阅读14分钟电脑缓存怎么清理？按 Win+R 输入 %temp% 删除临时文件、用「磁盘清理」勾选系统缓存、进浏览器设置清除 Cookie 与缓存图片，是多数情况下最快见效的方式。
缓存堆积通常是系统运行、更新或浏览器长期使用的正常产物，清理后立刻可释放空间、改善卡顿，以下 5 个方法在 Windows 10/11 实测可用，按从易到难逐个排查，修好即停。
适用系统：Windows 10/11；最后更新：2026-06-22。
电脑缓存是什么情况
缓存是系统与应用程序为加速下次访问而暂存的临时数据，常见路径包括 C:\Windows\Temp、C:\Users\用户名\AppData\Local\Temp、C:\Windows\SoftwareDistribution\Download（Windows 更新缓存）和浏览器的 Cache 文件夹。长期不清理会导致 C 盘占用率飙升，严重时出现"磁盘空间不足，无法完成操作"提示，程序启动缓慢甚至崩溃。

先定位缓存来源、再对症清理，能省去大量盲目扫描的时间。
方法一 用「磁盘清理」一次清系统缓存
Windows 内置「磁盘清理」可在一次扫描中集中处理临时文件、缩略图缓存、Windows 错误报告（C:\ProgramData\Microsoft\Windows\WER）和旧系统更新文件，是清 C 盘缓存最安全的第一步。
操作步骤
- 按
Win+S搜索「磁盘清理」，打开应用。 - 选择 C: 盘，点「确定」，等待扫描。
- 点击「清理系统文件」，再次选 C: 盘，可额外释放 Windows Update 缓存（
C:\Windows\SoftwareDistribution\Download）。 - 勾选「临时文件」「缩略图」「Internet 临时文件」「Windows 错误报告和反馈诊断」等项。
- 点「确定」→「删除文件」，确认后开始清理。
磁盘清理扫描结束后，可在列表里看到每类缓存的具体大小，再决定勾选哪些，不会误删用户文档。

方法二 手动删除临时文件夹（%temp% 路径）
通过运行框直接进入临时文件夹手动删除，可清理磁盘清理工具扫不到的应用残留缓存，适合 C 盘空间告急时快速补充清理。
操作步骤
- 按
Win+R，输入%temp%，回车，进入C:\Users\用户名\AppData\Local\Temp。 - 按
Ctrl+A全选，按Delete删除；提示"某文件正在使用"时点「跳过」，不影响其余删除。 - 再次按
Win+R，输入temp，进入C:\Windows\Temp，同样全选删除。 - 右键桌面「回收站」→「清空回收站」，彻底释放磁盘空间。
被系统占用无法删除的文件重启后会自动解锁，下次再清一遍即可，不必强制删除。
方法三 用「存储感知」自动清缓存（Windows 10/11）
Windows 存储感知可在 C 盘空间低于阈值时自动删除临时文件和回收站内容，适合不想手动维护的用户设置一次长期生效。
操作步骤
- 按
Win+I打开「设置」，依次点「系统」→「存储」。 - 找到「存储感知」开关，打开；点「配置存储感知或立即运行」进入详细设置。
- 在「运行存储感知」下拉中选「每月」或「当磁盘空间不足时」。
- 勾选「删除临时文件」和「回收站 30 天以上文件」。
- 滚动到底部，点「立即清理」可手动触发一次，查看实际释放量。
开启存储感知后无需记住每次手动清理，系统会根据磁盘状态自动处理临时缓存文件。

方法四 清理浏览器缓存与 Cookie
系统缓存清理不会影响浏览器缓存，两者需分开处理；长期不清浏览器缓存会导致网页加载异常，或 Edge/Chrome 在 AppData\Local\Microsoft\Edge\User Data\Default\Cache 目录积累超 GB 级数据。
操作步骤（以 Chrome 为例）
- 点右上角「三点」菜单→「设置」→「隐私设置和安全性」→「清除浏览数据」。
- 勾选「缓存的图片和文件」和「Cookie 及其他网站数据」。
- 时间范围选「不限时间」，点「清除数据」。
- Edge 操作类似：设置→「隐私、搜索和服务」→「清除浏览数据」→「选择要清除的内容」。
- Firefox：菜单→「设置」→「隐私与安全」→「Cookie 和站点数据」→「清除数据」。
清理 Cookie 会退出已登录网站，操作前确认重要账号密码已记录或浏览器已保存。
方法五 关闭休眠释放 hiberfil.sys 缓存
休眠文件 C:\hiberfil.sys 默认大小等于物理内存容量（8 GB 内存 = 约 8 GB 文件），不使用休眠功能的用户可通过管理员命令关闭并删除，立即释放这部分 C 盘空间。
操作步骤
- 按
Win+S搜索「cmd」，右键「命令提示符」→「以管理员身份运行」。 - 输入命令
powercfg -h off，回车；系统会自动删除hiberfil.sys。 - 再次打开「磁盘清理」或用资源管理器确认 C 盘空间已释放。
- 若之后需要恢复休眠，以管理员运行
powercfg -h on即可。
关闭休眠后「开始菜单→电源」中「休眠」选项消失属正常现象，睡眠和关机功能不受影响。

常见问题
清理缓存会删掉我的文件或软件吗？
不会。磁盘清理和 %temp% 删除的都是临时文件，与「文档」「桌面」等个人文件完全隔离，已安装软件也不受影响。但清除浏览器 Cookie 会退出已登录网站，注意提前保存账号信息。
清理后 C 盘空间过几天又满了怎么办？
说明有程序在持续生成大量日志或下载缓存。建议打开「设置→存储→存储使用情况」，查看哪类数据增长最快，针对性清理；或开启存储感知自动定期清理，防止再次积满。
Win10 缓存文件夹在哪里？
主要位置：系统临时文件 C:\Windows\Temp 和 C:\Users\用户名\AppData\Local\Temp；Windows 更新缓存 C:\Windows\SoftwareDistribution\Download；Edge 缓存 C:\Users\用户名\AppData\Local\Microsoft\Edge\User Data\Default\Cache。可手动进入删除或用磁盘清理统一处理。
清缓存会让网页或软件变慢吗？
短期内首次访问同一网页或启动同一程序会略慢，因为缓存需要重新生成；之后恢复正常。整体来看，定期清缓存带来的空间释放与流畅度提升远大于这点短暂影响。
清理位置历史（定位缓存）在哪里操作？
进入「设置→隐私→位置信息」，滚动到「位置记录」，点「清除」即可删除本机保存的位置历史，不影响 GPS 或定位功能本身的开关状态。
