Identify if a file is packed or not

[Axxy]

Hi

Is there a plugin that can identify if a file is packed or not?

I'm not interested in identifying what type of file it is or it's contents, just if it is packed or not and what packer it is if possible.

Scenario:

Folder contains 1000 text files. Prefix is .txt for all files, but some may be packed, majority aren't. I'd like to identify those packed ones. Probably no exotic packer used, i.e. zip/pk, rar, arj etc. Just be quicker to find the packed files and unpack in a TC window.

This makes no sense. With F3 you can see if whether is a text file (or not). Files are recognized by their extensions like .zip or .rar. When someone makes a blooper by giving them the extension .txt TC is not there to solve this problem. Besides you cannot be sure that an packer is used, e.g. an executable is also unreadable.

So Press F3 on a 1000 files to see if it's packed or not?

The first 2 or 3 bytes will tell what packer was used, RaR, PK, ARJ etc. This was something I just discovered, that some files were packed, I just wanted to identify those files, with a plugin (if there was one) and not TC per se. Yes I can be sure a packer was used because the first 2 or 3 bytes tell me so. Everything is a data file not an executable. Some of these files are from retro machines like the Amiga, so this was the norm back in the day for files to be packed like this. Mostly the files I've seen so far were PKzip type. I can't search for the string PK because the files could contain lots a references to PK in them.

To find zip-compressed file you can do the following

Open the Find files dialog
Activate the "Find text" field and write: ^PK
Check the "Case sensitive" boks.
Check the" RegEx (2)" boks.
Start the search - it should find all files that has PK as the first two characters - as zip-compressed files does.

To Search for rar-files use: ^Rar
To Search for 7z-files use: ^7z
To Search for cab-files use: ^MSCF

It is NOT fool proof - but should help if the other non packed files are genuine text files

Hi

As you say, not fool proof but much closer in the number of hits (or lack of) than I was getting making it easier to check. Thanks a lot, appreciated..

Axxy,
The TrID_Identifier plugin is very useful to identify various file types.

With the plugin encinfo: http://totalcmd.net/plugring/EncInfo.html you can search for binary or text files.

This plugin gives me no results.
The trid tool and its library are installed in the plugins dir as requested
and work from a command line.
A custom columns view with all available fields only shows "-"

Utility and definitions should be in "TrID" subdirectory of the plugin.

Anyway this plugin is sometimes very slow - especially for large files.
For quick identification i mostly use DecHex plugin - https://totalcmd.net/plugring/decHex.html

Thanks for the tip, it works now.

EncInfo that @petermad mentioned is most suited to what OP is asking. It can easily identify binary files, either by searching for those or as custom column info that can be sorted upon.

Afterwards, for manual identifying type of binary file, plugin Textline can be used. It displays the first line of the file in the custom column.

Use WDX part of Total7zip packer plugin - can identify most popular packed files regardless of extension.

(manual installation needed)

You have to manually add something like this to the [ContentPlugins] section of your ini file:

Code: Select all

xx=%COMMANDER_PATH%\PLUGINS\wcx\Total7zip\Total7zip.wcx

Rreplace xx with the next free numer in that section.

Or just copy Total7zip.wcx to Total7zip.wdx to make it visible in TC intall content plugins windows.
