What's With File Uploads for New Projects

I am pulling my hair out and banging my head against my PC desk. Why can’t multi-part archives be accommodated (with extensions 001, 002, etc.)? Why does the damn site wait until AFTER you’ve spent upwards of 2 1/2 hours uploading the parts BEFORE it tells you they don’t have the right extension?

Just wasted all that time because I split the slightly less than 2 gig 7z into 4 parts. This being because I currently have an intermittent drop-out problem with my internet connection (it took 2 tries to post this) and I figured that at least some should get through without being borked.



Now that I’ve cooled down I have successfully used ftp/attach to get the 1.99 GigaByte file uploaded.
