How to sync in order to remove crash files?

I havent synced my ipad for years now and crash files have accumulated

my question is that: is there a way to sync my ipad to itunes without really syncing anything?

because i dont want to sync my photos, videos, songs to my pc(itunes)

is there a way for example syncing nothing to itunes but still be able to transfer those crash files in order to free up significant memory in my ipad?

thanks for the help
