Unable to sync 3 files in dropbox

[Ben Riv]

Hello,

I am really stuck on this. I have Laragon installed on 1 windows pc sharing dropbox.
The sync software wont sync these 3 files.
mysql/ibdata1
mysql/ib-logfile0
mysql/mysqld.log

It says the files are locked.

So I thought first that a background process(mysql) was running but no..I also cannot start mysql, it keep saying "initializing data". So I think that on this pc, it is not receivin these 3 files which causes the crash in mysql startup.

But why these 3 files are stuck in the cloud?

What could cause windows to not give access to these files in Laragon please?

Thank you for your help.
