Syncthing lims & caps

[kluppy]

Got me wondering…

Syncing large files, "Scanning", then nothing?

Ah. Figured it out. We currently only handle up to 128 GiB files, due to a limit on the length of the block list. Ideally, to handle larger files we should have variable (larger) block size, but in the meantime we can increase that limit. Although as you’ve already noticed the work required to figure out what actually changed when there’s an update to this file makes it somewhat impractical even when we fix this…

This is all I could find but one of the Devs may step in… I didn’t check the docs.
