Transferring your photos, correspondence, contacts, and other important records to your new computer can be a hassle. Most of today's software services offer some kind of data transfer tool when you set up your new device, but these migration assistants are often unreliable. The Nerds On Call data transfer service is a great way to move your data from one device to another. PCmover Express* transfers data and configuration from computers running Windows* XP to computers running Windows* 8.1 or later.
If you want to access your data from anywhere, a cloud service is the best option. To get my data out of Chrome OS and be able to work with it elsewhere, I manually copy and paste from a Google Doc document into a plain text document on NextCloud (which synchronizes the files with Chrome OS devices through the Android application). You can also back up data to a computer when you have large volumes of multimedia files, such as photos, videos or music files. Once you install the application for the service you decide to use, it runs in the background and synchronizes your files with a remote server.
These services are usually free for a small amount of storage, and then a monthly subscription is charged as storage needs increase. If you don't want to buy an external hard drive, you can also move and store your files in the cloud using an Internet-based storage service, such as Microsoft OneDrive*, Google Drive* or Dropbox*. Cables typically come with software that automates the transfer of files when upgrading an old Windows* 10, 8.1, 8, 7, Vista, or XP computer to a newer computer.
