Deleting files on SD card does not free up space on SD card

[patrickdrd]

I'm facing this issue: https://www.reddit.com/r/GalaxyS7/comments/5dpuqi/deleting_files_on_sd_card_does_not_free_up_space/

when I delete a big folder, it's not deleted, but moved in "system data" instead, I remove the card, I plug it in my pc and my pc says that the device has to be checked for errors, it runs the check and then creates a folder named found.000, if I delete this, the free space is regained! I've already formatted my sd card, same issue happened!

the strange thing is that this happens only with large/huge files and folders, if I delete some megabytes, not a byte is added in system data! so I think I need to think why could this be happening with large data

You're not deleting files or folders, you're doing something else. Android doesn't move folders to system data, it unlinks them (which is what "deleting actually is). Whatever 3rd party app you're using to "delete" them isn't doing it. Use My Files to delete things. (Or, at worst, get a terminal app, learn to use it, and rm the file or rm -r the folder.)
