I am using a gtar command that should create the file of 10 GB in pendrive. I researched on it little bit and got to know that FAT 32 file system supports file of size 4gb max. How can I put check in middle of running gtar command that creates multiple files by splitting based on file size less than 4gb. 

Gtar should be able to detect if file it creating is exceeding 4 GB size and then it should stop creating that file and continue creating the other one. 

I know that we can make 10 GB file at one location and split that static file, but we do not want this.
