7-zip Icon

[Marcelene Vasconez]

Ive been using 7-zip for a long time. Any archive that 7-zip recognizes was given a black and white [7z] icon. I just switched from Win7 32 bit to Win7 64 bit, and when I reinstalled 7-zip all of the recognized archives have different icons. They look like folders with a small blue text character on it. I don't like these at all. For me they are easy to confuse with folders and other stuff. The black and white icons from before were very easily distinguishable from other file types and I liked that.

I figured this was due to a newer version of 7-zip so I reinstalled an older version that I've had stored for a long time but the icons still haven't reverted back to the black and white ones that I am used to.

I did find a utility called File Types Manager that can change the icons for specific file types, but it seems as though that still only lets me change the icon for a single file extension at a time (and as of now 7-zip is associated with 35 extensions) rather than on a per-application basis.

Alternately, you can reinstall the latest version (preferable) and use something like the 7-Zip Theme Manager to easily change the icons and much more besides, instead of manually editing the DLLs using Resource Hacker or similar:

I'm sure there are some themes in there with icons you'd like, and perhaps even themes that include the older icons. If not, you can always try creating your own theme using the icons extracted from the older version of the program's DLL.

You get the boring yellow archive files with the blue letter in the corner if you tell 7zip to associate itself with the file extensions. If you remove those associations and then right-click --> Properties on a compressed archive, then click the "Change..." button next to "Opens with:" and select 7zFM.exe (wherever you installed 7zip, C:\Program Files\7zip\ by default), it will associate those archives to 7zip, but it will use 7zFM's icon on those compressed archives rather than the yellow/blue ones you get when you associate 7zip to archives from within 7zip's settings.

I like 7-Zip a lot - it's my compression utility of choice on Windows. I have just one problem with it: it's butt ugly. I'm really kind of reluctant to install it on my fresh Windows 7 system because of its eye-bleeding qualities. Sad, I know, but the designer in me is just too anal to cope with it.

For the first option, you can edit the registry. The icon should be associated inHKEY_CLASSES_ROOT\zipfile\DefaultIcon. The entry is a string with the full path to the file (most probably the 7-Zip executable), and optionally a 1-based index of the icon number to use, seperated from the path by a coma. I know a tool that is helpful if you don't wand to fiddle with the registry manually: WAssociate

I need help how to completely uninstall/delete the 7 zip cause its messing some of my files icon, the drivers pack solution and win setup from usb zip files (zip files with .exe extension) icon has permanently change to 7zip icon no matter how many times I delete and re download my files its still the same and when I check the files properties the file description says 7z SFX I don't know why it happens because the 7zip is already uninstalled and also the 7zip file manager still shows in the windows search bar even it is uninstalled but when I click it nothing happens.

I need to fix it cause the files that are affected are the files that I need in school and I don't want to format my pc just to remove it, I just wanna know how to completely remove the 7zip just for a while cause I don't really want to use winrar.

Hello There! Please refer to the following URL & help decipher the Mystery behind this Surreptitious association of .exe files with 7-Zip? I have never observed that before until I Upgraded 7-Zip to its Latest release--16.00! Why are .exe files showing up with 7-Zip Icon over these? How to restore things to normal? How to revert to the Original Icons? Please Help. URL::::-

Hello Igor! Under the 'File-Associations' of 7-Zip, I couldn't see any such option to either associate or deassociate .exe files with 7-zip!? Therefore, how come a .exe file can start associating itself with 7-zip all of a sudden? Nevertheless, please suggest a way on how to DEASSOCIATE my .exe files from the Shadow of 7-zip? I would like to see the Original-Icons for these .exe files. How to accomplish the same? Help will be sincerely appreciated. Thank you.

Note that each exe files can contain some icon.

And if that exe file contains 7zip icon (icon of 7-Zip SFX module), then you see it.

If there is no icon inside exe file, you must see default exe icon.

Hello Igor! I would like to Confirm that not all .exe files are associating themselves with 7-zip but only a few! & these few constitutes the "Portable" versions of Software Applications, such as--Portable Versions of PaleMoon & Avant Web Browsers! At the same time, I would also like to assure you that before Upgrading to the Latest version of 7-zip, even these 2 were showing up with their Original Icons! Therefore, what changes have been made under the Hood of Latest 7-zip to cast a shadow over this Category of .exe files? & Most importantly Sir, how to DE-ASSOCIATE these few from 7-zip? Help will be sincerely appreciated.

