cluttered interface full of “premium” upsells. No forced cloud accounts. Pick a folder, scan, and see results ranked by size.

💵 Pays for itself immediately

One forgotten node_modules, old VM, Steam library, or photo dump is usually worth more than $10 in disk space — and in time you don’t spend clicking Properties.

🛠️ Made for real cleanup

Identify node_modules, old virtual machines, duplicate project copies, game libraries, and Windows component stores that most cleaners ignore.

🛡️ Safe by design

It never deletes files for you. You review the report and clean up in Explorer. Full control, no accidental wipes.

📋 Report-ready output

Export CSV or plain text you can attach to a ticket, send to a manager, or archive after a major cleanup.

📦 Own it forever

$10 once. No subscription, no ads, no “Pro” gate. You get the complete app and the source after purchase.

💻 Light on old hardware

Small executable, modest RAM use. Comfortable on older laptops where heavy “cleaner suites” crawl.

What you get for $10

One payment. The whole product. Nothing held back behind a second checkout.

  • Windows 10 & 11 desktop app
  • List view and tree view
  • Recursive size, file, and folder counts
  • Hidden / system folder option
  • Cancelable scans
  • CSV and TXT export
  • Full Lazarus / Free Pascal source
  • Offline use — no account required

How It Works

Four simple steps from “disk full” to “I know exactly what to delete.”

1

Choose a folder

Browse to any drive or folder — C:\, your user profile, a project directory, or an external disk.

2

Hit Scan

The analyzer walks every subfolder, calculates sizes, and builds both a sortable list and a tree.

3

Spot the giants

Results appear sorted by size (largest first). Instantly see which folders are costing you the most space.

4

Clean with confidence

Open the worst offenders in Explorer and delete or archive what you no longer need. Export a report if you want a record.

What Users Say

Real problems, real results.

I found a 28 GB node_modules folder from an old project I forgot existed. Deleted it in 30 seconds. This tool paid for itself in the first minute — and it only cost $10.

Marcus T.
Full-stack developer

Finally something that just works without asking me to create an account or watch a 30-second ad. Scanned my whole D: drive and showed me exactly where my photos and videos were piling up.

Elena R.
Photographer

We use it on support tickets when users say “my disk is full.” Export the CSV, attach it to the ticket, and everyone can see the same numbers. Simple and professional.

Frequently Asked Questions

Quick answers to common questions.

How much does it cost?
A simple one-time payment of $10. No subscriptions, no recurring fees, no “premium” upsells later. You pay once and own it.
Are there any hidden fees or subscriptions?
No. $10 is the full price. No monthly plans, no in-app purchases, and no forced upgrades. You get the complete application.
Does it send any data online?
No. The program runs completely offline. It never contacts any server. Your folder structure and file sizes stay on your machine.
Will it delete files for me?
No. It only analyzes and reports. You decide what to delete using Windows Explorer or your preferred tool. This keeps you in full control and avoids accidental data loss.
How long does a scan take?
Small folders finish in under a second. A typical user profile or Program Files folder usually takes a few seconds to a minute. A full multi-terabyte drive can take longer — you can cancel at any time.
Can I scan network drives or external disks?
Yes. Any folder path Windows can see — local drives, external USB disks, and mapped network drives — can be scanned.
What are the system requirements?
Windows 10 or 11 (64-bit recommended). Very light on RAM and CPU. Built with Lazarus so it runs as a native executable with no extra runtimes required beyond a normal Windows installation.
Is the source code available?
Yes. The download includes the full Lazarus / Free Pascal project so you can inspect, modify, or rebuild it yourself.
