What this does
Selective sync can hide folders locally while they still exist online, which feels like missing data.
Selective sync can hide folders locally while they still exist online, which feels like missing data. These long-tail cases are often hard to find because the visible symptom is narrow, but the root cause is usually a mix of settings state, driver behavior, cached data, or permissions around onedrive backup.
In plain language, selective sync settings do not match what you expect matters because onedrive and backup state is inconsistent after a restart, driver change, or update. People usually start looking this up when settings, services, cached state, or permissions around onedrive backup are not aligned.

How and why
In practice, selective sync settings do not match what you expect matters because onedrive and backup state is inconsistent after a restart, driver change, or update.

These long-tail cases are often hard to find because the visible symptom is narrow, but the root cause is usually a mix of settings state, driver behavior, cached data, or permissions around onedrive backup. A good next step is to review know which folders are redirected into cloud backup before moving them by hand. Then decide whether you only needed the explanation or whether you want a practical action page too.
You normally review selective sync settings do not match what you expect when you want to understand what Windows is doing, what changes it can influence, and whether it is relevant before you touch settings blindly. Useful things to notice first: know which folders are redirected into cloud backup before moving them by hand; keep enough free space both locally and in the cloud account; rename or move heavy folders carefully when sync is active.
- check whether the issue is sign-in, sync, storage, or backup redirection
- test with one small file before making many changes
- review cloud storage quota if icons look fine but syncing never finishes
- pause and resume sync once before unlinking the PC
- use the stronger reset, reinstall, or cache rebuild steps only for the exact failing feature
