So I recently quitted Google Drive and downloaded all my data and hoping to keep it on Hard drives myself, They are external plug in types and I want the files synced like it was on my computer. So when I plug it in it copies/syncs the things on my computer, anyone knows somethign like that?
I use freefilesync. You can tailor what is copied where and save it to an executable batch file. If you want to trigger the batch file when your external drive is plugged in you can create a udev rule. Best is you look that up yourself, since it heavily depends on your system (no chatgpt tho!).
