I have a problem and I hope Linux has a solution.
I have an office in Florida and an office in Brussels. I have employees who travel to different parts of the world and need access to files.
I want a single file storage source that all employees can access easily over the internet. I understand the limitations of the speed of my internet connection. Will Linux provide me a solution to easily store and retrieve files from any location over the internet without using FTP software? Most employees use Windows but some use Mac.
Currently I have two aging Windows servers, 1 in Brussels and 1 in Florida and employees have a mapped drive to the server for file storage.

Linux has the ability to export shares as smb/cifs filesystems, which are seen by other hosts as if they are Windows shares. You can probably arrange it so your existing shares can be seamlessly replaced by a Linux server. This is all orchestrated by a system called 'samba'. You can find lots of information on samba on the web.
