Toggle on Storage Sense, then click <em>Temporary files<\/em> and remove items like <em>Downloads<\/em> (only if you don\u2019t need them), <em>Delivery Optimization Files<\/em>, and <em>Windows Update Cleanup<\/em>. Click <em>Clean now<\/em>.<\/li>\n<li><strong>Disk Cleanup<\/strong>: Press Start, type \u201cDisk Cleanup\u201d, right-click and <em>Run as administrator<\/em>. Choose your system drive (usually C:). Click <em>Clean up system files<\/em>, then tick <em>Windows Update Cleanup<\/em>, <em>Temporary files<\/em>, <em>Device driver packages<\/em>, <em>Delivery Optimization Files<\/em>, etc. Review and confirm.<\/li>\n<\/ul>\n<h3>2) Clear user temp files and browser caches<\/h3>\n<ul>\n<li>Open the Run dialog (Windows+R), type <strong>%temp%<\/strong>, press Enter. Select all and delete. Skip any files in use.<\/li>\n<li>In the Run dialog, type <strong>temp<\/strong>, press Enter.

Note: This disables Fast Startup on some systems.<\/li>\n<li><strong>System Restore size<\/strong>: Control Panel &gt; System &gt; System Protection &gt; Configure.

You can remove <em>app-specific<\/em> folders you recognize. Avoid touching \u201c\/Library\u201d and \u201c\/System\u201d.<\/li>\n<li>For browsers, use their in-app <em>Clear History \/ Clear Cache<\/em> options (Safari: Settings &gt; Advanced &gt; Show Develop menu, then Develop &gt; Empty Caches; Chrome\/Firefox similar to Windows steps).<\/li>\n<\/ul>\n<h3>4) Review big items<\/h3>\n<ul>\n<li><strong>iOS backups<\/strong>: Finder &gt; Your iPhone &gt; Manage Backups\u2026 Delete old device backups.<\/li>\n<li><strong>Mail downloads\/attachments<\/strong>: Mail &gt; Preferences &gt; Accounts &gt; download settings; remove large attachments you no longer need.<\/li>\n<li><strong>iCloud Drive<\/strong>: Enable \u201cOptimize Mac Storage\u201d to keep full-resolution items in the cloud when space is low.<\/li>\n<\/ul>\n<h2 id=\"hunt-space-hogs\">Hunt Down Space Hogs on Both Platforms<\/h2>\n<h3>Use built-in search filters<\/h3>\n<ul>\n<li><strong>Windows<\/strong>: In File Explorer, search your drive for \u201csize:&gt;1GB\u201d then sort by size.

Avoid deleting system folders themselves.<\/p>\n<p><strong>Will removing Time Machine local snapshots delete my backups?<\/strong><\/p>\n<p>No. Deleting local snapshots only frees internal disk space.
