WebDAV cache
The Windows WebDAV redirector keeps a cache of its own, shared by every WebDAV drive on the machine. The WebDAV cache tab shows what is in it and lets you clear it.
Tip
TL;DR — Settings → WebDAV cache. The overview needs an elevated helper, so starting the watcher asks for administrator rights. Clear cache empties it now; Clear cache on exit empties it automatically when the watcher stops — useful on a shared machine.
The redirector stores what it has fetched in a cache directory belonging to Windows, not to NcDavTray. Entries are named by UUID, so the directory tells you nothing by looking at it — which is precisely why the tab exists.
The tab shows:
- every cached entry, grouped by type,
- the total size and file count,
- live updates while the watcher runs.
Reading that directory needs administrator rights, so the overview runs in a small elevated helper process rather than elevating the whole application. You start it from the tab and it asks for elevation once.
Note
The watcher is optional and NcDavTray works completely without it. It exists for visibility — it does not affect mounting, connecting, or anything a mount does.
Clear cache empties the redirector cache in one click, without touching the WebClient service or unmapping your drives.
Clear cache on exit does the same automatically when the watcher is stopped.
Important
This is worth switching on for privacy on a shared or untrusted machine: whatever you opened through a WebDAV drive has left traces in that cache, and they are not removed when the drive is unmapped.
Caution
The cache is shared by all WebDAV drives on the machine. Clearing it affects any other WebDAV connection too — they will simply refetch, but a large transfer in flight elsewhere is not something to interrupt casually.
