If a file is modified on the server when you are offline, Offline Files in Windows Vista or Windows 7 will copy the whole file to your local cache during synchronization.Bitmap Differential Transfer works only for pre-existing files and not for files that were created while working offline.Because of this limitation, files modified with applications that do not modify the file in place will not work with Bitmap Differential Transfer.
By default, network folders in the "slow-link" mode will be synchronized with the server every 360 minutes with the start of the sync varying between 0 and 60 additional minutes.
Initially, only those blocks of data read by the client application are cached, producing a “sparse” file in the cache.
- Sparsely-cached files are available to the client only when the associated network share is connected (a.k.a. In order to make a sparse file available while offline, it must first be “filled” while online.
What are the settings in Windows 7: There are some settings with which you can play to ensure client are correctly synchronized before they leave the network (shutdown or logoff) : - Configure Background Sync : this policy applies only for Windows 7and Windows Server 2008 R2 (offlinefiles.admx) This is a machine-specific setting which applies to any user who logs onto the specified machine while this policy is in effect.
This policy is in effect when a network folder is determined, as specified by the "Configure slow-link mode" policy, to be in "slow-link" mode.
Filling of a sparse file ensures the complete file is in the cache.
