This link was in fact an NTFS reparse point. Using the “fsutil” command solved the problem. For example, in the case of an reparse point located at “C:\$Recycle.bin\S-1521\x\y\z\Documents”, you must:
1- Open the command prompt in administrator mode
2- go to the folder containing the link (for example “C:\$Recycle.bin\S-1521\x\y\z\”)
3- fsutil reparsepoint query (eg: “fsutil reparsepoint query Documents”)
4- fsutil reparsepoint delete (eg: “fsutil reparsepoint delete Documents”)
5- del (eg “del Documents”).
