This is mostly wrong. Most of them are just crap, dunno how Windows calculates them.
@OP, you can go to
X:/Program files or
X:/Program files(x86) where X is the drive letter on which the program is installed, then right click the required program subfolder and see its properties to check the size. But this is still not the exact size because program components are stored at other locations as well.
Warning
Most programs will NOT work just by copying the program subfolder as already said by VistaKing since they use registry keys in order to work
I was not offended by your post. I did not interpret your post as saying that I had posted wrong info. I interpreted your post as saying that Microsoft delivers poor estimates via that screen. That said, be careful whenever you use the word
wrong in a post. According to some studies, most Americans are strangely non confrontational. This means that they may just leave a forum rather than tell you that you offended them.
Even if you had directly called me wrong - saying that I posted a totally wrong answer. I'm a big boy; I can handle it. I would hope that I would simply discuss the issue via further post and remain friends.
I try to give the
benefit of the doubt to those for whom English might not be their first language. And
idioms must drive readers crazy. I find some posts by Brits and Aussies to be most educational. I make frequent use of my search engine accelerator.
I say all of that to say this. What follows is some of my thinking/labor that went into the tiny post that I made. I don't mean for the info below to sound as if I'm being defensive due to be offended (which I was not):
I intentionally used the word
maybe - which was meant to convey that the OP may find the desired info on that screen... and maybe not. I should have been clearer in my post. And since I've spoken about offending people. I'll make it clear that the term maybe was not meant in a condescending manner; but I can see how my short post could have been taken that way.
What my first post in this thread does not show is the labor/research that went into it.
I too had originally included a few words of warning about not moving program files to another location via the Windows (file) Explorer, but then I figured that it was presumptuous of me to assume that the OP (who used to words move and
transfer) did not already know how to transfer program to a new location. It can be done. I was not going to get into how to do so and the issues that this can cause later on. (Although the last sentence in the OP does seem to indicate a certain knowledge level.)
Before I made that post, I compared the size for Abobe Reader XI (125MB) as reported in the screenshot to the size reported by various folder properties from within the Windows (file) Explorer.
This folder...
"C:\Program Files (x86)\Adobe"
...indicates 115MB of space.
This folder...
"C:\Program Files (x86)\Common Files\Adobe"
...indicates another 7MB of space.
I'm not sure that I found all of the various Adobe folders sprinkled throughout the user's profiles; but adding up the ones that I located = ~2MB.
This came close to the 125MB, so I made that post.
I failed to include the size of this folder "C:\ProgramData\Adobe" (142MB) which is needed to run the app. This puts the info in that program and features window at less than 50% of the actual space occupied by the app. So, the info in my first tiny post was indeed crap.
Maybe the OP will find this much more verbose post of more use... or maybe not
