Improve the feature of synchronizing more than 100,000 items on a stable basis for OneDrive.
I am aware of the behavior the restriction mentioned that the sync performance will possibly deteriorate when the stored items in the library exceed 100,000 items more. However, I need to operate this process frequently so that I wish the feature will be improved enables sync more than 100,000 items on a stable basis as soon as possible.
Although I have concerns about if the synchronization is going to be impossible to proceed unexpectly, but so as MS described as "We are working on optimization of OneDrive to improve processing of many Libraries." below the Reference information.
Title: Restrictions on synchronizing files and folders
Thank you for your continued support.
We are working on changes to improve the experience when syncing large file collections.

Can we please get an update? We're considering archiving files that aren't ready for archive yet, just to get around this 300,000 file synchronization limit.

I've currently got over 200,000 files synced, maybe closer to 300,000 - OneDrive is almost unusable, it can take over an hour before it decides to sync up a handful of small text files (ie: 3 files with HTML+PHP code, each no bigger than 8KB)
Previously we used Dropbox which on a new machine would sync over 400,000 files overnight and would sync individual file changes so quickly I could hold a text-based conversation with a colleague just by editing the same file.
We switched to OneDrive two weeks ago and it has only just caught up with syncing with fewer files selected. Initially I tried to sync the same amount of files as I had with Dropbox and the app simply stopped working.
The OneDrive app (especially on a Mac) is terribly slow and cannot cope with a large number of small files. Dropbox worked very well so I know it can be done.
Apple are about to release BigSur, maybe that will help or maybe it will make things worse. Either way, the OneDrive app on a Mac is not suitable for syncing a large number of files.
Performance issues aside, the rest of OneDrive seems pretty good. We use Office365 on our Windows and Mac laptops and it has integrated well into that. The app and web interface is ok too.

Our libraries have grown to over 300k files that need to sync to user computers. Is there an update? Would love to see 500k+ as the limit.

Caution with files tagged as ~ .tmp;
They not working to the PC at cloud. Rename it

YEs, we are in the process of moving network shares to SharePoint. WE do as users to clean up files and we suggest to them to choose only folders they would like to sync, but we still run into issues where users select many folders and as well as their personal OneDRive exceed the best practice of 300k files. we have to run reset many times when it hangs up. thanks!

Large file libraries are a nightmare! My place of employment is moving its network storage into the cloud, and my computer is CONSTANTLY using large amounts of CPU usage. If I reboot the PC, it takes HOURS for the indexes to rebuild. I see "processing changes" constantly on the taskbar icon. It just doesnt work well for syncing large sets of data. I have 2 very large libraries that I have to maintain full access to. One is 148GB, with 33,552 files and 1,858 folders. The other is 365GB, with 529,150 files and 45,624 folders. These libraries bring my workstation laptop (i7-9850H, 48GB of RAM, and Quadro T2000 graphics) to its knees. Please fix!
It’s been a few day, my new computer is still “synching” the thumbnails.... MS needs to do something, it is 2020! Why not just prepackage them, download together and then update the new changes instead of one by one? Each one takes 1-2 second on a high speed connection.
Still nothing? This makes OneDrive almost unusable for me. I just renamed a folder by mistake, with ~200k photos, and OneDrive is unable to simply process those changes. It stalls and the only way to get it to work is to close OneDrive, start again, every 10 minutes or so. Unbelievable this happening in 2020. I just got Google Drive and will see if they handle these all too common scenario correctly.
Just think how many clients lost to DropBox and Google Drive because of this short coming.
If the /settings/***.DAT file exceeds 4GB One-drive completely crashes and no longer functions. I assume this is due to a large number of files in the one drive folder.
Allowing for certain folder exclusions could prevent this for many.
Can we get an update on where your up to with the improvements to large file collection syncs are yet - we have multiple customers who are now facing the issue as their syncing over 300,000 files -
It's becoming quite common for business data sets OneDrive to have larger than 300k files and our support desk is now getting calls regularly about this issue to which there is no resolution yet
Let us know, thanks.
In my OneDrive I have currently about 315000 files - on my private PC. When using OneDrive for business needs, I will have more. As a software developer working for multiple huge enterprises, I would expect OneDrive to handle multi-million files without any issues.

Any news here at all? This is ludicrous that you have gone so long without an update.
The fact is, Onedrive syncing is just broken on large file counts - even some of our libraries with only 40k items suffer.
Dropbox has high IO on mechanical drives, but, a NVME fixes things and it can run very well with a library of 900k files, and likewise, not seen any problem with Google Drive.
The shocking thing is, Onedrive appears to work quite well on a Mac, but, it just seems that you can't get your act in order on Windows which makes no sense at all.
In fact, I would go to say that third party apps that mount Onedrive as a network drive do the job "ok" and I would say that you really need to reintroduce this feature in a supported way as it is so much more reliable.
We are on the verge of moving away from Onedrive and to Azure Files or back to a third party tool as we can't go on with this...
Microsoft, what is your status on this problem? We have been suffering with sync breakdowns for 2-1/2 years now. Files On-Demand helped but did not solve the problem, and we have suffered data loss because of the problem. Sometimes, the sync becomes so broken that it simply gives up and starts over, but gets no farther the second time or the third, and a user's local changes will never be synchronized to SharePoint Online. Office 365 Enterprise Support always refuses to help us collect data that you could use to diagnose the problem, and their solution is for us to disconnect the sync, delete the local files, and reconnect the sync, which means a lot of lost data and productivity each time.
Having some idea of what you are doing to work on it or a timeline when you anticipate having the problem fixed would be helpful. We've been begging for this to be fixed since June of 2017.

A restriction of 300.000 files is just ridiculous. As one of the leading companies in terms of modern cloud based Data-Pools Microsoft certainly has to push this topic even more. This is next step for many companies to get rid of old server-structures. ODFB is a great tool for simpliflying processes and push the acceptance for the older generation to work with the cloud.
@MS this is your chance to improve work sustainedly
Unfortunately I read this article after we did a big migration from a file server to SPO.
We got large Performance Issues with ODFB when we synchronized 450.000 Elements from SPO to the client (Files on Demand). The speed of the initial sync was OK but when we worked with these files, we had to wait 20-30 minutes until new / edited Office files were synced to the clients. Not acceptable for the users. In our misery we started to sync all Documents with OFDB on a fileserver again and connect the users via file share to the documents. We had to rebuild all Permissions and so on …
Very bad situation because we see a great potential in this way of syncing, and it is of cause one huge advantage of ODFB / SPO. But now we a really frustrated. Hope that MS is improving ODFB soon!!
