This is due to FAT32 limitation on your USB Stick. Files larger than 4GB can NOT be stored on a FAT32 volume. Formatting the flash drive as exFAT or NTFS will resolve this issue.
Formatting a drive in exFAT
1. Double-click on My Computer.
2. Right-click on the flash drive or memory card, then select Format.
3. In the File System list, click exFAT.
4. Click Start.
5. Click OK to start formatting.
