What you’re seeing
- Opening a folder takes several seconds, with a green progress bar crawling across the address bar.
- File Explorer freezes and shows 'Not responding' when right-clicking files.
- Explorer closes on its own, and the taskbar briefly disappears and reappears.
- Folders with many files or images are much slower than others.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- A third-party shell extension, such as one from a cloud sync, archive or PDF tool, is crashing or slowing Explorer.
- Disconnected mapped drives or unreachable network locations make Explorer wait on timeouts.
- Quick Access lists recent files from servers or devices that are no longer available.
- Thumbnail and preview generation for large media folders overwhelms Explorer.
- A failing drive or corrupt system files cause reads to stall.
Why it matters
File Explorer is how most staff reach their documents, so constant freezes and crashes interrupt nearly every task. People lose unsaved work in dialogs that close unexpectedly, and frustration leads to risky workarounds like saving everything to the desktop. When the trigger is a failing drive, ignoring the slowness can mean losing data that hasn't been backed up.

Frequently asked questions
Is this a sign the computer needs replacing?
Usually not. Most cases trace back to software add-ons or network settings rather than old hardware. We check the drive's health as part of the diagnosis.
Why is it only slow in certain folders?
Specific folders often contain file types that trigger a slow add-on, or links to network locations that no longer respond.
