It would be great to be able to ignore or exclude selected files and folders within the OneDrive folder from syncing. It has been requested a few times before and solves user problems in a variety of areas: from software developers having problems with temporary build files and node_modules folders, through users who want to ignore sync problems (or issues like waiting days for a file to upload on a slow connection) by ignoring files in sync, to users who want to ignore files and folders created by applications, especially photo applications. There are many use cases where this feature would be a solution.

It might also be the case that a feature would reduce the number of support requests and user dissatisfaction, since users would have a way to fix various issues themselves (there is probably more applicable scenarios than described above) by desyncing a file or folder causing problems.

I know this feature has been requested before, and has received the status 'not right now', therefore I have termed this request 'reassess', to determine if the 'not right now' status is still the state of this feature request. I have collected the IDs of the uservoice requests for which this feature would be a solution (listed at the end of the request), summing the votes on these requests, this feature has a total of 549 votes, which would place at about the 35th position, among other requests which have status of 'working on it' or 'thinking about it'.

Thanks for your consideration!

The IDs of the related uservoice issues are: 6988070,10720758,10932591,10778649,10954851,11301837,11344905,11654178,13452462,15748891,17236724,8026992,15017205,17169314,18429295,7290507,11625105,12915153,13541754,16044514,7927728

I'm currently uploading a high amount of data (I selected all the files I wanted and copied them to onedrive folder) and it's taking a lot of time. The problem is that some files are more important to me than others and I need them to be uploaded first. It would be great if I could make certain files/ folders that are being uploaded a priority so that those files with higher priority will be the first uploaded (for example, bittorent has this option when downloading files). It would take me a lot of time to cancel the upload and just copy/paste each file in the order I want them to be uploaded.

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.

Thank you for your continued support.

I am not sure I am at the right place to post this, but since some Microsoft engineer said here would be a more appropriate place for my post in Microsoft Community, here it goes (don't shoot me if this is considered cross posting):

Prior to installing the Fall Creators Update on my Windows 10 machine last week, all my files stored in any of my OneDrive subfolders were indexed and fully searchable through Windows Search. For example, entering ‘content:management‘ in the upper right search box would return all the documents (PDF, Word, etc.) that contained the word ‘management’.

Right after the installation of the Fall Creators Update, none of my files were found when using Windows Search. Either the index was deleted or, to paraphrase Microsoft support people, the option was removed ‘by design’.

However, as I continued to use my machine, I would try to search occasionally to see if perhaps the indexed had been rebuilt. Windows Search would slowly return more and more results as the days went by. I thought the index could not be rebuilt so slowly, one file at a time over the span of several days. At this pace, it would take months to index my 50 GB of files in my OneDrive folder! Today, I discovered as I open files from my OneDrive folders, they are indexed on the fly and thus made searchable by Windows Search.

Is this the new way OneDrive files are supposed to be indexed? Who thought one would only be interested in searching files he or she had previously opened, disregarding the others? While I do understand that the indexing engine cannot index a file not kept on the device (ie. on demand files), is there a way to force the indexing engine to ‘pick up’ all the files that are always kept on the device without the need to open them one by one?

追加した所有者でも、OneDrive 上のファイルにマウス カーソルを合わせた際に "閲覧者名" を表示できる機能の追加をお願いします。​

When you hover over a file on OneDrive with the <a0> OneDrive Admin Center </a0>-[show user name on file as owner] setting selected, the "viewer name " is displayed, but the site
You add an owner in the collection's administrator settings, and the owner you add does not display the viewer name when you hover over the file on OneDrive.
If you added the owner, please add the ability to display the "viewer name " When hovering over the file on OneDrive. * This feature is very useful because it makes it easy to check what files the user is interested in, so I hope to extend this function.

It would be nice to have an option to have OneDrive app prevent the computer to go to sleep until sync is done.

Typical situation is when you just added a large flie/folder to your computer and it will take time to upload. The computer is likely to go to sleep before sync is finished, and in consequence files are not online as fast as you might want. (and/or you can't just let your computer upload at night when bandwidth is not needed)

It would be nice to add an option to have OneDrive preventing computer to go to sleep until sync is fully done.
