01
Live expandable tree
Files and folders appear in an expandable hierarchy as the scan runs, with Path, Type and Size visible in the main window.
Windows desktop / FileTreeLister
Fast folder listings. Clean exports.
Turn any folder or drive into a readable, shareable file tree. Watch the hierarchy appear live, inspect file and folder types and sizes, then export the finished inventory to CSV, TXT or PDF.

Features
Everything needed to make a folder legible.
Useful for release notes, handovers, audits, backups and those drives labelled “misc” that have been quietly judging you since 2014.
02
Folder totals
See calculated folder sizes directly in the tree with automatic KB, MB and GB formatting — useful even on something as large as C:\Windows.
03
Structured exports
CSV output includes hierarchy depth, names, relative and full paths, item type, directory flags and size data for proper spreadsheet analysis.
04
Cancel safely
Stop a long scan without freezing the application or wrestling Windows Task Manager.
05
Remembered settings
The last selected folder and export preferences are retained between sessions.
06
Open source
Source code is published on GitHub under the MIT licence.
How it works
Choose. Scan. Export.
Select a folder or drive, click Go and watch the hierarchy populate. The example below scans C:\Windows and completes with 277,231 items before exporting the same structure to CSV.
Choose a folder
Browse to a normal folder, archive, external drive or full drive root.
Run the scan
The tree fills in live while file counts and folder sizes are calculated.
Export the result
Create a CSV, TXT or PDF copy for sharing, checking or record-keeping.
FileTreeLister in action
A real Windows scan and the resulting CSV.
These are genuine FileTreeLister outputs shown at their original 3:2 proportions: first the live application scanning C:\Windows, followed by the exported CSV opened in Excel.
Good for
Release notes, audits, archives and handovers.
- Documenting software or project releases.
- Checking backup and archive contents.
- Creating file inventories for audits or handovers.
- Reviewing old drives before deletion or migration.
Windows notes
Lightweight and straightforward.
The downloadable Windows build does not require Python on the target computer. Windows SmartScreen may warn about an unsigned executable, which is common for small independent software releases.
Open source and free to use.
