My $.02:

I use multiple runtimes, similar to the approach outlined by Believable 3D above.  When one gets ungainly (takes a while to open), I split it.  For example, I had a lot of DAZ characters (other than V4) in one runtime.  M3 items got to be a large volume, so I split that out into a separate M3 runtime.  How do I do that?  I maintain a separate but identical folder structure on a raid volume (in a folder called Poser Runtimes) and move each zip or exe file to the appropriate folder there after successful installation.  This way I always have the original content files organized according to my runtimes.  This also makes backup of the original zip/exe files easy.  I have an external USB drive which I hook up occasionally and copy everything over to.  Given the cost of an external 250 GB drive today, this is way more efficient than making DVD's.

When I want to split a runtime, I first split the folder with the content zip/exe files, then make the new runtime in my poser directory, delete all content from the old runtime (ie: Daz Characters) and then reinstall the content into the two folders ... Daz Characters and M3.  This process is greatly simplified if you have 3D Content Installer (by ahudson).  It will install all your files to a runtime at once (including Daz installers).  Really, this wouldn't be realistic without it.

Also, I tend to go into the pose folder and rename content which modifies a given product (like additional textures for clothes) so that the folder name begins with the original product name.  Makes it easier to find when looking for something.

Finally, if you have a lot of content, a poser specific browser is really helpful.  I use P3dO and find it does a nice job.  You can see your content, and locate where texture files are placed (useful when the program can't find something).  One thing to note, P3dO is not that useful for the renaming tip above.  You can do it, but the delay when renaming a folder is horrendous.  Better to do that in explorer.

Hope these tips help.
