Over all this is a very good program, how ever unless I missed it, I cannot see theability to turn all the folders I put in the table each in to their own archive not one big archive. Also the buttons in the tool bar are not labeled for voice over users. Help tags would be nice though if lables cannot be provided. Thoughts?

@Lee_Xiao: Entropy should work fine with unicode archives.

In fact, it is one of the few archivers which can auto-detect non-standard encodings in older zip archives. Could you please verify that the "Enable automatic character detection" preference is enabled in the "Advanced" section of the preferences?

I don't see .dmg creation and compression which I use for its easy mounting, viewing and access.

Nor .zip7 which has the best compression.

Hi there,

I assume you meant 7zip (.7z), rather than zip7? Entropy does supports creation of 7zip archives - you can select it from the popup menu when saving.

DMG creation is not supported by Entropy, primarily because it is a disk image format rather than an archiving format. You can use the Disk Utility provided with OS X to create DMGs. (you can, however, use Entropy to open up DMG images for inspection by pressing the shift key).

If you have any questions, please feel free to get in touch at support@eigenlogik.com

Yes I meant 7zip, slip of the keyboard.

Disk Utility is slow and extremely clumsy , it takes 2 pases to make it compressed/and or passworded .dmg.

.dmg files are readily accessible disk image archive which can be compressed, thus giving the full benefits of keeping everything in one quickly viewable archive that saves storage space as well. I use it bundle up projects that are finished but need to be revisited at intervals, maybe to get just one of the enclosed files.

I also use .dmgs to hold my tutorial courses all neatly arranged and ready to go.

Simply one of the best. Is the only one that manages Zip, RaR opening them, adding files, creating archives, in those formats and more.

Of all the archiving apps (ones which can CREATE and extract) I've tried, this one pleases me the most. It is able to handle files +4GB, which is important to me because I often need to archive large disk images, and have to break them up so they can be sent or stored on Windows FAT32 drives.
The ability to define presets is fantastic and makes it easy to select the one that fits the job, i can define a preset for large images that doesn't waste time compressing (just chunks it up), into predefined sizes, like 250MB, or 1GB.

The only other tool that comes close but doesn't have as nice a GUI is Ez7z.

sArchiver never handled +4GB files and Entropy appears faster than BetterZip.

I guess $20 is kind of a lot for an archive utility. But that's the only possible gripe I can see about this program.

Entropy handles both creation and extraction of all the major formats, and quite a few minor formats. Its default settings are sensible, but can be configured to suit lots of different methods of work.

Because almost everything I need to do has been added to the Services menu, I hardly ever actually launch Entropy directly. But that's the way a utility should be: unobtrusive, waiting to do what you need, and then out of the way again.

Great, great program.

Very impressed with Entropy - in particular the speed in unzipping a file. It also has some beautifully styled touches that really add to the pleasure of using it. The program gets out of your way too - it doesn’t need to open the archive before it unpacks it. Finally it supports a great variety of formats, including some of the more rare ones.
Downsides? I don’t particularly care for the icon that it gives files. Given the program is so elegant, the file icons seem quite clumsy. But this is a little thing, and it doesn’t affect the functionality.

Could you add the ability to add a comment to an archive, that is viewable in Winrar? I've not seen one app that could do that.

Since upgrade to the version 1.4.1, i'm no longer able to open encrypted files with password, there was a dialogue window which told me to type in the password but now it just doesn's respond any more, could you please verify ?

Yes, v1.4.1 has a critical bug which can cause Entropy to deadlock on opening header encrypted archives. This has been fixed in the next update which will be released very soon.

In the meanwhile, if you auto-extract the archive (either via preferences or the cmd modifier key), or manually open it through the File->Open option (rather than double-click or dropping on the dock), it should work correctly.

Thank you for your tips i've tried the latter one, it works indeed, anyway i'm looking for forward to the next update !
By the way, do you guys ever consider to release a free stable version, because to me it seems there are still a lot of users who had never hear about this awesome software !

Max_G had trouble on 21 Mar 2012
Tried, looks good. One thing unclear though: can I batch compressions? I would like to drag, say, five folders on the program-window and save them as separate (encrypted) files with one click. Is this possible?
Thanks,

Eigenlogik (developer) replied on 18 Mar 2012
Thanks, I got the feedback report,

The problem is caused by a bug in Entropy's concurrent archive handling feature introduced in v1.4.1. In brief, it causes Entropy to deadlock when dealing with header encrypted archives (where both the data and the filenames are encrypted), when they are opened a certain way.

