Dropbox Link Broken When Overwriting File

This is also happening to me and I've been scouring these threads for answers. I work on a Mac and primarily share files created with Adobe programs like Illustrator and Photoshop. My primary reason for using dropbox is that I can email or share a dropbox link, and then can edit the file and save within illustrator or photoshop and the link remains the same for the end user. I constantly use keyboard shortcuts within my software to save while editing, so exporting the file and then uploading to dropbox online is simply not an acceptable solution. I've tried the work-around of exporting and dragging the file with the same name into the folder, but that doesn't work either. Even if it did, it's far too cumbersome to be helpful.

Here's a step by step example of how it happened today...

• I was chatting with my boss and dropped a link for him to view a file "Beast Apparel.pdf"
• After putting the link in the chat, I clicked on it to make sure it was live and review. The link worked fine, but I noticed a small error. I still had the file open in adobe, so I very quickly made the edit and used the shortcut to save the file. 
• Minutes later my boss says "dropbox says your file was deleted"
• I copy the dropbox link again and sure enough, it's different

This is a HUGE issue for me. I have hundreds of shared file links across google spreadsheets, Asana (used for project management), in emails, etc, etc, etc...if all of these links break every time I edit and save, I will have to find an alternate solution to dropbox. 

Has any solution been found?

So I knew the deleting files thing was happening...interestingly enough, I did some more testing and it seems NOT to occur when saving .ai files, but does when I save as a .pdf . I primarily use .pdf because it doesn't change the editing experience for me, and is accepted across a wider range of applications. Plus the .ai scares off my co-workers even when it's pdf compatible...

I tested out the "do not sync" button in my right click file dropdown, then saved my pdf file while using illustrator as normal. Interestingly, the file re-syncs right after saving, but the share link STAYS THE SAME. So you're right, it's definitely the speed of the dropbox sync that detects the deleted file...

I can try to remember to always unsync when saving my files...this is better than the online upload alternative, but still pretty annoying. Any idea why this was not happening for years and years and suddenly became an issue? Also I wonder if dropbox could somehow program a short delay in syncing, or delay the deletion of links when a file is deleted to see if one with the exact same path and name pops back up in a millisecond. That's above my pay grade, but I'd love a solution that doesn't rely on my remembering to unsync or whatever before every file edit / save. 

Aaaaaand now after messing with this for literally hours today, I am no longer able to replicate the issue. I think my "fix" had something to do with messing with my file finder settings of "show all file extensions". My only guess is somehow the extension was getting written into the name and causing a delete > new file issue? No idea, but no matter how hard I try, I now can't break the links simply by saving alone. 

Hi!  I'm currently having this same issue.

"

Let's take PDF's for example. Normally, I could simply update a file/make corrections to it - save and close and that file would sync.

So the next time anyone who had the link opens it again, would open or view that updated file.
What is happening however is, when a change has been made to the file and closed - the link that was originally associated with that file no longer works and points the viewer to a page saying it has been deleted."

Yeah I'm back to having this same issue, as well. It was fixed for maybe a day on my end. I'm no longer using dropbox links to share any of my files unless I keep them in a separate, dedicated folder that I know not to edit or re-save, and can also no longer use the old links that have been shared for the past 5+ years in my company-wide Asana project management system as reference. Many are useless now, so I'm just uploading files directly. After about a decade as a happy dropbox user, I will likely end my subscription if this doesn't resolve soon. It's the only feature I need.
