Maybe you need **white** filter to see

files

• see_me.txt

solution

At first glance the file looks empty but taking a closer look at it will reveal that there are some bytes.

~$ xxd see_me.txt | head -n 5
00000000: 2020 2009 0920 2020 0909 0a09 0a20 2020     ..   .....   
00000010: 2020 0909 0909 2020 090a 090a 2020 2020    ....  ....    
00000020: 2009 0920 2020 0920 0a09 0a20 2020 2020   ..   . ...     
00000030: 0909 2020 0920 090a 090a 2020 2020 2009  ..  . ....     .
00000040: 0909 2020 0920 0a09 0a20 2020 2020 0920  ..  . ...     . 

Now the hint suggests some white filter. There are only spaces, tabs and newline characters in the given file. This hints that the given file is a whitespace text.

Using this tool you can get the flag.
