In general, Elite might fail to back up your files under the following three cases:
1.System files (including files in "My Documents", "My Music", "My Pictures" and other folders in the C Drive)
3.Files with over-long names or paths (this is an innate limitation of the Windows system)
If the aforementioned cases are detected by Elite, two types of warning messages will pop up as follows:
(1)If an illegal file type is detected before you started with the backup, the following message will pop up.
(2)If an illegal file type is detected halfway through the backup process, the following message will pop up.
