FileOptimizer v12.60 Updated

FileOptimizer is a broad format file compression tool used to reduce file size without changing the quality, known as "lossless." This is done via wide variety of optimization and recompression tools and techniques. Original files are sent to the recycle bin for restoration in the event the uncompressed version is preferred. A long list of supported formats include audio/video (MP3, OGG, M4A), image (GIF, JPEG, PNG), office formats (DOCX, XLSX, ODT, PDF) and system files (DLL, EXE).

Supports drag-and-drop of files into the window or onto the program icon. Note that by default the program removes metadata for many file types. This information reduces overall file size and protects privacy but is important to some users (e.g. photographers) and file search tools.

A 64-bit version is available within the folder, the author reports the program is functional in WINE, and can be used on the command line.

Looks like version 11.40 phones home on every startup now, regardless of settings, probably trying to fetch some ads, well I'm not giving it a firewall rule so I'll be sticking with version 11.31 for the time being.

@Special do you mean that even if ads are not shown they are loaded?

@Special. Fixed!

It supports the creation and extraction of most common compression formats, as well as modern formats ZIPX and 7Z.

The program's "High Speed Archiving" function will allow you to compress or bypass the files its own algorithm on multimedia files (AVI, WMV, MP3...) or archive files (ZIP, RAR, 7Z...) that won't benefit from additional compression. This can increase archiving speed dramatically. Extract formats supported include 7Z, ZIPX, RAR, ALZ, EGG, TAR, BH, LZH, BZ2, ISO, CAB, WIM, XZ, ARJ, ZIP, Z and more.

To disable 'Start Screen' go to "Settings"-"Advanced" and uncheck "Show 'Start Screen' when Bandizip starts".
To revert to the old tool-bar go to "View"-"Toolbar" and select "Old".

billon on 30 Jan 2018
  • 1MB (uncompressed)
  • Released on 29 Jan 2018
  • Suggested by Checker AppCompactor allows you to compress whole directories including applications, file libraries and zip files. The program is a powerful compression tool that unites 7-zip and UPX inside a user-friendly wizard. For applications, this saves disk space and increases performance when running from a slow media (like flash drives). For archives, this will recompress DLL, EXE, ZIP, JAR, IRC, PYD and BIN files to their maximum compression settings, as well as an option to decompress an app's binary files that were previously compressed with UPX.

All files are tested using UPX's test feature after compressing. Files smaller than 4K are automatically skipped as compressing will not save space on the drive. The standard Microsoft Visual C runtimes are skipped to prevent antivirus false-positives. Advanced configuration can be done with apps in Format.

Note: As UPX will alter the EXEs and DLLs (reversible using the Decompress option in the AppCompactor) and some apps may have issues with Zip or Jar files compressed further, users should backup software and test it after processing.

tommyD: Disadvantages are that it breaks some programs, and it may be slightly more CPU-intensive to decompress libraries and executables on the fly.

I agree with wf; where is operaportable?

7-Zip is an archive manager that can view and create a wide variety of formats. The program includes folder favorites, optional two-pane view, checksum calculator, file split/combine capability and more. Individual archives can be created with high speed or high compression settings, update options (including update, add/replace, synchronize), split volumes and more. Archives can be secured with standard zip or more secure AES encryption.

Although the official archiver for the open, high-compression "7z" format, the program also supports the creation of multiple formats including ZIP, XZ, BZIP2, GZIP, TAR and WIM. It will extract a long list of other formats, among them RAR, CAB, ISO, ARJ, RPM, VHD, VMDK etc.

Normally you would need to know the password to access a passworded 7z archive or to even look inside one, but by using the 7z file manager you can still add stuff into a passworded archive by just dragging & dropping stuff onto it, for example a blank .txt file, that is the first part, then with the use of a simple Hex editor (HxD) you can break the password "lock" if you know what to look for. What I'm saying is, use 7-Zip for your compression needs, but for encrypting sensitive stuff you plan on uploading onto the web, look elsewhere.

Here's my 7-Zip Portable made with my modified version of the PA.c Launcher:

I've added support for shell integration as well as the context menu features. I even added support for file type associations to where you may specify which formats you'd like associated with 7-Zip during runtime. Plus I've added a SendTo shortcut which is available for any file types that aren't associated but are supported for use with 7-Zip.

And yes's still very much portable! Read the ReadMe file on the GitHub project page on how to add associations or how to set the shell extension/context menu features...

SECURITY PROBLEM: 18 Beta appears to work under PortableApps. Download 18 Beta from Use 7-Zip or Universal Extractor to extract files to a new folder, replace PortableApps files in App folder with 18 Beta files.
