tldr; I was wrong. WinDirStat was reporting file on disk incorrectly for long paths. SeaDrive was clearing files correctly.
New user to Seafile, have upgrade to recent Docker CE 9.04 on Ubuntu Server 20.04 and Windows 11 Seadrive Client 2.0.19.
I have a number of large libraries >1.5 TB (~5TB total). First sync for all the libraries was via seaf-cli on the backup HDD also running on the server.
When using Seadrive on W11 client, Seadrive downloads and keeps all files with long paths and filenames on the computer. Even if I set the cache size to 1GB, these files are not unsynced (uncached? not sure how to say).
Is the only solution to rename my files or is this a bug in Seadrive?
