Trying to write 4Gb video file onto flash drive with 10Gb free and it says
How can it be?
Flash drive is writable. Smaller files can be created / written.
That drive is formatted as FAT32. FAT32 doesn't support file sizes over 4GB.
Your Flash drive have currently the File system as FAT32. You need to have the file system as NTFS so you can be able to copy files more than 4 Gb size.
To do this, you have two solutions :
1 - Convert it from FAT32 to NTFS by doing the following:
Go to cmd and type the following :
convert G: /FS:NTFS
G: (G is your flash drive letter as your picture shows)
(You will not loose any existing data on it when converting)
2 - Format your Flash Drive and choose NTFS as File System
(You will loose all the data on it)
