Dear abedhaddad,
Sorry for late reply and thank you for giving us an opportunity to improve our software.
We studied the issue that you reported and we noticed that the reflectance spectrum was not available when the instrument was disconnected. We enabled to view the spectrum/reflectance data after loading aging files regardless if the instrument is connected. Here is the link to download the MFT upgrade:
MFT 3.0 upgrade.
The reflectance files (.rfc) are exported only for external use . This type of files cannot be imported. However, after aging file import, all the collected data are restored and the spectrum/reflectance may be viewed.
