lets say you search for a player file, than you use some pattern for like like PlayerName.txt

pawn Код:

new name[MAX_PLAYER_NAME];
GetPlayerName(playerid, name, MAX_PLAYER_NAME);
strcat(name, ".txt", MAX_PLAYER_NAME);
if(fexist(name)) {}

or you got some maps and dont know if the map exist

pawn Код:

new name[16];
format(name, sizeof name, "Map_%d.txt", mapid);
if(fexist(name)) {}

or just tell me why you need to search in a folder for some random files?

If you want to create a command which list all registered players as example
Than you only need to create an extra file which stores all names
