IFFL

This is more of a cracker question but I know someone reading this will know what this is. What does the acronym IFFL stand for and what is it?

its purpose is to save space on disk. a disk is organized into tracks and sectors. now a file's last sector will be most of the time not 100% used. (same problem as on HDDs, many small files eats up more disk space than their size) IFFL chains together many files into one big one to avoid wasting sector space at the end of the files. You have a special loader routine that can handle this, and a tool to chain&save files.

Tried to parse that post, but the ackronym wasn't really explained as far as I could see.
IFFL appeared long after my time, but I always though it stood for "In File Fast Loading" or something like that.

As for what it does, I believe that it can be explained as random access to files contained in a single large .prg.

Using the abbreviation IFFL makes following a T/S chain appearing like rocket science ;)

the funny thing is that early IFFL linkers often didnt even save space at all, since they really only linked several files into one, including the gaps =)

Some other variations it can stand for:

Interflexible File Loader
Interflexible File Linking
Integrated File Flexible Loader

According to this: http://www.zds-bayern.org/gp/history.htm

Antichrist claims to have coined the term IFFL:
"Snacky also invented a new method of packing multiple small files into one big file. We called this new technique IFFL, or Interactive Flexible File Linking. I had come up with that name because I didn't quite understand the procedure."

Maybe used in this: Forgotten Worlds +11?

Any way, it seems that the original "IFFL" was indeed just stacking a bunch of files end-to-end into one file. No high-tech in-drive loader stuff.

High-tech loaders stuff was usually kept out of earlier cracks for compatibility reasons (SpeedDos/DolphinDos/etc...) anyway , so it was probably a deliberate choice.

indeed, like he claims to have "invented" some other terms (like the infamous typo "graphician", lol)

also the technique wasnt invented by snacky at all, it was used in (original) games long before he wrote his iffl tool.
