Upd-2 (2020-11-27): so far so good, everything flies fast.
(win 10 pro 20H2 v10.0.19042)
No major changes. Possible suspects:
- I stopped synching photos from iPhone long time ago;
- minimized number of folders which synch locally;
- uninstalled adobe reader long time ago.
Update-1 (2020-08-30): the problem is no longer reproduced. Don't know what helped. Magic 🙂
No major updates were made (same win 10 pro 10.0.18363 / v 1909).
== Will keep the original post for a while ==
Below I speak about locally cashed filed and folders. Windows 10 and OD are fresh to current date. I've reset OD (several times actually, reinstalled etc), and the problem persists for 1-2 years (thru many updates etc)…
As subject states, many operations are extremely slow on OD folders.
- Most smaller folders open instantly, but some (normally bigger with images) open for 10+ sec.
- Initially I've noticed the problem with images – opening a picture takes 10+ sec. I blamed XnView but it's not the problem.
- OPENING MOST of the IMAGES from a OD folder (from Explorer etc) takes same 10+ sec.
- Select All (Ctrl+A) on a folder with images takes MINUTES…
- After selecting all images select any menu or right-click – 1 minute.
To reproduce:
- Reset OD, (fast)
- Sync only photos folders, (fast).
- Open a folder – takes 1 min,
- select all images (Ctrl+A) – 1 min,
- Right click – 1 min…
Stopping sync on any step – doesn't help.
Copying folders outside OD root folder – helps immediately. Everything works immediately (momentary response), like it should be. As such, problem is somehow related to OneDrive.
Anybody experiences the same? Any ideas why?
PS. And I'm not talking about Word/Excel, which opens locally synced OD files slow (office Apps check the file online for recent updates, and it's OK).
Win 10 Pro, Version 10.0.18363 | v 1909.
Personal OneDrive, v 2019 build 19.222.1110.0006.
Files/Folders are already locally synched.
I use Explorer or TotalCommander.
Fast Internet (60 Mbit both ways – shouldn't be the problem).
SSD, 75 Gb free… modern PC (i5-5300U CPU @ 2.30GHz, 2295 Mhz, 2 Cores)…

I had the same issue with a large OneDrive folder (several thousands of files) in a user (non-admin) account.
Finally found out that there seems to be a conflict between MacriumReflect (Free Edition) and OneDrive.
Uninstalling Macrium Reflect from an admin account fixed the problem.
The problem was simply reproducable by trying to open any folder inside the OneDrive folder (or the OneDrive folder itself) by double clicking it in Explorer or by trying to open the context menu. Both caused the Explorer to freeze for several tens of seconds. Uninstalling OneDrive (and rebooting) made the same folders responsive again. As mentioned by user1143638, navigating the folders worked without delays using the navigation bar left from the main windows.
After uninstalling Macrium Reflect and switching (log off/on) from the admin to the user account, the problem had disappeared completely.
I identified Macrium Reflect as the potential culprit by using Microsoft's (Process Monitor) (https://docs.microsoft.com/en-us/sysinternals/downloads/procmon), which always showed a remarkable amount of Macrium events when right clicking on the OneDrive folder.
The following changes (which I tried previously) all were without effect:
