Hello,

It is not easy to solve your issue, i do not have a lot of info.

There are different flags that you can use with the fopen command in C.

One of them determines if you read the file binairy or in a sort of interpreted text mode.

Are you reading the files in binairy mode ? (fopen with flags "rb+" and "wb+"), if not, interpretation CR/LF can cause deformation of data.

Best Regards,

Johi.
