Special Character in Filename causing lack of syncing

Hello dropyak, welcome to the Dropbox Community!

Certain characters can be used on some operating systems, but not others. This also means that, while your files may be visisble on the website, they may not be on a computer that can't handle those characters.

In this case, you are right! The vertical bar you mention is an incompatible character on Windows devices. You can find more info about this, here. 

Let me know if you have any other questions, thanks!

Thanks, Lusil.

Does Dropbox give any notification to the user that a file wasn't synced? 

If I hadn't done a file-for-file comparison, I wouldn't have seen this; I can't imagine that someone with many more files than I would be interested in manually verifying the results of a sync.

I understand where you're coming from and, in general, to prevent sync problems in the future, make sure to avoid naming your files with any of these characters as Dropbox can't sync them on some platforms.

If you have any other questions, we're only just a post away, so just give us a nudge. 

In the meantime, I hope you have a lovely day ahead!

High marks for being polite. Low marks for the quality of the non-answer.

I take it, then, Dropbox does not notify - e.g. create a log - the user of any sync problems for subsequent follow-up? If that is true, on what basis can any business believe your service is reliable if certain files are not synced yet the user is not notified of this?

Surely this can't be the case.

Yes dropbox notifies you. There will be a red ! on the dropbox icon (at least on my PC there is).

and if you open the dropbox app, click on your initials and select "view sync issues" you'll see a list of all files that did not sync, and a short message as to why they didn't sync.

I am experiencing the same issues Dropyak is talking about, and there is no red ! on the dropbox icon as you say. As far as the "view sync issues", where exactly can I reach it? Since the problems we are facing are on a PC, there is no app to begin with. So, where else can we see sync issues?

I have only noticed not all the files were syncing by chance. I then compared the amount of files I have on my Mac, and there is a huge difference to those I have on my new PC. It means that a lot more issues like the ones I casually found out, probably regarding special characters Windows don't recognize as well, are still happening. But dropbox didn't notify me about them, and I still can't know which files are missing. Again, I only know they are missing because the total number of files is different from one computer to the other.

So, where exactly should I go in order to fix it?

On my PC, the dropbox icon is in the lower left corner. 

left click on the icon and then left click on your initials (upper right corner)

One of the menu options is "Show Sync Issues"

Thanks! The Dropbox icon was not visible anywhere, that's why I was not understanding your explanation. I had to made it appear on the lower tab first, and now I can do what you advise. I have 63 files requiring me to rename them now. After a few years using a Mac, it's good to be back on Windows and have an entire evening ruined like this.  

I have 59 files. But I decided I don't NEED any of those files and will leave them.

Have also alerted my co-workers about "special" characters and have requested that they not use them.

I see a large list of strangely named files in the "Dropbox Sync Issues" dialog box, but when I click on "Go to file", it opens an explorer window rooted at "This PC", and not the actual file on Dropbox. So, I have no idea where the file is located.
