ncdu, alternative Linux à Active System Optimizer
Mis à jour le
Notre avis
ncdu is a solid replacement for the disk‑usage part of Active System Optimizer, especially for users who are comfortable in a terminal. It shows directory sizes, lets you delete files directly, and runs on any Linux distro. It does not touch registry‑like settings because Linux has no registry, so it covers the cleanup and speed‑up claims of Active System Optimizer for the majority of users who mainly want to free space and inspect disk usage.

Ce qui fonctionne pareil
- Both provide a quick way to see what is taking up disk space
- Both allow the user to delete unnecessary files
- Both are free to use (ncdu is open source, Active System Optimizer is free but not open source)
- Both aim to improve system performance by removing clutter
Ce qui change
- Active System Optimizer claims to repair registry errors, which ncdu does not address
- Active System Optimizer offers a graphical, one‑click interface; ncdu is command‑line and keyboard‑driven
- Active System Optimizer can claim to speed up the system beyond disk cleanup; ncdu only shows usage and allows deletion
- Active System Optimizer is Windows‑only; ncdu runs on Linux, macOS, and BSD
- Active System Optimizer may have extra cleaning modules (temporary files, caches) that ncdu does not automatically target
Ouvrir vos fichiers Active System Optimizer
Active System Optimizer produces no standard file format that ncdu can read. You cannot import its data into ncdu. If you need to migrate settings, you would have to manually delete temporary files or adjust configuration files yourself.

Installer ncdu sous Linux
sudo apt install ncdusudo apt install ncdusudo dnf install ncdusudo pacman -S ncdusudo zypper install ncduQuestions fréquentes
Can ncdu delete files I don’t want to delete?
ncdu only deletes what you explicitly choose. Use the arrow keys to select a file or directory and press 'd' to delete. Always review before confirming.
Does ncdu repair configuration files like Active System Optimizer claims?
No. ncdu only shows disk usage. If you need to fix broken configuration files, you must edit them manually or use another tool.
Is ncdu safe to use on a production server?
Yes, but exercise caution. Because it can delete files, double‑check selections and consider running a dry‑run or backing up important data first.
