Was contemplating buying this, but just noticed the comments in the "WHAT'S NEW" section for Version 1.4.1. "Improvements - Package-folders are now atomically extracted". "Atomically Extracted" you say !! Sod that.. I don't need a Chernobyl/Fukushima in my neighbourhood, but at least with this version of Entropy you can guarantee it will "nuke" large files :-)

:)

In that context, "atomic" implies that package folders are overwritten in their entirety (as opposed to merging with the contents of the folder - that way you don't have stray files left behind). Also, if the extraction fails, the original package is left unaltered ( similar to the concept described here: http://en.wikipedia.org/wiki/Atomicity_(database_systems) )

Hello, I just downloaded it from your website now for testing and I can't find the menu to fast create compressed files, inside the Finder.
Maybe because I'm using a trial version or maybe it is TotalFinder's fault?

Thank you very much.

The option is available under Finder's "Services" menu. Select the files you want to compress in Finder, right click, then under "Services" select one of the "Archive as..." options.

If you just installed Entropy, there is a small chance that Finder hasn't refreshed its service menu options yet. Restarting Finder should fix that.

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,
Max

Saving each folder as a separate archive automatically is currently not [directly] supported. You can automate the creation of an encrypted archive to a single click though, using the "Quick Save" feature. Once enabled (in preference under archiving), you can enter a password for encrypting your archives.

For non-encrypted archives, you can do one better and use Entropy's Finder integration (Right click on the folder in Finder, then Services > Archive as ).

Finally, since Entropy supports AppleScript, it is possible to do exactly what you want if you're familiar with scripting. Then, using Automator you can create a dock icon which will create separate encrypted archives for any folders you drop on it. For more info on scripting, check out http://www.eigenlogik.com/entropy/scripting.

I get this error whenever I try to include any kind of .DMG file in an archive: http://i.imgur.com/cgHUJ.png

Don't know what the problem is. Most other archivers have no issue with .DMG files.

The only error message in Console regarding the matter is the following:

"2/29/12 5:34:14.335 PM Entropy: [Iridium] Could not move archive to the final destination"

Based on the message, it appears that the archive is created without any issues, but Entropy doesn't have write access to the save location.

Could you please make sure that you aren't accidentally attempting to save the archive to a mounted dmg? (They are usually read-only locations). If you save the archive to your desktop, do you still encounter this problem?

xXAkumuXx replied on 01 Mar 2012
My default save location is the desktop. Doesn't matter how I try archiving the .DMG, it could be in a folder with other items, it could be by itself, doesn't seem to matter. I get the same message regardless. All I'm doing is pressing Save like I do with all my other archiving, but if a .DMG is in the list, I get the I/O error. I'm not sure what's happening. Kind of weird.

Eigenlogik (developer) replied on 01 Mar 2012
That does seem rather strange. It might be a permission issue with the DMG file itself.

In Finder, right click on the DMG and select "Get Info". Under "Sharing and Permissions", make sure it says "Read & Write" next to your username.

Also, could you please check if the built-in compress option in Finder works for this dmg file?

xXAkumuXx replied on 02 Mar 2012
Well I'm stupid and you were correct. I had the default unarchiving location set to the Desktop. I had the default Save location set to Macintosh HD. Therefore, I was getting the I/O error. I should pay attention to my settings next time. All is well and thanks for the help.

Thanks!

For security reasons, Entropy does not allow direct extraction to system-protected paths (user-granted privileges still pose certain risks.)

Under certain circumstances, the current version skips the error message that explains why the files weren't extracted. The upcoming update fixes that issue.

I love entropy...it's the perfect mac replacement for old winrar users like my. But i would like a feature that permit (in auto-extract mode) to extract in the same place if in the archive there is only one file and create new sub-folder if in the archive there are more than one file. I hope only in this new feature, for the rest is excellent.

Alex1986 replied on 24 Dec 2011
Thank you for the reply. I've find another thing that, in my opinion, i think would be better to change. It's the name of the folder that entropy create when i extract files from a multiple part archive. When i extract for example "xxx.part1.rar" entropy creates a folder named "xxx.part1" and i think that would be better it creates a folder named only "xxx" without the indication of the part that i've used to extract the entire multi-part archive.
If you don't want to remove completely this thing i think that you can implement an option to chose what method it's better for each.

Other minor thing is the inclusion of extraction percentage.
burypromote
Eigenlogik (developer) replied on 26 Dec 2011
The extraneous ".part" suffix issue has been fixed.

Entropy uses a progress bar since most people find it more intuitive than the numerical percentage value. Currently, there are no plans for changing that.

Is there any particular reason why you would prefer to have the numerical value displayed in addition to the progress bar?

Alex1986 replied on 26 Dec 2011
It's only because i use large size files, so i like to see at what point is the extraction/compression with a numerical indication in addition at the bar, because for me is more intuitive.

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.

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.

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?

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.

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.
