I need Dropbox files redistributed between two drives, due to the lack of space.

Hello Nancy​ .
Thanks for your answer.
Trying to answer you + adding some finding + discovering Dropbox stupid issues

* Updates:  None for what I know.

I was just able to Re-Start the Main-PC yesterday, from the previous crash.
Having now diagnosed the USB-PORT-HDW issue. Removed the connected device. Used a USB cable to test it... result: plug anything in that port and you get a BSOD.

When I rebooted and entered the PC, I've got the first Dropbox warning: "not enough space" Quite surprised I went to settings and provided to put 60G "online" for letting him work.

That warning was a big surprise to me:
  ----> nothing was wrong before it crashed!
In any case, that raised the first issue in the OP:
I need two disks to do what I was doing before one 1Tb § no reason given §

* Existing version, no idea! but please look at the bottom of this reply.

When your reply was notified I was already uninstalling it for the third time. Downloading it  from WEB
> NO MICROSOFT STORE INSTALL

__________________________________________________________

For the First time I've got a lot of issues installing
- some quite stupid as you will see below :-(

_________________________________________________________________________

* First my finding for <maybe> a reason to understand Syncing issue...
... on Main-PC [T24 / TwenyFour]  vs BKP-PC [Q12 & Qanto]

Dropbox continued correctly to operate from BKP-PC for several days keeping  updated local files in Sync with the Dropbox-Cloud

SO 

No idea why because it was a first time:
.. a lot of "conflicted files" were present in MAIN-PC Drobox!!!

[deleted them all - while I was Already uninstalling]

_____________WARNING STUPID ISSUES AHEAD ______________________

Note: I'm a long time user.
 I've reinstalled Dropbox several time... Never encountered them!

Title: DROPBOX FOLDER NAME 

Usually when you reinstall Dropbox, it will recognize its own folder,
accept it as it is and proceed or ask you if it will have to "Merge".
Not This Time
____Let's start from the beginning.___

The folder location has become   > E: <    all ORIGINAL files are stored on Disk

 * Removed "save offline"

WARNING        ---> MAIN CRAP AHEAD <-----

* Removed "Windows integration" 

THAT WAS CAUSING THE SYNC LOOP

I'LL NEVER USE SOFTWARE WRITTEN FOR MS ONEDRIVE EVER AGAIN
[Just to inform you]
...If you insist using MS garbage instead of your fully secure software ...
>>>>I will find another solution and leave DROPBOX TO HIS FATE <<<<<

I cannot put in danger my business files

And I get [again] the same Warning

I "choose folders"  reducing the Space Needed ...  by putting 60G in "offline" mode


______________________________________________________________________

____ first silly message_____

🤢

______ Why "RENAME"  instead of "MERGE" or NOTHING at all ________

as it was expected _____ and the normal behavior in previous re-install???

What's that!!!!!

( ok ... found the culprit: a utility was using per usual a Dropbox sub-sub-subfolder to keep updated settings) 
As I am an experience PC Manager ...
 I used ResMon > Handles search > ID the Process + terminated it
Via FileExplorer I renamed it DROPBOX_OLD

Now I need the files in the version already on the disk -- How to do it 😇 ---

SOLUTION

* Kill the Dropbox APP after the full Setting and before it start Syncing
* Move all the DROPBOX_OLD contents to  the new created folder
    this way:

* Launch DROPBOX AGAIN

* Enjoy a fully operating Dropbox as it would had been the "MERGE" option

  <<>>SMILE AT THE STUPIDITIES YOU WERE FORCED TO GOBBLE DOWN<<>>

And LO ... they keep coming in full moron's behavior!!

WHY I SAY SO?

In 2025 Dropbox developers keep using a fixed  error's window, not resizable !!!
... and containing unusable garbage
[yes, garbage]
- you can't even understand the file name with sync error in what folder is located!

[if you click on the error message it will open a FileExplore that bring you to "MyPC"]

I've no idea why a so beautiful piece of software...
>that helped me for more then 10 years without big faults<
...is starting collecting "Stupid Attitudes" and "Moron's Behaviors"

-__ in 2025 this is the 5th IMPORTANT Issue I've suffered - Just in 7 months __-

( let me know how more I can help you )
