How do I permanently delete files, photos from sd card on Windows PC?
When files are deleted from an SD card, they aren't immediately erased; instead, the space they occupy is marked as available for new data. Until that space is overwritten, it's possible to recover the deleted files using specialized software.
To permanently delete files from SD card, you have to first use the large movies files to eat up the storage one more times. This will overwrite all existing data and make them unrecoverable. You can also do with a data erasing software.
Do deleted files stay on SD card? Yes, deleted files often remain on an SD card even after they are "deleted."
When you delete a file from an SD card, the operating system doesn't immediately erase the data. Instead, it marks the space previously occupied by the file as available for new data to be written. The actual data remains intact until it is overwritten by new files. This means that, in many cases, it is possible to recover deleted files using specialized data recovery software, as long as the space hasn't been reused.
This is why a single deletion or formatting won't permanently deleted files or photos from SD card card. To completely erase an SD card, you have to overwrite the current data with random files at least one time. Overwritten data is much more hard to be recovered!
