I have around 20TB of photos, nested inside folders based on year and month of acquisition, while hoarding them I didn't really pay attention if they were duplicates.
I would like something local and free, possibly open-source - I have basic programming skills and know how to run stuff from a terminal, in case.
I only know or heard of:
But I never used them.
Know that since the photos come from different devices and drives, their metadata might have gotten skewed so the tool would have to be able to spot duplicates based on image content and not data.
My main concerns:
- tool not based only on metadata
- tool able to go through nested folders (YearFolder/MonthFolder/photo.jpg
- tool able to go through different formats, .HEIC included (in case this is impossible I would just convert all the photos with another tool)
Do you know a tool that can help me?
