Users of SyncBackPro Version 6.5.48.0 and later can change the MIME Content-type for files that are uploaded to a Cloud Storage Service by using a custom MIME.TXT file.

Create a text file called mime.txt in the folder where the SyncBackPro executable is. By default, this location is at

32-bit: C:\Program Files (x86)\2BrightSparks\SyncBackPro

64-bit: C:\Program Files\2BrightSparks\SyncBackPro

However, it may differ if you chose a different installation path during setup.

You can open mime.txt to edit and specify the extension and what mime type it should be. Specify one extension/mime per line. For example:

txt=text/plain
asf=video/x-ms-asf
webm=video/webm

Please note that it is not necessary to put a period before the extension (example - txt instead of .txt), but it wouldn't matter either if you place the period before such extensions.
