is it safe to share the indexes folder between computers? my understsanding is the indexes folder is created if you have tindex set to 1 and want to keep an index of all transactions. all of the material i've seen (bitcoin core documentation, on this site, etc) either:


says it's safe to copy only blocks + chainstate between computers
lists files + folders which are expressly unsafe to copy (ex. wallet.dat).


my understanding + intuition of the indexes folder (from docs + inspecting the files myself) is that it has no pii and should be safe to copy but i just wanted to confirm.
Yes, indexes is safe to copy. It only contains transaction data and is completely unrelated to the wallet. In fact, indexes used to be part of blocks so with older versions, if you had txindex=1, then copying blocks meant you also copied indexes. Only recently was this separated into its own folder in the datadir.
