Windows 10: Unable to rename files and folders accessed via a junction

I am using an NTFS junction "C:\foobar" to access a folder that actually resides in "C:\Users\myid\Documents\foobar".

Trying to sketch this:
C:\foobar------------------------------+
|
V
C:\Users\myid\Documents\foobar\.....loooong paths here....

The reason for using such a junction is that the folder foobar contains a huge subtree of files (an eclipse workspace including the infamous .metadata directory) that tends to contain filenames and paths that are exceeding the old 255 character path length.
The file system doesn't have any issues with such long paths that but many tools do. Using the shorter path variant I have evaded all path-length related issues so far.

But yesterday I ran into a very strange issue:

For some reason I cannot rename folders and files anymore that I access using the shorter variant while I have absolutely no issue, renaming or otherwise manipulating the same directories and files when specifying the long variant, i.e.
issuing:
ren C:\Users\myid\Documents\foobar\xyz.abc xxx.abc
works perfectly OK, while
ren C:\foobar\xyz.abc xxx.abc
invariably yields a "The file is too large for the destination file system" error, regardless of whether I try to rename a folder or a file.

The odd thing is: this has worked before! For years! The error appeared yesterday and I have absolutely no clue what could have changed on my system to cause this.

For some odd reason file operations suddenly behave differently when accessing via the junction or when access using the full name.

I have verified that security settings/file permissions are the same via both paths ("Full access" for my user-id with all permissions ticked except "Special permissions"). I have rebooted the system, I ran chkdsk, etc.

Any ideas?

Unable to create a new folder or rename a folder

Hi Edver,

Thank you for posting in Microsoft community.

Sorry for the inconvenience caused to you. I'll certainly help you with this.

I would like to let you know that you may not be able to rename or add a new folder from Quick access. It will allow you to open the folders that are frequently used, recently viewed files or the files/folders that are added to
Quick access.

If you are unable to create or rename files/folders in other folders as well, then I would suggest you to run a SFC scan.

System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue. Kindly follow the below given steps:

• Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
• In Command prompt type sfc /scannow and press enter.
• Restart the computer.

Hope this will help you. Keep us posted with the status of the issue to assist you further.