A fix for this will be released soon.

In the meanwhile, as a temporary fix, you should be able to bypass the problem by using the auto-extract override key ( i.e., press the CMD key while double-clicking on the archive in Finder), or manually opening it through Entropy's main menu ( File > Open ) rather than via Finder.

Let me know if you have any questions.

Entropy 1.4.1 stops responding on password-protected rar files (after the correct password is entered). The Unarchiver handles the same file without a glitch

Is there any error message logged in the console? (If you send a message via the "Help > Submit Feedback" feature, it will automatically include any logged error messages).

Also, does this problem occur with just one specific rar file, or all encrypted rar files? If it's just one archive, would it be possible to download it for testing?

Yes, the feedback reporter will include any logged error messages from previous crashes.

Also, how was the extraction triggered ( for instance: opened and then clicked on the extract button, or auto-extracted, or dropped on to the dock icon... )

Entropy is my default archive manager, so I just double click on the archive to open it. Actually, it gives me a beach ball right away - without prompting for the password

umm... what happened to the "quit on last window closed" in 1.4?
After closing the last archive window I now have to quit Entropy manually.
I hope this isn't a newly introduced 'feature'?

Eigenlogik (developer) replied on 10 Feb 2012
The "quit on last window closed" preference was deprecated in v1.4.0. The primary reason for it is that there were a few subtle "gotchas" involved in having that preference enabled. Incidentally, based on feedback, a significant number of users expected Entropy to behave like other OS X apps and survive the last window close.

So starting v1.4.0, Entropy follows the standard OS X convention. It auto-quits only if it was launched via auto-extract or the services.

Mkay replied on 10 Feb 2012
disappointing really.
I don't know about the 'significant number of users' but this is my typical use of Entropy (or any other unarchiver):
- I open an archive
- extract/drag and drop the files I need
- close the window

Why would I want to keep an idle app running in the background?
Looks like I have to roll back to 1.3.9
burypromote
Eigenlogik (developer) replied on 10 Feb 2012
Entropy's new behavior makes it consistent with other Mac Apps. By convention, if you don't explicitly quit the app (say, using CMD+Q), it indicates the intention that you want it to persist for some reason - perhaps to create a new archive (CMD+N) without relaunching the app, or open one (CMD+O) without using Finder.

That said, I do agree that "close on quit" was a useful preference. Once all the issues with it have been ironed out, it will be re-introduced.

There are problems extracting gstencil-files like the one downloadable from this site: http://graffletopia.com/stencils/414

Extracted with Entropy.app and opened with OmniGraffle leads to an error message that there is no file content…

Extracted with Archive Utility.app - no error.

Eigenlogik (developer) replied on 11 Jan 2012
The problem here is actually the name of the file rather than the contents.

When you auto-extract that particular archive, Entropy creates a sub-directory for it which is named "wireframe_sketch.gstencil". However, since it has the ".gstencil" suffix, Finder treats it as a package file rather than a folder. The actual .gstencil file is inside this folder (which you can access by right-clicking and selecting the "Show Package Contents" option).

The next update for Entropy (v1.4.0) includes smarter sub-folder creation which is package-aware, so you won't have to worry about issues like this.

Currently, Entropy extracts everything in a given archive. If it happens to include the "__MACOSX" folder, it gets extracted too. ( These are added by OS X's built-in archiver. More info here : http://superuser.com/questions/104500/what-is-macosx-folder )

The next version of Entropy will allow you to skip extraction for these files.

Hi
I purchased via MacUpdate etc etc, and I am not sure if its properly registered or not. Under license I select, and its offer a window to register as i am on trial??
I have a serial key form MacUpdate but that just gives an error if I try register.
I also cannot for the life of me, find/view an option to select my archive file type nor encrypt.
i am guessing this may be due to the fact it loks like I have the trial version.
Am i right and what am I doing wrong?
Don't normally have issues installing etc. Main reason I purchased it was for the encryption of files, but its just not there!
Any help appreciated
thanks

Hi Laurence,

For the license registration, please make sure that you enter your name exactly as it appears on your mupromo receipt. If entered correctly, it should display "Entropy is registered".

For the archive type and encryption:

When you save an archive, you can select the archive type from a dropdown. Once you click on save, you will be presented with a new window where you can enable encryption. Here's what the process should look like: http://cl.ly/0Y2S143g101A172C0W0C .

If you encounter any problems, just send me an email at support@eigenlogik.com.
