Moving original files when you use your own folder structure

Question

I currently maintain my own folder structure (on the HDD) for Aperture to read files from (rather than allow it to create its own complicated structure). Based on what i have seen so far, I understand that Aperture links its project with the HDD folder from where you import images.
In an instance, where I moved my file from the HDD folder structure, the image still appears in Aperture, but with a yellow question mark, and it does not allow me to edit it. Here I am assuming that since i moved the file from its HDD folder, Aperture is no longer able to locate it. Hence, I have the following queries about moving/ deleting files from my HDD:
Q1: If I want to move a file from one HDD folder to another, how do I do so without losing its link in Aperture
Q2: How do I completely delete a file from my HDD using Aperture? Assume here that I have imported it into Aperture but haven't made any changes to it, which means that I have only one version, the master version. Currently, when I delete it in Aperture using 'Delete version', I notice that the file still exists in the HDD folder). Is it that the only way to delete a file is to do so first from Aperture and then use Finder to delete it from the HDD folder? If not, whats the best way.
Q3: There is another scenario for Q2 - If I have made changes to a file after importing it in Aperture, there are now two versions, master version and edited version. If I want to delete both these files, whats the best way to do so.

Answer 1

OK let's take a step back here.  In your previous post you wrote asking how to move a file from one folder on your HD to another so that Aperture wouldn't loose track of it. And for that we answered to use File->Relocate Masters. The last two questions concerned deleting images from both Aperture and the HD. And we covered that.
Now you write:
f i want to move my master and version files from one project to another (and the corresponding master files too), i should first move the master files using File> Relocate master and then drag-drop the versions from within Aperture. (I usually maintain similar names for my HDD folders and corresponding projects in Aperture, hence if i move the master, then it makes sense to move the versions too).
Now you're bringing in  moving images in Aperture from one project to another.  What you are saying is correct but bear in mind:
The library structure inside Aperture is totally independent of the file structure you use to store referenced masters on the HD outside of Aperture.
Now It is possible to have one mimic the other as you seem to be doing but for all intents and purposes Aperture doesn't care at all how the external file structure appears as long as Aperture knows were the masters are.
So if you want to move masters INSIDE of Aperture from one project to another you can simply drag the visible image from the source project to the destination project. All versions will come along, versions are coupled to their masters and as such can't be moved independently. Any versions in Albums will continue to point to the master they came from.
Now if you want to move the master files EXTERNAL to Aperture you need to use the File->Relocate Master command so that Aperture will know were the files are.
Note: there is another command File->Locate Referenced Files that is used to connect Aperture to its referenced masters if the connection between the two is somehow broken. As for example what would happen if you moved the referenced masters using the finder rather then the Aperture command.
So you should be good to go, just remember that the two structures, Aperture library and referenced files, are independent and don't really need to be kept in sync. And by doing this you're  making extra work for yourself that isn't really necessary.
