Out of sync with receive-only instance

Hi, a folder on two PCs is in sync. On both PCs the folder is send & receive. Now I want a “backup” on the phone that is receive-only. This backup is not modified by any program but a file run out of sync. If both PCs are synced, it should not be possible that a read-only instance runs out of sync?

hello

yes its possible. eg : 2 files with same name on your PC ( case sensitive … test.txt and TEST.txt ) but cannot both be copied to phone ( case insensitive ).

Use a file explorer to check if file is there or not on your phone.
