after syncthing -reset-database index-v0.14.0.db is 32Mb

-reset-database deletes the db so it’s sort of expected that is has gone down. Did it stay like that after scanning all folders?

How many files/folders are we talking about here?

How many devices connected?

Did they (all of them) reconnect to you since resetting the database? If yes, what’s the db size then?

What does the database look like in terms of size on other devices?

Did it stay like that after scanning all folders?

before -reset-database I pressed Rescan All but nothing has changed.

How many files/folders are we talking about here?

6 synced folders

How many devices connected?

There only 2 devices pc and phone.

Did they (all of them) reconnect to you since resetting the database?

Yes!

If yes, what’s the db size then?

32Mb.

What does the database look like in terms of size on other devices?

The other device is only android, I don’t know how to check it there.

Did you rescan after the db reset?

Do you still have a copy of the old database?

What number of files/folders inside those 6 folders?

Did you rescan after the db reset?

Yes

Do you still have a copy of the old database?

No ):

Presumably the other side should have the same database in terms of size if it was not reset.

This could have been caused if you had a large number of files that were later deleted, as items are never removed from the index.

Other than that, it’s hard to say or understand given the evidence is gone.

What number of files/folders inside those 6 folders?

4500 files in 363 folders takes 34.05Gb total

/data/data/com.nutomic.syncthingandroid/files/index-v0.14.0.db is 25Mb

Right, see if you can get your hands on a db, as now the evidence is gone, so hard to understand the cause in order to fix anything.
