I was not saying the links are defective, but the arrangement seems defective.
I may have misunderstood you.
It is possible to move a sequence of folder from C:\Music\1\2\3\4 to D:\C\Music\1\2\3\4
and to use a reparse point so that it looks as if they are still present and accessible from C:
You could have more music at E:\D\a\b\c
Is it not possible to add a reparse point at D:\C\Music\1\2\3\4 to point at the music on E:
so that looking at the contents of C:\ it would appear to hold C:\Music\1\2\3\4\a\b\c.
I also envisage using a reparse point to result in the appearance of C:\Music\1\2\3\4\2\3\4
but if the reparse point placed at D:\C\Music\1\2\3\4 was to designate 3 folders back, i.e. D:\C\Music\1\2\3\4,
then the recursive view from C: would be
That is the situation I understood you to have,
and it seemed to me that there is no reason to have a recursive arrangement,
If you have played the music which is in C:\Music\1\2\3, will it sound different from C:\Music\1\2\3\4\2\3 ?
That is why I thought it a defective arrangement - I see no merit.
When I first learnt about reparse points I thought about the things I could do with them.
I thought about putting a reparse point at the end of C:\1\2\3\4 which linked back to C:\1,
so that I had the never ending sequence 1\2\3\4\1\2\3\4\1\2\3\4
My experience with Win XP Home edition is that it starts up much slower if the external drive is switched on, and the LEDS indicate it is being read from before I am allowed to logon.
I decided that the Operating system likes to know everything that is on the disks before it lets me log in,
and if it had the opportunity to recurse through an infinite loop it would never end.
I chose not to experiment because I anticipated the need to dust of my Acronis Boot CD to restore my system.
Windows is more clever than I realised if it will recognise and cleanly exit from an infinite loop.
Windows normally surprises me in the other direction ! !
For myself I would expect an A.V. scan to travel through the reparse points and detect any viruses that may be present in the applications that have been repositioned.
I tested before I implemented, and was satisfied that :-
PerfectDisk would still defrag drive C:\ and not try to walk through the reparse point and also work on the next partition;
Acronis would exclude from its image of C:\ anything that was actually moved to the next partition.
Everything else I tested was fooled by the reparse point into thinking those moved things were still on C:\
I did notice two anomalies with Windows Explorer.
With Program Files selected in the left hand tree I could click select all and all the application folders on the right were selected, and a right click told me
Size 1.36 GB (1,462,392,410 bytes)
When I deselected the Hewlett Packard folder a right click on the remaining group of folders still gave me
Size 1.36 GB (1,462,392,410 bytes)
Windows Explorer obviously did not look inside the HP folder when measuring the size of the group,
but when I selected only the HP folder a right click showed it held
Size 186 MB (195,362,179 bytes) - so that did not appear as part of the total - not what I expected but I can see why they do it that way.
There is a strange difference in the Size on Disk of the HP folder.
Regardless of whether Program Files is in the left hand tree and I have selected the HP folder,
or alternatively clicked through the reparse point so the contents are on the right and all selected,
Size on Disc 149 MB (156,483,817 bytes)
But the real location on Partition D:\ I am told
Size on Disc 192 MB (201,392,128 bytes)
All three sets of properties show the same quantities of files, folders, and bytes holding data,
but the drive D:\ reality of Size on Disc is not seen by two of the measurements.
I suspect Windows Explorer gets a bit confused when it is peeking through a reparse point.
Now that is the sort of foolishness I expect from Windows ! !
