New Maximum File Sizes

Release 5.3 includes increased maximum file sizes.

Overview:

The internal pointers that Appx uses in the Appx I/O files are only 32 bits in length. This limits file sizes to 2**32-1 bytes, or approximately 4 Gig. A new file type has been added that uses 64 bit pointers, increasing the file size to 2**64-1 bytes, or approximately 16 exabytes (16 billion gigabytes).

NOTE

Due to an APPX bug in Windows platforms in 5.4.5 and earlier, we recommend you upgrade to 5.4.5.a or higher if you are running APPX on Windows and using FMS type 9 files. Non Windows platforms are not affected.

Usage

Because of the internal differences in the file formats, you must export any existing data, then change the FMS type to '9':

Next, import your data with the 'Replace' option:

This will initialize your file in the new format and import the data.
