timppu: I was originally thinking I'd wait for the new gogrepo which hopefully has the ability to divide your GOG collection to different paths (in my case, to two 2TB hard drives).
kbnrylaec: I guess any Unix-like system wth symlink support would do the trick. :-P
I think I got the same proposal earlier in this thread, but apparently it is not a feasible solution:
https://www.gog.com/forum/general/gogrepopy_python_script_for_regularly_backing_up_your_purchased_gog_collection_for_full_offline_e/post406 Or did you have something else in your mind which was not already suggested in that discussion?
Someone else also suggested manually dividing the full manifest file into two or more parts, and then running gogrepo download (or clean, or verify) separately for each of them, using different paths. I guess that would work, but then I need to do it manually each time (dividing the new manifest file into many). As a matter of fact, I should have tried it this time... oh well, next time then, or maybe this functionality already is in gogrepo then.
EDIT: Now that i think of that "dividing the manifest file into two" suggestion... it starts to sound quite good because with it I could easily maximize my download speeds with my two separate internet connections.
I've mentioned before that I have a fixed 10Mbit/s cable modem, but also a 4G LTE (unlimited) mobile connection which here can reach up to around 60Mbit/s (sometime less, even down to 10Mbit/s; the best I've gotten with it was well over 100Mbit/s, but that was outside my home).
I tried earlier combining those two connections into one in Windows (internets has many suggestions how to achieve that), but I couldn't really get it to work, I'd get the bandwidth only from one connection at a time even though both were supposed to be active. However, if I divide the manifest file into two and run gogrepo on two separate PCs (one for e.g. games starting with A-N, and the other for the rest)... then I could use both of my internet connections to the full at the same time! Why didn't I think about this earlier?
