Is there any limit or maximum to the amount of files we upload to MRSware?
There is no limit to the number of files, or the size of those files.
Your files in File Storage do count against your total storage usage. As such we recommend using File Share to store files that users need to access when outside the office, on the road, or that are worked on collaboratively (using the revision control system). What we don't generally recommend is uploading all of your files from your computer, or from a in-office network file storage device, as this will generally be lots of files that are infrequently (if ever) accessed.
