Inconsistency while using filters with LoadDirectoryFilesEx

[melikuomer]

While trying to load my assets I wanted it to scan sub directories as well. So I used LoadDirectoryFilesEx
I checked the code and found following filters.

raylib/src/rcore.c

Lines 274 to 282 in 7c48fa9

	#ifndef FILE_FILTER_TAG_ALL
	#define FILE_FILTER_TAG_ALL "*.*" // Filter to include all file types and directories on directory scan
	#endif // NOTE: Used in ScanDirectoryFiles(), LoadDirectoryFilesEx() and GetDirectoryFileCountEx()
	#ifndef FILE_FILTER_TAG_FILE_ONLY
	#define FILE_FILTER_TAG_FILE_ONLY "FILES*" // Filter to include all file types on directory scan
	#endif // NOTE: Used in ScanDirectoryFiles(), LoadDirectoryFilesEx() and GetDirectoryFileCountEx()
	#ifndef FILE_FILTER_TAG_DIR_ONLY
	#define FILE_FILTER_TAG_DIR_ONLY "DIR*" // Filter to include directories on directory scan
	#endif // NOTE: Used in ScanDirectoryFiles(), LoadDirectoryFilesEx() and GetDirectoryFileCountEx()

But when I use *.* I got no results. I explored a bit more and got really confused.
I feel like this is a bug. It would be great if anyone could explain me why this works like this.

#include <raylib.h>
#include <stdio.h>

void LoadAndPrintFiles(const char* filter){
  FilePathList filteredList = LoadDirectoryFilesEx("./assets", filter, true);
  printf("Filter: %-15s | Count: %u\n", filter, filteredList.count);
  UnloadDirectoryFiles(filteredList);
}

int main() {
  SetTraceLogLevel(LOG_NONE);

  LoadAndPrintFiles(NULL);
  LoadAndPrintFiles("");
  LoadAndPrintFiles("*.*");
  LoadAndPrintFiles("DIR*");
  LoadAndPrintFiles("FILES*");
  LoadAndPrintFiles(".png;");
  LoadAndPrintFiles(".png;.txt;");
  LoadAndPrintFiles(".png;.txt;");
  LoadAndPrintFiles(".png;.txt;DIR;");
  LoadAndPrintFiles(".png;.txt;*.*;");
  LoadAndPrintFiles(".png;.txt;FILES*;");
  //--------------------------------------------------------------------------------------

  return 0;
}

Filter: (null)          | Count: 5
Filter:                 | Count: 0
Filter: *.*             | Count: 0
Filter: DIR*            | Count: 2
Filter: FILES*          | Count: 0
Filter: .png;           | Count: 3
Filter: .png;.txt;      | Count: 5
Filter: .png;.txt;      | Count: 5
Filter: .png;.txt;DIR;  | Count: 7
Filter: .png;.txt;*.*;  | Count: 5
Filter: .png;.txt;FILES*; | Count: 5

and directory structure is the following

PS D:\Projects\Game\FirstTake> lsd assets --tree
 assets
├──  empty
├──  mydir
│   ├──  nestedfile.txt
│   ├──  test.png
│   └──  woah.png
├──  ok.png
└──  test.txt

And this is how i compile and run the program

clang test.c -target x86_64-pc-windows-gnu `
-I.\external\raylib-5.5_win64_mingw-w64\include `
-L.\external\raylib-5.5_win64_mingw-w64\lib `
-lraylib -lopengl32 -lgdi32 -lwinmm -o main.exe && .\main.exe

(Sorry if this is a badly authored discussion. I would love to improve on it if you provide feedback)

@melikuomer thanks for reporting, that function was reviewed recently so it can have some issues. I'm creating an issue from this discussion for further review.
