just had the pleasure of using the itch.io client in the current version for the first time.
I proceeded to reinstall the AvenColony installation on another harddrive (which was set up as the _DEFAULT_ install dir in the itch-io client). After an hour the download finished in the background, did something random and then installed nothing.
The drive I was forced to install the itch-io client upon (C:) was/is full with the download completely unpacked unto my system's SSD.. there's a 2.7 GB download in the default-install location/downloads/ directory, which is obviously not enough and thus fails to unpack.
My C: drive is stuck at 20 MB of free space, and I have no idea where the itch-io client decided to waste the about 10 GB of free space before starting the 4.7 GB download. The usual suspects (windows-temp, user appdata-local-itch, etc.) don't contain the files.
I just found you are using the roaming-directory/itch/ to contain the download archive while downloading, and you also unpack the whole frigging (in this case) ZIP archive in that directory... WHILE you are installing the game to a wholly different drive. Did anyone think this through?
--- Found out myself where it clutters up my system harddrive..
* WHY doesn't it clean up after itself when it is done ?
* And why does it not resume partially downloaded files, but instead redownload everything from scratch ?
Also, you can't limit the bandwidth usage, same as with the GOG Galaxy client, so you are in good company there ;)
