OneDrive for Business file limits

Can someone give me the definitive answer on ODfB file limits? Is there a 20,000 file limit as far as sync is concerned, as far as total storage (even with a 1TB total space limit), or are those numb...

You hit the nail on the head for the issues we have been experiencing. We probably have upwards of 400,000 files. Though not every user is syncing all of them, but at least around 100,000. We have 1GBs bandwidth and the majority of our PC's are newer with SSD's (we have found that we have less sync issues on SSD's then traditional HDD's)

Do you know if the issue is the amount of files the user is syncing to their desktop, so unchecking unnecessary folders under "Choose Folders" in the settings would improve the syncing issues. Or is it just the amount of files in the that are in the sharepoint library, whether or not they are synced?

Nathee021 - the limit is currently 300K files syncing. If you have more than that, MSFT warns OneDrive sync client will perpetually be looking at files for status change and therefore perpetual loop. I have one user with 1.5M files, but we only sync about 250K and it works fine (so sync folder selection helps w/ issue).

but when you have millions of files OD stays in a loop and never gives you the list of folders to pick

Hey -thanks for your comment,

I had a couple questions:

1 - is this 300,000 per document library - or - in TOTAL that can be synced?
2- Do you know if that would affect "Files-on-Demand" i.e. A user Syncing 3 or 4 document libraries with over 150,000 in each (total 450,000) but all in "File-On-Demand" so not actually syncing.

Kind regards

  #1 - 300K TOTAL across all sources #2 - FonD does not impact this total Issue is not the time to sync the files, the issue is the time it takes to look through all the sources to see if sync of any files needed. As a result, as you get over 300K, you may see perpetual spinning sync icon.

    I have experimented, and If the Library has over 300k records than it is very slow. So, if you have a single file library with 1 million records, and you try to only sync 250k of those records, it seems OneDrive still loops through all 1 million records at initial sync. This causes huge performance issues.
