filoma 1.7.5

Modular Python tool for profiling files, analyzing directory structures, and inspecting image data

Fast, multi-backend file/directory profiling and data preparation for machine learning workflows.

Installation • Quickstart • Cookbook • Source Code

---

filoma helps you analyze file directory trees, inspect file metadata, and prepare your data for exploration and modelling. It can achieve this blazingly fast using the best available backend (Rust, fd, or pure Python) ⚡🍃

---

Key Features

• 🚀 High-Performance Backends: Automatic selection of Rust, fd, or Python for the best performance.
• 📊 Rich Directory Analysis: Get detailed statistics on file counts, extensions, sizes, and more.
• 🔍 Smart File Search: Use regex and glob patterns to find files with FdFinder.
• 📈 DataFrame Integration: Convert scan results to Polars DataFrames for powerful analysis.
• 🖼️ Image Profiling: Extract metadata and statistics from various image formats.
• 🔀 ML-Ready Splits: Create deterministic train/validation/test datasets with ease.

Installation

Install filoma using uv or pip:

uv pip install filoma

Workflow Demo

This guide follows a typical filoma workflow, from basic file profiling to creating machine learning datasets.

1. Profile a Single File

Start by inspecting a single file. filoma provides a detailed dataclass with metadata.

from filoma import probe_file

# Profile a file
file_info = probe_file("README.md")

print(f"Path: {file_info.path}")
print(f"Size: {file_info.size_str}")
print(f"Modified: {file_info.modified}")

For images, probe_image gives you additional details like shape and pixel statistics.

from filoma import probe_image

# Profile an image
img_info = probe_image("images/logo.png")
print(f"Type: {img_info.file_type}")
print(f"Shape: {img_info.shape}")

2. Analyze a Directory

Scan an entire directory to get a high-level overview.

from filoma import probe

# Analyze the current directory
analysis = probe('.')

# Print a summary report
analysis.print_summary()

Directory Analysis: /project (🦀 Rust (Parallel)) - 0.27s
Total Files: 17,330    Total Folders: 2,427    Analysis Time: 0.27 s

3. Convert to a DataFrame

For detailed analysis, convert the scan results into a Polars DataFrame.

from filoma import probe_to_df

# Scan a directory and get a DataFrame
df = probe_to_df('.')

print(df.head())

4. Enrich Your Data

Add more context to your DataFrame, like file depth and path components, with the enrich() method.

# The DataFrame returned by probe_to_df is a filoma.DataFrame
# with extra capabilities.
df_enriched = df.enrich()

print(df_enriched.head())

5. Create ML-Ready Splits

filoma makes it easy to split your files into training, validation, and test sets for machine learning. You can even group files by parts of their path to prevent data leakage.

from filoma import ml

# Split the data, grouping by parent directory
train, val, test = ml.split_data(df, how='parts', parts=(-2,), seed=42)

print(f"Train: {len(train)}, Validation: {len(val)}, Test: {len(test)}")
