The sync folder should not be modified by anything other than MobileSheets. It's not designed to be used that way - if you want to use the cloud sync functionality, you have to let MobileSheets manage those files. This is because the database that is stored in the cloud folder does not match the database on the device - it maps all of the file paths to cloud file paths. If you modify these folders or the files underneath them, the database will then no longer be pointing to valid file paths. So it won't matter if you do update the hashcodes file (which would be difficult), because the database itself has relative file paths that you've modified. There is also the matter of all of the last modified timestamps which would no longer be correct if you are manually modifying files under the sync folder (in addition to the hashes that are calculated).

I think you should keep your sync folder separate from the OneDrive folder you are synchronizing to your Windows device. Then when you are ready to sync to Android or iOS, just sync one of the Windows devices to the sync folder to push the latest changes, and then you can pull those changes on Android and iOS. The push shouldn't take long as it will only process the delta from the last push, and the same is true when pulling down the changes.
