Syncing files between multiple computers in different locations has been a difficult task. Syncing software will often end up creating duplicates of files because it can't determine which file should take precedence over the others. It also might not delete files in other locations if you delete them in one place, and therefore it isn't "true sync." This is why the concept of the "cloud" took over, and it has solved many of these file dilemmas.
Microsoft's OneDrive is a free cloud option for Windows users, and it comes with your Microsoft account. Files stored in OneDrive can be accessed from anywhere, and it doesn't cause the mess of dupliate files that syncing creates. This is because your files are stored in one central location (OneDrive), and they're not stored on each individual computer. This means you're just working on one file that's stored in the cloud.
You can move files from your computer into OneDrive for your own use, or save your work to OneDrive automatically. In fact, on most PCs, OneDrive is the recommended location that appears when saving Microsoft Office files. Devices that have cameras such as phones or tablets can also be set to automatically upload photos to OneDrive for backup.
Once your files are in OneDrive, you can retrieve them from any device through a browser, or by using one of the mobile apps for Android, iOS, or Windows Phone. If you know you're going somewhere without internet access, you can make files accessible offline on your PC. This can be done on an individual file basis, or you can choose to make all files accessible offline in the OneDrive app or right from File Explorer.
Microsoft gives you 15 GB of free OneDrive space, with the option to purchase more if you need it. To find out more about OneDrive and sign up for a free account, go to onedrive.live.com..
