foldermix Docs
foldermix packs a directory into a single LLM-friendly context file. The v1 docs site is intentionally one page: enough to install the tool, run it immediately, and find the core commands without reading the full README end to end.
What It Does
Use foldermix when you want to turn a folder of text and document files into one context artifact for an LLM workflow.
Core capabilities:
- pack a folder into md, xml, or jsonl
- preview what will be included or skipped before packing
- handle optional PDF and Office converters when installed
- emit a machine-readable report for audits and cleanup workflows
Install
Core install
pip install foldermix
Homebrew
brew tap foldermix/foldermix
brew install foldermix
Homebrew installs the core feature set only.
Full optional converter support
# uv (recommended)
uv tool install "foldermix[all,markitdown]"
# pipx
pipx install "foldermix[all,markitdown]"
Optional extras:
- pdf: native PDF text extraction
- ocr: OCR fallback for textless PDFs
- office: docx / xlsx / pptx
- markitdown: additional converter support
Super Quick Start
Run this from the folder you want to pack:
foldermix pack . --out context.md
This writes one Markdown bundle to ./context.md.
Defaults worth knowing:
- default output format is Markdown (md)
- if you omit --out, foldermix writes a timestamped Markdown file such as foldermix_20260307_120000.md
Core Commands
pack
foldermix pack PATH [--out FILE] [--format md|xml|jsonl]
Use pack to create the final bundle.
Common flags:
- --report report.json: write a machine-readable report
- --dedupe-content: skip later exact-duplicate files by content hash
- --include-ext, --exclude-ext, --exclude-dirs, --exclude-glob
- --pdf-ocr: enable OCR fallback when OCR dependencies are installed
list
foldermix list PATH
Shows which files would be included by the current pack-style filtering rules.
skiplist
foldermix skiplist PATH
Shows which files would be skipped and why.
stats
foldermix stats PATH
Shows extension and byte-size statistics for the selected tree.
version
foldermix version
Prints the installed version.
Common Workflows
Config-first project workflow
foldermix init --profile engineering-docs
foldermix pack . --config foldermix.toml --format md --out context.md --report report.json
Research corpus batch run
find ./corpus -type f -print0 | foldermix pack ./corpus --config foldermix.toml --stdin --null --format jsonl --out research-context.jsonl --report research-report.json
Course refresh bundle
foldermix init --profile course-refresh --out foldermix.toml --force
foldermix pack ./previous-course --config foldermix.toml --format md --out course-refresh-context.md --report course-refresh-report.json
Duplicate cleanup before LLM ingestion
foldermix pack ./corpus --format md --out deduped-context.md --report dedupe-report.json --dedupe-content
Optional Dependency Guidance
Choose the install method based on the workflow:
- Homebrew: fastest system install, core features only
- uv tool: best isolated global install with extras
- pipx: similar isolated global install if you already use pipx
- virtualenv + pip: project-specific environments
If you already installed via Homebrew and later need extras, uninstall the Homebrew package and reinstall via uv tool, pipx, or a virtualenv.
