|
|
* |
|
|
* To avoid issues with operating systems which did not support large files |
|
|
* (larger than 2 GB) the original Giga file format avoided to ever save gig |
|
|
* files larger than 2 GB, instead such large Giga files were splitted into |
|
|
* several files, each one not being larger than 2 GB. It used a predefined |
|
|
* file name scheme for them like this: |
|
|
* @code |
|
|
* foo.gig |
|
|
* foo.gx01 |
|
|
* foo.gx02 |
|
|
* foo.gx03 |
|
|
* ... |
|
|
* @endcode |
|
|
* So when like in this example foo.gig was loaded, all other files |
|
|
* (foo.gx01, ...) were automatically loaded as well to make up the overall |
|
|
* large gig file (provided they were located at the same directory). Such |
|
|
* additional .gxYY files were called "extension files". |
|
|
* |
|
|
* Since nowadays all modern systems support large files, libgig always |
|
|
* saves large gig files as one single monolithic gig file instead, that |
|
|
* is libgig won't split such a large gig file into separate files like the |
|
|
* original GigaStudio software did. It uses a custom Giga file format |
|
|
* extension for this feature. |
|
|
* |
|
|
* For still being able though to load old splitted gig files and the new |
|
|
* large monolithic ones, this method is used to determine which loading |
|
|
* policy must be used for this gig file. |
|
|
* |
|
|
* @note This method is currently protected and shall not be used as public |
|
|
* API method, since its method signature might change in future and since |
|
|
* this method should not be directly relevant for applications based on |
|
