Sometimes we have been asked by our customers, DVD Presenter reported, “I receive the message ‘Your disk space is not enough’, though I still have huge amount of disk space actually”. How could this happen? Usually, our customers convert multiple very complex PPT presentations at one time. Thus, the converted file could be extremely large, sometimes one solide file could be few gigabytes(GB). In this condition, you might encounter the problem mentioned above.

It could be a little bit technical to explain the reason. Take it easy, it won’t be a big nut. Hard disc is used to store various files of our computer. To make sure Windows can recognise all files, hard disc is formated before intalling Windows. When format the hard disc, a certain file system is employed. Nowadays, for Windows users, we usually use two major file systems, one is NTFS, another is FAT32.  The first one is advanced than the later. You may see the detailed comparison at:

The important feature I want to mention here is the Max File Size limitation of the two file system, which may cause the problem we mention in this article. The max file size of FAT32 is 4GB minus 2 Bytes, while the one of NTFS is limited only by volume size, which means you may create a file as large as a partition volume. Now, we see get the sticking point. If you created a file (say a huge DVD video created by DVD Presenter) larger than 4GB, and the file system of the saving partition is FAT32, you will prompt this message.

Then, how to fix it? Here is the solution:

Note: Converting FAT32 to NTFS is one-way only. Once executed, there’s no way to revert back without reinstalling system.
Below the method on how to convert in DOS mode under Windows XP.

1.      Click Start, Run, type CMD, and then hit Enter key to move into DOS window.
2.      In the command window, type “chkdsk x:” and press Enter.
3.      Then input command “convert x: /FS: NTFS /NoSecurity” and press Enter.
4.      After the above steps, the drive format will have already been converted to NTFS.
Note: The “x” above refers to your drive number.

 It’s easy to discover which files system your Window XP operating system uses. Simply right-click the drive icon in the My Computer window（or volume in the Disc Management window）and choose Properties.

Or, you can google the converter utilities on Internet.

We suggest you use NTFS system. You may noticed from the comparison list, it is an advanced file system to FAT32.