1) Do you understand that if some developer uses 7-Zip SFX module to make installer smaller, then you see 7-Zip icon for that file?

2) Open that exe file with 7-zip as archive via context menu. And then press "Info" button in 7-Zip window.

3) Open C:\Program Files\7-Zip folder in Explorer and look icon for 7z.exe file.

It shows default icon for exe file.

Honestly the icons themselves are not bad, they're well defined, but still a change is needed in my opinion.

I have uploaded a ZIP archive that contains all the assets of the new icons, I've premade Favicons, Program Icons, Banners (Logo and Download), and Uninstall Icon.

I tried to be as close to the original icons as possible, the main difference would be contrast on the logo/banner images, and in other icons it would be presence of anti-aliasing, which is much better than the pixelated variants.

You must run 7-Zip File Manager in administrator mode. Right-click the icon of 7-Zip File Manager, and then click Run as administrator.Then you can change file associations and some other options.

You can get big difference in compression ratio for different sorting methods,if dictionary size is smaller than total size of files.If there are similar files in different folders, the sorting "by type" can provide better compression ratio in some cases.

Note that sorting "by type" has some drawbacks.For example, NTFS volumes use sorting order "by name", so if an archive uses another sorting, then the speed of some operations for files with unusual order can fall on HDD devices (HDDs have low speed for "seek" operations).

If you have such archive, please don't call the 7-Zip developers about it.Instead try to find the program that was used to create the archive and inform the developers of that program that their software is not ZIP-compatible.

7-Zip doesn't know folder path of drop target.Only Windows Explorer knows exact drop target.And Windows Explorer needs files (drag source) as decompressed files on disk.So 7-Zip extracts files from archive to temp folder and then 7-Zip notifies Windows Explorer about paths of these temp files.Then Windows Explorer copies these files to drop target folder.

You're probably using a *.* wildcard. 7-Zip doesn't use the operating system's wildcard mask parser, and consequently treats *.* as any file that has an extension. To process all files you must use the * wildcard instead or omit the wildcard altogether.

7-Zip stores only relative paths of files (without drive letter prefix).You can change current folder to folder that is common for all files that you want to compress and then you can use relative paths:

32-bit Windows allocates only 2 GB of virtual space per one application. Also that block of 2 GB can be fragmented (for example, by some DLL file), so 7-Zip can't allocate one big contiguous block of virtual space.There are no such limitations in 64-bit Windows. So you can use any dictionary in Windows x64, if you have required amount of physical RAM.

There are some possible cases when archive is corrupted: You can open archive and you can see the list of files, but when you press Extract or Test command, there are some errors: Data Error or CRC Error. When you open archive, you get message "Can not open file 'a.7z' as archive"It's possible to recover some data. Read about recovering procedure:Recover corrupted 7z archive

One way is to use the 7z.dll or 7za.dll (available from sf.net for download). The 7za.dll works via COM interfaces. It, however, doesn't use standard COM interfaces for creating objects. You can find a small example in "CPP\7zip\UI\Client7z" folder in the source code. A full example is 7-Zip itself, since 7-Zip works via this dll also. There are other applications that use 7za.dll such as WinRAR, PowerArchiver and others.

Since 7-Zip is licensed under the GNU LGPL you must follow the rules of that license. In brief, it means that any LGPL'ed code must remain licensed under the LGPL. For instance, you can change the code from 7-Zip or write a wrapper for some codefrom 7-Zip and compile it into a DLL; but, the source code of that DLL (including your modifications / additions / wrapper) must be licensed under the LGPL or GPL.Any other code in your application can be licensed as you wish.This scheme allows users and developers to change LGPL'ed code and recompilethat DLL. That is the idea of free software. Read more here: can also read about the LZMA SDK, which is available under a more liberal license.

I discovered the icon index that I needed was #238 by trial and error by temporarily creating a new shortcut (right-click on your desktop and select New --> Shortcut and type in calc and press Enter twice). Then right-click the new shortcut and select Properties then click 'Change Icon' button in the Shortcut tab. Paste in path C:\Windows\System32\shell32.dll and click OK. Find the icon you wish to use and work out its index. NB: Index #2 is beneath #1 and not to its right. Icon index #5 was at the top of column two on my Windows 7 x64 machine.
