RDB File Is Too Large For Destination File System

[jnpurdy]

In creating an external database, the file size is 4.07 GB.  The destination USB drive has 61GB available space.  When copying the file, I received the error that the file is too big.

I also received the same error when attempting to copy it to a 10GB drive that had 9.78GB free space.

Any suggestions?

Hi John,

This is a Windows file system limitation. Your USB stick is likely formatted using the FAT32 file system. This file system has a maximum single file size limit of 4GB. As this .RDB file is larger than 4GB, you will run into this error.

To work around this problem, format the USB drive using the NTFS file system which has a 16TB single file size limit.
