Are you kindly considering adding a feature to skip / ignore certain paths (directories, files) stored on local machine from syncing? Some examples of situations where inability to exclude files from backup causes undesired issues: 1) There are programs which store temporary files among synced folders. These temporary files frequently change and are deleted on program exit, which results into frequent unnecessary synchronization and deletion of files in cloud, therefore waste of computing resources and bandwidth. 2) Specific program creates empty file "running" to indicate it's in running state. Box Sync does not sync empty file but warns user each time such program starts that it's unable to sync "running" file. In some cases I am getting multiple notification each hour. 3) Some games tend to store their data into "My Documents" folder. Those data do not need to be uploaded to cloud or to be accessible from other devices. Also, when the game is running, their frequent updates results into waste of computing power and bandwith again. 4) Some large files unable to be synced could be skipped, resulting into quicker sync time. Users should be able to choose what to sync and what not, and the possibility to exclude files or folders from syncing would greatly improve Box Sync experience!
