Nothing to sync

[sfptd54]

Hello, I am a French user of FreeFileSync and for a few weeks, I have encountered a synchronization problem: despite many new or modified files, nothing happens when I start a synchronization; software's usual response: no files to sync. Sync between hard disk and portable disk. I confess that I do not understand what is happening, I specify that the software is up to date and that I work on Mac. Thank you for your lights. Cordially.

Check that the locations and filters are correct. You could start a new config and remake it, that may show where something was wrong
