Hey everyone!

I spent a lot of time searching for hidden cache directories across Windows—from GPU shader folders and developer build caches to game launchers and browser temp files.

To save others the trouble, I combined all 40+ directory paths into a free open-source script called ZeroCleaner.

I built it specifically to be 100% safe. It only deletes temporary cache folders without touching your saved logins, cookies, or browser passwords.

What it cleans:

• GPU Shaders (NVIDIA, AMD, DirectX)
• Browsers (Chrome, Edge, Brave, Firefox, Opera)
• Dev Caches (npm, pip, Yarn, Go, Rust/Cargo, VS Code)
• Game Launchers (Steam, Epic Games, EA, Ubisoft)
• Apps (Discord, Telegram, Slack, Notion, Spotify)

It also includes a dry-run mode (-WhatIf) so you can preview how much space you can free up before deleting anything.

You can check out the source code on GitHub: https://github.com/ZeroIQs/ZeroCleaner

(just run the .bat file and you are good to go)

Let me know if there are any other hidden cache directories I should add!

Disclaimer: Always check and inspect code before downloading or running scripts on your machine!

Hey everyone,

Whenever I needed to split a PDF, merge documents, or compress a file, I’d have to use sites like ILovePDF. The problem? You have to upload your bank statements, tax forms, or contracts to a random server in the cloud, which feels like a massive privacy risk.

So, I spent some time building ExPDF (https://expdf.space). as a side project.

I engineered it so that everything runs locally on your device via HTML5 and JavaScript. Your files never touch a server, meaning it's mathematically impossible for your data to be stolen or tracked.

Features I built in:

• Visual Extract/Remove: Drag and drop your pages to extract what you want, or delete what you don't.
• Batch JPEG Export: Select 50 pages and instantly download them as a ZIP file of high-res JPEGs.
• Deep Compression: A built-in flattening engine to crush PDF file sizes without destroying text quality.
• Completely Free & No Limits: No "You have reached your daily limit of 2 documents."

It works perfectly on PC and Mobile (Tap-to-swap pages). I'd love for you guys to try it out and let me know if it's helpful or if there are any features I should add next!
