making directories from another drive appear in root of first drive

My "media" collection of photos and music occupies a total of 1.1 TB. On my desktop system, no problem, with a 4 TB HDD. On my laptop, where I like to duplicate this collection for my business trips, I can devote only 200 GB on the laptop's internal SSD. I have to keep the rest on a 1 TB external USB HDD. As a result, two drive letters, E: and I:.

Is there any way to make all the root directories on the external HDD appear as root directories on the SSD, so I am dealing with only one drive letter, as on my desktop?

Both systems are running Win 10 Pro 64, fully updated and patched.

A few ways to do it but may be a problem with root but a folder no problem if you make a folder music then from a cmd prompt type subst e: c:\music

Thanks, but I'm trying to eliminate drive letters.

Let me be more specific in what I'm looking for. In my E: drive on my desktop, the major top-level folders are:


\Lightroom
\PhotosToImport
\PhotosRejected
\iTunes
\Books

For space reasons, I can fit only the \Lightroom directory on the laptop's SDD. All the other directories have to go on that 1 TB external HDD. However, I am looking for a way that all those other directories appear to be in the laptop's E: drive when the external drive is connected.

Right now, having to remember where a particular directory is causes a lot of confusion.

Look at mklink for creating Junction points and hard links. I think that will do what you want.
