Zend OptimizerTM User Guide
files are system-independent, certain tools for transferring files from Windows to Unix and vice-versa change the contents of the files so that they appear to be text files. To prevent this from happening, always use "binary transfer mode" when transferring encoded files with file transfer tools or ensure integrity of the files by using a package such as: zip or tar.gz.
For additional information, see the “Avoiding Incompatibilities” section in the Zend Guard User Guide.
