Hi! I can confirm that this is a FileZilla issue and yes, changing the transfer type to binary corrects this. -FS

Hi all! Just thought I'd offer a resolution for an issue I was observing on Mac with the very convenient PKHeX.app (17/03/08) - Thank you @jasenyoface! I like many use an FTP (FTPD + FileZilla) to transfer smaller files like screen captures and saves to-and-fro without un-mounting my SD - I also don't have an SD reader for my Mac so this is most convenient. I've seen multiple posts about the dreaded "unsupported file" issue and I also ran into this. It seems that FileZilla's default settings are to blame. The default file transfer type is set to 'Auto' and for whatever reason reduces the file size by and arbitrary byte (441,855 vs. 441,856 bytes). Correcting this can be accomplished by changing the Default transfer type from 'Auto' to 'Binary' in File Types under the Transfers section in FileZillas Settings - FileZilla > Settings > Transfers > File Types > Default transfer type: > Binary (Image below). Thank you for the wonderful software and community! -FS
