Use the long path tool for managing files that have very long filename
If you are facing problems in managing files in FAR or windows explorer and getting error messages saying - The file is in use by another program or user, then it is most probably a problem emanating from long path name of the file. Because of this every time you will try to delete, rename, remove or copy files, it will throw up a message saying - The file is in use by another program or user.
If the file that you are trying to manage is open then you have to close it and then try to perform the command. If the file does not budge still then, then you should be sure that the problem is due to long path name of the file. However, you can check with a virus scan also to be doubly sure about the root cause.
