C盘垃圾文件分析器 v2.0

Drive C Junk File Analyzer v2.0

📌 功能概述

📌 Feature Overview

这是一个只读分析工具，用于深度扫描C盘上的可清理/可迁移文件，生成包含以下三大维度的详细报告：

🧠 智能删除建议 — 每个项目都给出明确的是否推荐删除的判断及理由
📦 迁移方案 — 标识哪些数据可以通过配置修改/符号链接等方式移出C盘到其他磁盘
🔬 深度扫描 — 超越v1.0的基础扫描，覆盖大文件TOP N、更多应用缓存、系统隐藏空间占用

本技能不会删除或修改任何文件，仅提供分析和可执行的操作方案。

This is a read-only analysis tool designed for deep scanning of cleanable/migratable files on Drive C, generating a detailed report covering three key dimensions:

🧠 Intelligent Deletion Suggestions — Clear recommendations on whether to delete each item, along with reasons
📦 Migration Solutions — Identify which data can be moved from Drive C to other disks via configuration changes/symbolic links, etc.
🔬 Deep Scanning — Beyond the basic scanning of v1.0, covering top N large files, more application caches, and system hidden space usage

This skill will not delete or modify any files, it only provides analysis and actionable operation plans.

🎯 适用场景

🎯 Applicable Scenarios

C盘空间不足，需要释放空间
想了解哪些文件占用了C盘空间
想把某些缓存/数据从C盘迁移到D盘或其他盘
定期系统维护和清理

Troubleshoot "mysteriously disappearing" space on Drive C (system hidden files)

⚙️ 工作流程

⚙️ Workflow

步骤1：获取C盘基础信息 + 隐藏空间检测

Step 1: Get Drive C Basic Information + Hidden Space Detection

powershell

undefined

powershell

undefined

C盘基础信息

Drive C basic information

$drive = Get-PSDrive C $totalGB = [math]::Round(($drive.Used + $drive.Free) / 1GB, 2) $usedGB = [math]::Round($drive.Used / 1GB, 2) $freeGB = [math]::Round($drive.Free / 1GB, 2)

休眠文件 (hiberfil.sys)

Hibernation file (hiberfil.sys)

$hiber = if (Test-Path "C:\hiberfil.sys") { (Get-Item "C:\hiberfil.sys").Length } else { 0 }

页面文件 (pagefile.sys)

Page file (pagefile.sys)

$page = if (Test-Path "C:\pagefile.sys") { (Get-Item "C:\pagefile.sys").Length } else { 0 }

系统还原点

System restore points

$restorePoints = Get-ComputerRestorePoint -ErrorAction SilentlyContinue $rpCount = @($restorePoints).Count

---

$restorePoints = Get-ComputerRestorePoint -ErrorAction SilentlyContinue $rpCount = @($restorePoints).Count

---

步骤2：分类深度扫描（每个项目含三维度信息）

Step 2: Classified Deep Scanning (Each item includes three-dimensional information)

每个扫描项的输出格式必须包含：

📍 位置

📏 大小

✅/⚠️/❌ 删除建议：推荐删除 / 谨慎删除 / 不建议删除（附理由）

🚚 可迁移性：可迁移(附方法) / 不可迁移 / 部分可迁移

Output format for each scan item must include:

📍 Location

📏 Size

✅/⚠️/❌ Deletion Suggestion: Recommended to delete / Delete with caution / Not recommended to delete (with reasons)

🚚 Migratability: Migratable (with method) / Not migratable / Partially migratable

🔴 类别A：系统隐藏大文件（高收益但需谨慎）

🔴 Category A: System Hidden Large Files (High benefit but need caution)

A1. 休眠文件 hiberfil.sys

A1. Hibernation file hiberfil.sys

powershell

$path = "C:\hiberfil.sys"
if (Test-Path $path) {
    $size = (Get-Item $path).Length
    Write-Host "🔴 休眠文件: $([math]::Round($size/1GB, 2)) GB"
}

属性	详情
位置	`C:\hiberfil.sys`
大小	通常 = 物理内存大小
删除建议: ⚠️ 谨慎删除	如果你不使用休眠功能(合盖睡眠)，可以安全关闭以释放等于内存大小的空间。如果使用休眠则不能删
可迁移: ❌ 不可迁移	只能开启/关闭

操作方案:

powershell

undefined

powershell

$path = "C:\hiberfil.sys"
if (Test-Path $path) {
    $size = (Get-Item $path).Length
    Write-Host "🔴 Hibernation file: $([math]::Round($size/1GB, 2)) GB"
}

Attribute	Details
Location	`C:\hiberfil.sys`
Size	Usually = Physical memory size
Deletion Suggestion: ⚠️ Delete with caution	If you don't use hibernation (lid-close sleep), you can safely disable it to free up space equal to your memory size. Do not delete if you use hibernation
Migratability: ❌ Not migratable	Can only be enabled/disabled

Operation Plan:

powershell

undefined

关闭休眠（释放空间，管理员PowerShell）

Disable hibernation (free up space, run as administrator in PowerShell)

if (Test-Path $path) {
    $size = (Get-Item $path).Length
    Write-Host "🔴 Page file: $([math]::Round($size/1GB, 2)) GB"
}

Attribute	Details
Location	`C:\pagefile.sys`
Size	Usually = Physical memory size × 1~1.5 times
Deletion Suggestion: ❌ Not recommended to delete directly	Page file is a core component of system virtual memory; deleting it may cause system instability or program crashes
Migratability: ✅ Migratable to other disks	Move the page file to Drive D via system settings

Operation Plan (Migrate to Drive D):

1. Win+R → sysdm.cpl → Advanced → Performance Settings → Advanced → Virtual Memory

示例回复

Sample Response

好的！我现在用 C盘分析器 v2.0 开始深度扫描你的C盘。

🔍 只读模式，不会修改任何文件

正在扫描：基础信息 → 隐藏空间 → 临时文件 → 开发工具缓存 → 大文件TOP N → 特殊占用...

[展示完整报告]

你想要：

清理某些项目？ （告诉我编号，我帮你执行，每个都会先确认）

迁移开发工具缓存到D盘？ （npm/node-gyp/pip/cargo等，我帮你改配置）

生成完整报告文档？ （保存到桌面供你慢慢看）

本Skill旨在帮助你深度理解C盘空间去向，并提供删除和迁移两种释放空间的方案。 v2.0 — 2026-04-02

Okay! I'm starting a deep scan of your Drive C using Drive C Analyzer v2.0.

🔍 Read-only mode, no files will be modified

Scanning in progress: Basic information → Hidden space → Temporary files → Development tool caches → Top N large files → Special space occupants...

[Display complete report]

Would you like to:

Clean up certain items? (Tell me the numbers, I will execute them and confirm each one first)

Migrate development tool caches to Drive D? (npm/node-gyp/pip/cargo, etc., I can help you modify configurations)

Generate a complete report document? (Save to desktop for you to review later)

This Skill aims to help you deeply understand where Drive C space is being used, and provides two solutions to free up space: deletion and migration. v2.0 — 2026-04-02
