I'm fairly new, but I use a free application built by the British National Archives called DROID (Digital Record Object IDentification).

It's a very simple tool that uses signature files to detect file formats. It's not perfect (for example, I have quite a few mp4s it won't detect and have recently submitted a request for them to update their mp4 signature), but it's able to return data for most of my files and it's always accurate (in my experience) when it specifies the format.

I threw a bunch of files in a folder and scanned them so you can see the output.

As you can see, it found most files and even looks inside a non-password protected archive to give info on contained files as well.

DROID can be downloaded directly from the UK National Archives site:
https://www.nationalarchives.gov.uk/...records/droid/

Another application called TrID. It uses an algorithm to find similarities between files in order to determine filetype as opposed to looking for specific hard-coded headers. It's available as a command-line application:

or with a GUI:

I hope these are helpful for you.

Exe To Bat
 

Asking it bit late, but, is the reverse possible?? Like a exe to bat?

=> perhaps, when your exe file was a bat file before

Many repackers daily use ZPAQ compressor?? Few weeks ago released the specially modified ZPAQF release, added/modded in 1,4,8 bit images compression optimizations. Speedup are ~40% faster and ratio gains ~1-6% than orig ZPAQ 7.15 version.

See this: https://encode.su/threads/4369-Under...ng-zpaq-models
or directly the src: https://github.com/kaitz/zpaqf

One problems: Not available compiled binaries.

UPD: kaitz released in previous days new zpaq7.15.2f version and x64 compiled binaries. The EXE file instant crashing. I need AVX/AVX2 capable CPU??

Hello
I like to use RapidCRC and blake3 for my repacks.
The problem is that this software suffers from the lack of command-line operation.

To create my files, I now use b3sum.exe which can generate these files.

FMX Style Converter
 

Hi Guys, I designed and created a program discussed with @audiofeel (GUI version of the beta), which allows you to convert (both from the command line for the more experienced, and from a Graphical Interface) FMX 2.5 styles from Indexed Binary (*.fsf) to Raw/Plain (*.style) and vice versa to be able to EDIT them manually, without having to download RAD studio or Delphi. The download of the program(s) can be found HERE on my site. The password is obviously "Felix_550" (without the quotes). I hope it is useful! :D;)

xxHash3 hash
 

Hello guys!
I’ve been experimenting with xxHash3 and got help from AI — the results turned out to bee OK

This is a simple xxHash3 hash generator and checker, I decided to make it open source because I’ve used it in some of my repack projects, and it works great.

Feel free to do whatever you want with it

Enjoy! 😄

Interesting stuff, do you have any benchmarks? It's not very lightweight at more than double the size of QuickSFV, but if it's faster it may have some merit.

you can find somme becnhmarck here is a link : https://github.com/pombredanne/xxHash-3 ;)

Not sure why I didn't just search it up myself, apologies! After some research, and testing on nvme & sata SSDs and some slower HDDs, I'm pretty blown away by how much faster it is, whilst still have a high bit-level sensitivity. So much so that I'll be researching (or start development on) a GUI with feature parity to QuickSFV, as well as adding support to my shell extension tool (that currently only supports more traditional algorithms), thank you to opening my eyes to alternative algorithms!

No need to apologize! It's great, I'd really love to see your GUI, that would be super useful :D

New "LOLZ-killer" compressors??

Few days ago released new compressor, named in OpenZL for structured data.

Windows/Linux binaries (x64 only) not available, this complicated sorce codes only.
