Overwrite - Yes - No File size is not the same, WHY ?

I don't remember since which version, when I upload a file , and the files have identical size, the overwrite window shows me a diference between the files, even if I uploaded the file now, and then try to upload it again ( without any changes to the file ) the filesize is diferent on the server .

How can this be done , I want to see the same size.

bellow is an exemple I see now for a file

Existing file
5.058 bytes

Replace with
5.157 bytes

but the files are identical, i did not change anything in the file I want to upload.

is this an ASCII text file? then line ends are automatically converted to the scheme used on the server, which reduces file size (CR/LF gets replaced by LF only).

Yes , probably this is why the file size changes , all the php files have diferent sizes but the images have the same size, only now I saw this .

10x for make me understand why the files are diferent

Keep up the good work
