While attempting to move thousands of files from internal storage to an SD card, Solid Explorer halts and gives up when it encounters files that cannot be deleted from internal storage after they're copied over. SE cancels the entire move and posts an error. It would be far better If SE could offer to continue when a delete fails. Copying 100% of the files to the e SD card with an estimated 2% not deleted from internal storage is much better than just giving up.
