问题
I have an SSD as system drive (C:) and it's a real lifesaver, however the free space is a premium value here, so I wish to keep non essential files away from this drive.
One of the major disk 'eater' is the VisualStudio HelpLibrary used in Local Mode.
I have searched on the net, but with no luck, how to move this location (C:\programdata\Microsoft\HelpLibrary) to a different path on a normal hard drive (e.g. D:\HelpLibrary).
There is a way to do this with Visual Studio or we need to use some registry or config trick?
回答1:
The answer isn't really up to date anymore, at least not with my win8 VS2012 install. you can find the key here HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Help\v2.0\Catalogs and here HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Help\v2.0\Catalogs\VisualStudio11
I couldn't find the querymanifest xml, but I guess that isn't needed anymore. Since evrything is working peachy!

I have found the solution on this site.

I write here the relevant part of that article.
However I suggest to read it because there are numerous information on HelpLibrary settings
- Shutdown "Help Library Agent" tray application (of course, you can't change anything with this running)
- Find the current path of the help library store looking at registry value "LocalStore=" in HKLM\Software\Microsoft\Help\V1.0\
- Go to that folder and Move everything to the desired location.
- Update the registry value "LocalStore=" in HKLM\Software\Microsoft\Help\V1.0\ with the new path.
- Open the file manifest\queryManifest.??.xml in notepad and rename all occurrences of the old help path to the new path.
Tried and I was able to free up to 6GB of disk space on the SSD.
