Nextcloud asked in a poll at https://mastodon.social/@nextcloud@mastodon.xyz/115095096413238457 what database its users are running. Interestingly one fifth replied they don't know. Should people know better where their data is stored, or is it a good thing everything is running so smoothly people don't need to know what their software stack is built upon?
It’s important if you’re using flash drives across platforms though that’s pretty rare these days too. My wife has run into this problem by formatting as ExFAT (GUID partition table) when print shops’ terrible machines only support FAT32 and/or MBR partition tables.
Thankfully macOS at home understands ExFAT otherwise those formatted drives from her Windows work computer wouldn’t even work.
