Not as straightforward as I would have liked but that's on me and not the app. I was stuck in a hard place when I could no longer install my paid for (no longer updated) app called SyncMe. It hasn't been available for a long time and I side loaded the last phone update. Well just updated my phone and the Android version wouldnt allow me to side load it so was stuck. This app works and takes care of my file/backup needs. Like stated above it it not as easy as my old app but I figured it out.

Useful app with recent issues. 4.x update removed the option to create FolderPairs that use the "legacy V1" engine (not documented in the changelog). Problem is, V2 engine doesn't have feature parity. In my case V2 gets stuck on syncing via SMB2 because there are root-owned ACL files in a hidden subdirectory that it can't read -- V1 I can tell "skip hidden files" and this is not a problem -- V2 doesn't have that option. Go back to app version 3.5x and can create V1 folderpair and works great...

Great app overall. It seems to get confused with the case of folders though. For example I have two folders that are identical other than the case of one of the letters (don't ask me why, suffice it to say that it isn't something I can fix) and the app seems to only recognize one of them. It's as though it thinks they are the same folder so it skips one of them after syncing the other. Other than that, it works great :)
