fix: correctly retrieve the fileSize on 32 bits OS

adoussot · adoussot · commit cec93d6b8ad4 · 2018-06-21T14:20:53.000+02:00
"size_t" size depends on the OS. On 32-bit system it can only hold a 32
bits variable = 4 294 967 296, which is not enough to store a big file
size (e.g: 14Go). We should use a 64-bits variable
