Sometimes I would also delete a file, and whilst the file would be deleted it would still show in the folder view!
After a bit of digging, the following seemed to do the trick:
1. Backup your registry.
2. Edit your registry and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
3. Create the following DWORD values:
- FileInfoCacheLifetime = 0
- FileNotFoundCacheLifetime = 0
- DirectoryCacheLifetime = 0
