Downloaded some photos from my (very) old Nokia.
Some I had already downloaded in the past and renamed them, adding a leading word Nokia to the filename.
When checking, I noticed that some of the downloaded images are having difference in file size compared to the existing ones, i.e. the ones that haven been downloaded in the past.
No big deal: it involves just a limited number of 'duplicates', all in the same folder, so they are quickly cleared.
Nonetheless I am curious to know why these files are different in file size.
In theory it could happen with hundreds of files and stored in my subfolders, i.e. removing duplicates (based on file size) may be more complicated.
