Unable to copy files more than 4GB to USB drive

This is a general problem one will face when they use external USB storage. Most of the USB mass storage vendors, packs their disks with FAT32 formatting (not sure why). This limits us from copying a file which is more than 4GB. It’s a limitation with FAT32 partition. Another thing I noticed is, we cannot copy more than 100GB into a FAT32 formatted USB drive though the drive capacity is more than 100GB.

So, if your USB storage disk of any size more than 100GB, I prefer formatting it with NTFS before you really use it. If you already have some data in it, and cannot really copy it to somewhere for formatting, you can give a try with “covert” command which coverts your USB drive to NTFS from FAT32 without losing data. Try at your own risk, I cannot guarantee. Chose this utility if you really don’t care or don’t have a place to back up your data

Happy Learning,
