Even though Microsoft's OneDrive rivals Dropbox in the cloud storage industry, the two companies have recently partnered on the Office productivity suite, offering mutual customers a choice of cloud storage options they want to save on. Still that hasn't stopped Microsoft from trying to lure Dropbox users to its own service.
Recently, the software giant has started offering 100GB of free OneDrive storage to Dropbox users for one year. In order to get the storage, you will have to verify that you are a Dropbox user by allowing a document to be uploading to your Dropbox account. Just like Dropbox, OneDrive is a cross platform cloud storage solution which allows users to sync their files between PCs, Phones, Tablets and the Cloud.
