Is it possible to stop Dropbox from syncing temp files and cache files that various applications create in the same folder as the file I want to sync? An example is MS Access, which has an accdb file that I want synced, but when I open that file on my PC desktop it temporarily creates a laccdb scratch file of the same file size or larger, and Dropbox syncs it. This file should not be used by any other device, and always resides alongside the accdb file. It's really tasking my other computers to constantly sync stuff they should not sync.
I have used the Selective Sync to exclude specific folders that include junk files but this only solves part of the problem. I have noticed on one of my Mac desktops that kernal_task is running amok when Dropbox is desperately syncing various large cache files (not even sure where they are - but pretty sure related to PC work in folders that I want to sync) and probably re-indexing. I do not want to sync cache files, temp files, scratch files.
To put my question another way, how to exclude specific file types / file extensions so that Dropbox ignores them even in my included folders?
