Any problem using both local and portable XY the same time ?

[tag.mania]

Hello !
I use my hard disk in a very strict way many years, so I always have C: and D: where on C: I have programs and on D: I have only data.
It's not so rare for me to restore (using norton ghost) the whole C: many times a day (usual when a virus is possible coming via internet) so it's crusial to have always my data on D: and nothing on C:
So I installed normally (not portable) XYplorer on C: and changed the startup.ini to "look" at D:\XY\ where I copied all XYplorer data.
I also made a new ghost (partition image) of C: in order for the XYplorer to be permantly into my installation after any future partition restore.
After setting some thousands file tags I remembered that a new feature called "portable tags" had already included so going to check I saw that it was deactivated (I can't select or deselect) !
I read that XYplorer had to be at the same partition from the beggining ..... I say ok, I'll resolve that and so I took the xyplorer_full_noinstall.rar and just unzipped into D:\XY_prog\
After that, I took the startup.ini (because I didn't find any at the portable edition) and copied to the D:\XY_prog\ so voila !
The portable edition on D: "looks" exactly the same XYplorer data as the normal version on C: !!!
So where is the big deal ?!
The point is that when I open the XYplorer on C: the checkbox for "portable tags" is still deactivated but at the same time the XYplorer on D: (which looks the same data) has that checkbox ACTIVATED !!
So finally I have a bad feeling that a great disaster may waiting for me if still using both XYplorer (it's easy to say "ok I'll use only the portable version on D: but what's gonna happen by mistake if use the local ?

Is there actually a problem or it's just my fear ?

PS : also, is this finally the best way for someone to overcome the constraint for having the program in the same partition with the data after a long long using of local version though he has the data at another place ? (I mean : did I find a solution or is a dangerous trick )

1. "portable tags" is meant for USB sticks that you carry around to another system where they may receive a different drive letter.
2. no disaster can happen when you backup tag.dat once in a while Backup is a traditional and time-proven anti-disaster weapon. I know only one better weapon: double backup.
3. When XYplorer.exe is on the same drive as the app data folder then the checkbox is activated. This is what you see. No surprise and no problem.
4. I'm currently not sure what will happen if your local installation tries to read the portably stored tags; I guess it will fail. I was never meant to do this after all.
