Freeing up much space by creating a dyamic link.
1. It is assumed that the original installation is under C:\Program Files\ although it could be under C:\Program Files (x86)\. Make the change accordingly.
2. Create the folder D:\Adobe\ and make sure that you have ownership and full control permissions. Check Properties | Security | Full Control Permissions.
3. Open Command Prompt as an Administrator. At the Command Prompt, type the following four commands one after the other.
> ren "C:\Program Files\Adobe" "Adobe.bak"
> robocopy "C:\Program Files\Adobe.bak" "D:\Adobe" /E /ZB /DCOPY:T /COPYALL /R:1 /W:1 /V
> mklink /J "C:\Program Files\Adobe" "D:\Adobe"
> robocopy "D:\Adobe" "C:\Program Files\Adobe" /E /COPY:SOU /xo /xn /xc /xx
4. Make sure that everything works fine (try also conversion to PDF from MS Office) and then delete the bakup of the original folder ("Adobe.bak").
It takes 2-3 minutes. I did it with Microsoft Office and Adobe and managed to free over 2GB on my C drive. You will still see the Adobe folders on C, but it is just a dynamic link.
