Can I remove files from upload directory?

What will happen if I remove files that have been in the upload directory for some time (weeks).
I noticed that the files seem to be corrupted, like only half the image will load (or the video will not play at all). I also noticed that a lot of files are quite large (by my library standard) 1gb+. Which led me to think that some sort of network problem may have stopped them from uploading correctly? Will any missing files be uploaded automatically from mobile devices? or do I need to identify the files and try to upload them manually?
