4Sync is a tool that lets you sync virtually every device you own so you can access your files anywhere. The web app gives you access to your files from a manager on 4Sync's website.
4Sync is similar to other file storage services like Dropbox and iCloud in that it gives you a way to store files and access them across multiple devices. This includes on a Windows PC, Mac or mobile devices such as Android and iPhone, among others.
Share photos, music, videos and other files with 4Sync. Setting up an account comes with 10GB of free storage space. To access your online manager, you're going to need to register on either a desktop or mobile app, which can be a bit of a pain if you just want to access your files via your web browser.
During the registration process through 4Sync's desktop application, you'll be asked to create an account by providing an email address and password. Your email address acts as your username to access this web app version of 4Sync. If you want an additional 5GB of free space, you'll need to verify the email address you used to register in the first place. On the bottom left of your web account's main screen, simply click the blue button with the white plus sign that says "Get 5GB free." A verification link will be sent to the email address you provided. It's a little tedious, but definitely worth it for fifty percent more space to make use of.
4Sync's browser based interface is nothing special in terms of looks, but it is functional and easy to use. You can either drag and drop files into the manager or else upload them directly.
Syncing occurs immediately across devices that have an internet connection as well as a 4Sync application installed. 4Sync also makes sharing certain files with friends easy by providing you with a shareable link whenever you want to make files public or selectively viewable to others.
If you're looking for an alternative to Dropbox or iCloud to store files and sync across devices, 4Sync is a great alternative.
