Let's Explain Episode #1
Now I'll explain you how I upload my modpacks. I do it complitely free, and that's how it should be.
But free = limits.
I'm using Dropbox right now to upload my modpacks, so I'm limited to about 2 Gigabytes of space. And it's for this reason that I can't leave the previous version on the cloud.
Once I publish a new version, the older version remains as a backup. If I see that the newest version works perfectly, I remove the older from the cloud, gaining some Megabytes of space (~23-35 MB), which can be used for new versions and new modpacks.
Keep in mind that in the cloud there isn't only the modpack, but also the server of the modpack.
After this, I want to talk about Manual Downloads. I put the manual downloads on this website so that everyone can download the modpack and put that in their personal %appdata%/.minecraft/mods directory.
But I need to have users' feedbacks on my modpacks; and I have the feedbacks only by the Technic Platform.
So, from now, if you want to put my modpacks' mods into your personal minecraft directory, just go into %appdata%/.technic/modpacks/(my-modpack-name)/mods and copy-and-paste the mods into your personal directory, %appdata%/.minecraft/mods.
Thanks for paying attention, LuigiGrande1.
