I need to create, read and modify files using filex. Such files have names that uses cyrillic characters set (they must be codified using unicode 16 bit). It is possible to manage such files? 

Thanks

Hello ​@Gengiz 

Yes, FileX can handle filenames with Cyrillic characters, provided you use the Unicode filename APIs and the filesystem is configured with Long File Name (LFN) support. In practice, filenames must be passed as 16-bit Unicode strings to the corresponding FileX Unicode services for file or directory creation/opening. Standard read/write operations on the file content remain unchanged once the file is opened. So, if LFN/Unicode support is enabled in the FileX configuration, creating, reading, and modifying files whose names contain Cyrillic characters is supported.
