Will my regular Dropbox folder be converted to a junction point after an update on the Windows app?

Frank P E.

I hope I can get some insight in this forum — It seems that regular support is not equipped to respond to these very technical questions

I noticed that the window’s file/system explorer added a new column called “status” — it reflects the statues of the files managed by cloud storage which is used by MS Onedrive. This process is handled by the Windows Cloud Files Filter Driver (CldFlt.sys).

It seems that recent installed of Dropbox on windows, it is using this API. The “tell” is that the “Dropbox” directory “looks like” a junction / reparse-point that is pointed to itself.

My Dropbox folder is around 100g, but my friend’s Dropbox folder is over 800gb with over 800,000 files. He is still running on win10 I am on win11 — my Dropbox folder look like a junction when my friend’s folder is a regular local directory. We are both on same version of dropbox.exe

From what I can find out is the “status” column will be blank if the Windows Cloud Files Filter Driver (CldFlt.sys).is not used

So, when Dropbox does it regular update, will it convert the regular local Dropbox directory to a junction to use the Windows Cloud Files Filter Driver (CldFlt.sys).

Hi from me as well, @Frank P E..

The update you're referring to, is the new Dropbox for Windows update, which is indeed utilizing the Cloud Files API.

If a computer is using the Cloud Files API and is eligible, the Dropbox app will automatically update to that new version at some point.

You can read more about this update here and here.

I hope this helps!

Hi @Frank P E., thanks for taking the time to message us.

Could you clarify what you mean in more detail? Does the CldFlt.sys file not load for you sometimes, causing you to not see the sync icons?

Are you on a personal account, and were you ever part of a Dropbox team at one point, since there is a small possibility a junction point was created from the team?

If you can share any messages, logs or OS/Dropbox specs, that'll help me narrow this down much faster.

Thanks for the reply –

This is a simple question ---- The “status” column in the file explorer is only filled in if Windows Cloud Files filter driver is set up for the cloud provider, ie Dropbox, Onedrive

Recent installs of Dropbox do setup the Dropbox folder to use the Windows Cloud Files filter driver where in the past the Dropbox folder was just a regular local folder on the hard drive

So my question is for older installed of Dropbox where the Dropbox folder was just a regular local folder on the hard drive will it be automatically converted to use the Windows Cloud Files filter driver when Dropbox is updated and now make the Dropbox folder look like a junction
