A Fresh Look at File Sharing Services It is becoming increasingly difficult to send and share large files. A relatively simple new prospect submission to a carrier can grow to 10MB in size quickly. File sharing (synchronization) services allow you to create a virtual folder to store files and then allow remote access to those files from any Web browser. These services also allow stored files to be synchronized between computers, tablets, or smart phones. This helps to ensure that files you are working on are instantly accessible to other people you have allowed access.
