Library is too large to sync

I just installed SeaDrive 2.0.15 on Windows 10, sync with Seafile Pro 8.0.4.
Then SeaDrive gives a warning about one library is too large to sync. What to do now? The lib is around 170GB.

Will I need to split to multiple libraries?
What is the size limitation of a library?


I assume the library contains a lot of files/objects, right?

In this case, you need to set a parameter in seafile.conf: Seafile Professional Edition - Seafile Admin Manual

It contains nearly 200K files. I will try to change as you suggested.
