The next file is more related to menu's and configurations of steam but I have heard people able to resolve their issue by correcting this too.To refresh this file close steam and go to your steam directory (defaulted to C:/Program Files/Steam).
I spent an hour or 2 looking into various methods like: Clearing the Downloading folder of 570 (Dota 2) Clearing the along with Reverifying the files (did that each time i attempted to fix the issue) Trying to change what region it would download from I did the above with 0 results along with a few other things in what i had attempted.
I know this issue is reasonably common and has been around for quite a while and think it would help others to have another post added for this issue.
My friend's account is currently having this issue, his Dota2 update forced him to download Gigabytes of files, despite the fact that I only have to download around 200 MBs of files. And then Verifying the integrity of the game cache I guess it was probably because after the renaming and then comparing the files, i got a lot of files missing. I did everything but nothing worked please help ise only thing is install the custom modes to play with my friends but I can not download or install modes other games that have games.
Open the depocache folder and you will see a few files 571_######.manifest to 573_######.manifest.
These files are related to Dota 2 and can cause the download to stall.
