PNG File Encoding and Reading

Extending the correct answer from SigTerm, here is some background of why you got the effect you did for opening a PNG file in text mode:

The PNG format explains its 8-byte file header as follows:

The first eight bytes of a PNG file always contain the following values:

   (decimal)              137  80  78  71  13  10  26  10
   (hexadecimal)           89  50  4e  47  0d  0a  1a  0a
 (ASCII C notation) \211 P N G \r \n \032 \n

Linux Commands - Count Files in directory 
$ find . -type f | wc -l

Explanation: find . -type f finds all files ( -type f ) in this ( . ) directory and in all sub directories, the filenames are then printed to standard out one per line.

This is then piped | into wc (word count) the -l option tells wc to only count lines of its input.

Together they count all your files.
