Why can you get all files and count them but not simply get the count? Where is the difference? Beware that File. So, there is an iterator that will loop through the entries here. Now, let's look to the counting mechanism. The Java 8 Files. I've been using Files. But I have a feeling that this is behind a few GC overhead exceptions I've encountered, because millions of file objects get instantiated and destroyed for each call. Still looking for a performant and memory-safe method I'd probably go with Varkhan's answer myself.

And I think you may want a -f if there are a lot of files in the directory, otherwise most of the time will be spent doing the default sorting.

Count files in directory and all subdirectories. When done properly, the terminal should return a single number indicating how many lines were counted and then return you to the prompt. You can also add the grep command to find a more exact count of the files you want to count, as shown below. In the example above, the command only counts files that begin with the letter "a". Linux users macOS users. Notice If hidden files are not shown, these files are not counted. Notice If any file or folder is highlighted, only the selected items are counted.
This isn't recursive — Kyle Bridenstine. The OP didn't ask for it to be recursive — Fandango Guillermo Pereira Guillermo Pereira 1, 10 10 silver badges 7 7 bronze badges. The editing queue is full so Please, do not use the builtins list, dir as a variable name or a placeholder!
This is where fnmatch comes very handy: import fnmatch print len fnmatch. This is much faster about half the time with my testing on a directory with 10, files if you know the pattern you're looking for, rather then testing each file with os.
Also significantly faster than glob. But not sure what's going on with underscores inside the sum function, could you please elaborate. This is completely recursive and probably the best answer here. This should be the most appropriate answer, to also count the files in any subfolders.. I am surprised that nobody mentioned os.
Works great with Python 3. This might be useful sometimes but it includes subdirectories in the count also — Brian Burns. Marcus Riemer 6, 7 7 gold badges 50 50 silver badges 68 68 bronze badges.

OP is not looking for recursive count — SilentGhost. Luke's code reformat. Here is a simple one-line command that I found useful: print int os. Bojan Tunguz Bojan Tunguz 41 2 2 bronze badges. Now a dialog box will come out and show you how many the specific type of files exist in the certain folder. Just close the dialog box.
