How can I obtain a file s size in C? I opened with an application written in C. I would like to know the size, because I want to put the content of the loaded file into a string, which I alloc using malloc(). Just writing malloc(10000*sizeof(char)

You can use the fseek and ftell functions:

FILE* f = fopen("try.txt","rb");
fseek(f, 0, SEEK_END);
printf("size of the file is %ld", ftell(f));
