Win8.1 enhances the priority of SkyDrive cloud storage, and files are first saved to SkyDrive under Default settings. However, if the network environment is not too good, some large files in the download will consume more time, if offline, you will see the file is not available hints, sometimes very delayed. There is no good solution.
"Ideas for solving problems"
Under Windows 8.1 defaults, all files in the desktop version SkyDrive are online available, and the file is downloaded to the local area only after a file has been opened. We can break through this point to solve.
"How To solve problems"
into the Windows 8.1 desktop environment, open File Explorer, select SkyDrive under the left navigation tree, select files or folders that you want to use frequently in the right pane, right-click, and choose Offline Available from the right-click menu, so that these files are available if there is no network. This, of course, takes up hard disk space.
If you have enough hard disk space, you can also consider setting all the files to be available offline: Open SkyDrive from the Start screen, select Settings from the Super toolbar, go to the Settings screen, select options, and in the right pane, set offline access all files to Enabled. If you right-click the SkyDrive folder or file in your desktop environment, the right-click menu increases the option to only be available online.
