I do a lot of freelance work that often involves transferring large files that don't compress well or at all really. Security and speed are of most importance. I'm somewhat tech savvy, but I'm by no means a full stack developer. Anyone else here have any success transferring a lot of files with few issues? Free or paid solutions will work, but nothing exorbitantly expensive please. :-\
