Hi Geoffrey Martin:
Thanks for posting.
Currently, FileMaker database sizes are limited only by remaining disk space, up to a maximum of 8 terabytes. A FileMaker database of 4.5 GB should be able to copy over onto a flash or external hard drive.
What is the processor speed and RAM on your Windows XP machine?
What folder is your database stored in?
What is the exact error message that you are getting?
Do you have any other non-filemaker files that are larger then 4.5GB? Could you try copying this file through Windows onto your external device? If large non-filemaker files get the same error, it could indicate a system or OS issue.
I would also suggest testing a different FileMaker database. In FileMaker, create a new database file. Under the file menu, go to manage and database. Under the fields tab, create a field called container, set to type container. Right click the container on your layout and choose either insert picture or file. Now select a large file, make sure store only a reference is unchecked, and click open to insert the file. Click the new record button from the status bar, and continue adding large files until you reach a database of 4.5 GB in size. Try copying this new file to your external device and see if the error occurs.
Check the File System of your system on your computer if its not NTFS (some early XP systems could be running FAT32) it may be limiting the file size.
You can check the the file system by right clicking and selecting properties on the drive.
I'm running the lastest update of Filemaker Pro Advanced 11 on a DELL AMD ATHLON DUAL CORE 2.3 Ghz with 3.25 Gb of memory. The OS is Windows XP Pro v2002 Service Pack 3, (XP Professional 5.1.2600). The USB stick's file system is FAT32 and the C drive is NTFS. The file is located in a folder on the desktop called LCATS.
Couldn't reformat the USB stick to NTFS so I found a link http://forums.hexus.net/corsair-care-hexus/145634-how-remove-file-size-limit-8gb-corsair-usb-stick.html. Told me how to do it and I've solved the problem. Thanks for steering me in the right direction. It is copying as we speak.
