FBackup: There is not enough space on the disk error

FBackup did not backup my files

My backup is working fine with FBackup except it won't backup my Outlook .pst file. This is the error I receive: Skipping file..., Destination error (code 112). There is not enough space on the disk.
But the problem is that my destination drive has 95 GB available. The .pst file that is trying to copy is 4.52 GB. It will backup to the destination drive only 3.99 GB. Is there a limit on the size of an individual file that it will copy? Any help would be appreciated. Thanks.

- Question from

If you meet the error it probably because your destination drive is a USB drive formatted with FAT32, please format USB drive to NTFS to fix. However, there still a chance that you can’t fix the error even there is enough space and formated with NTFS.

Moreover, you might get the FBackup scheduler not working problem, and you can’t fix it. What should you do? It’s time to turn to FBackup alternative - AOMEI Backupper Standard for help.
