Folder name containing ".." on ExFAT: How to rename it? Invisible to ls/mv/Finder but visible to tar/bash
You can rename it by using the inode.
First, get the inode of the file (I have a file named test for this example):
ls -li 
8624175 -rw-r--r--   1 allan  staff     0B Jul 15 12:05 test

You will need the very first number in the line - 8624175
Now, using the find command, rename the file to something else:
find . -inum 8624175 -maxdepth 1 -exec {} mv newname.txt \;
