Why not just go to your browser history and search there all links from this forum? I mean you know that it was a week ago, so just search by links which are visited least 7 days ago.

The document I was reading I believe it was on my computer. I think I downloaded this document quite some time ago, so I would have to look on my browsing history maybe quite a few months back, maybe a year ago(?) and not look just for a week.

Could you mean how to spot compression algorithms with your eyes? That's an archived link in the Tools for Repacking thread.

Thanks for your suggestion. But this was not the content of the document.

I believe the document discussed the various types of (pre)compressors and related software for use with certain file types. It went into some detail as to which was the most appropriate software to use for the file types to be processed and perhaps suggested software settings as well.

xtool Can't Handle JPEG files?

xtool supposedly is capable of handling (all) files compressed with zlib. JPEG files are usually compressed via zlib I believe, but xtool seems incapable processing the JPEG files?

Precomp, by Christian Schneider, is capable of processing JPEG files, but xtool is not for some reason(s).

Can someone please explain why xtool can't process JPEG files (properly)?

Thank you.

DiskspanGUI is probably the best bet.

Still available special offset-shifted file compare tool??? (File sizes differ smaller than 1KB.)

Read two file started in predefined text or hexa code to file ends.. (Ex: Two WAV files compares, compressed non-standardized tools or etc...)

Quick example (not available the offset-functions):

"fc /b start=data file1.wav file2.wav" or "fc /b start=64617461 file1.wav file2.wav"

start -> start offset reading from two comparable files, reading to file ends, ignoring previous bytes before the offset value. With(in/out) added extra switch, "end=0" aka read files to file endings or "end=X" read files to "X" offset points. (reading two files before file ends.)

A similar question was asked here, almost ~20 years ago: https://www.ghisler.ch/board/viewtopic.php?t=8523

Where should I get started if I want to compress a game and have no indea what the best tools for it are? Looking at the Tools for Repacking thread there are LOTS of tools to try, are there any I should prioritize trying, or just take the few hours to go through all of them and see what does the best?
Thanks in advance

First you have to know what data you are dealing with.

From there on you have to know what tools you have to use.

However you can always ask here what game you are working with, then users will probably tell you something about it.
