For those folks who work on both Windows and Mac, and who want to share Desktop and Documents files easily between the two systems, you can use the iCloud application on Windows. When installed, you can click on the iCloud icon on the taskbar and then “Open iCloud Drive”. File Explorer will then open up to your iCloud folder. Never attempt to sync files outside of the home folder such as 'Applications', 'System', or 'Library' between two Macs. Problems can arise if Applications, or System files are synced that can easily result in application failure or a corrupt OS. In syncing two Macs, the focus needs to be on the home folder and the data files stored therein. Hello, today I'll be showing you how to share files between Macs. ⚡Twitter (I do give aways!)https://twitter.com/CarsonNotFound⚡Instagram:https://www.instagr.
Most people with multiple Macs need to synchronize more data than .Mac Sync can handle-such as word processing documents, spreadsheets, PDF files, e-mail messages, photos, videos, and music. If you’re a .Mac member (soon to be MobileMe), one approach is to put files you want to sync on your iDisk. Then open the Mac preference pane on each Mac you want to sync, go to the iDisk tab, and make sure that iDisk Sync is set to On (if it isn’t, click on the Start button). This creates a local copy of everything on your iDisk, which you can access even when you’re offline. As long as Update is set to Automatically, whenever you save a file to your iDisk, OS X uploads it to Apple’s servers and downloads it to any other Mac you’ve set up in the same way.
However, syncing one or more folders on your iDisk or using a service like SugarSync may not meet all your needs, especially if you have huge volumes of data or if you want the speed of direct Mac-to-Mac transfers (instead of waiting for an upload followed by a download). In such cases, a better bet is to use a file-synchronization utility. (For such a utility to work, your computers need to see each other over a network; see “Set Up File Sharing” for details.)

How Sync Utilities Work Almost all synchronization utilities have certain features in common. You specify two locations you want to synchronize-say, a folder on your laptop and the corresponding folder on your desktop Mac. Then you choose the direction of the synchronization: you might specify that files copy from the desktop to the laptop only, from the laptop to the desktop only, or in both directions (thus making sure both locations end up with identical contents). You may also have to decide what action the software should take when both locations contain a file with the same name but different contents-choices include overwriting the older file with the newer one, renaming one of the files and keeping both, and pausing to let you decide what to do on a case-by-case basis.
After you set up your preferences and activate a sync, the software scans the files in both locations and copies just the ones that aren’t already the same in both places. Depending on how you set things up, the software may also delete files from one side that were deleted on the other, in order to make the two locations identical. Some synchronization software can perform syncs automatically on a schedule or when other trigger events occur, such as mounting a network volume. This can be useful, for example, if you want to synchronize your laptop with your desktop Mac every time you come home from a business trip and connect to your local network.
Choose Which Files to Sync If both Macs have suitably large hard drives and if you do similar work on each, you might consider synchronizing your entire user folder (/Users/your user folder) between the two, as that folder likely contains all your personal files. Because your user folder includes, by default, all your music, photos, and e-mail, not to mention the information included in a .Mac sync (contacts, calendars, and so on), syncing the whole thing can eliminate the need to come up with a separate strategy for each kind of data.
However, syncing all your data in this way can be highly problematic-in fact, it can actually lead to data loss if you’ve used both computers between synchronization sessions: If you’ve changed database files (including those that Mail, Entourage, or iTunes uses), disk images (such as the ones that hold Windows installations for Parallels Desktop or VMware Fusion), or other similar files, one computer’s version of the file will overwrite the other’s, rather than specific data within the files being synchronized. Unless you know for sure that files will not change on either computer while the other is in use, it’s much safer to restrict synchronization to more-specific folders.
If you normally keep the documents you create in your Documents folder or in one of its subfolders, syncing the Documents folder between two Macs is a reasonable choice. However, you may want to be more selective. For example, let’s say you use your desktop Mac for page-layout work in Adobe InDesign and store those files in Documents, but you never use InDesign on your laptop. You can save time and disk space by excluding the folder(s) for desktop-publishing documents from syncs. Or if you use your laptop mainly to edit Microsoft Office documents related to a particular project, you might decide to synchronize only the folder(s) you store that data in.

File Syncing Tips For the most part, once you’ve selected the files you want to sync, getting the synchronization done is simply a matter of choosing a source, a destination, and the particular options in your synchronization utility, and then clicking on a Synchronize button. However, a few tips may help you to avoid potential pitfalls:

Don’t Sync Applications Many applications store essential components outside of the Applications folder (for example, in /Library/Application Support and other Library subfolders, not to mention preference files), and chances are good that you’ll miss some of those pieces when you try to sync applications. The result could be malfunctioning programs on one or all of your computers. For more reliable operation, install applications on each computer separately.
Test Syncs First Many sync utilities offer a test mode that lets you see what changes would be made during a sync, without actually copying any files. Checking out these sync scenarios ahead of time has saved me from losing files to user error more than once. For example, you can click on ChronoSync’s Trial Sync button instead of its Synchronize button, or you can go to FoldersSynchronizer X’s General preference pane and select Show Preview in the Before Sync section.
Delete with Caution When performing a bidirectional sync, as you most likely will when synchronizing two computers that are both used actively, sync utilities let you specify whether to delete files that have been removed from the other side. This may be what you want, but it could also result in the loss of important data if you have a preference set incorrectly or if you delete a file by mistake. At least for the first few runs, until you’re comfortable with the way your synchronization works, choose a setting that moves deleted files to another folder or asks for your approval before deleting them.
Sync Selectively In some situations, you won’t want to synchronize all your important files between both of your Macs. For example, you may not need many of the files in your desktop Mac’s Downloads folder to be transferred to your laptop-especially if the laptop is short on disk space.
