• Sudo apt-get install zip. I see from man zip that it allows me to use a file list: -@ file lists. If a file list is specified as -@ Not on MacOS, zip takes the list of input files from standard input instead of from the command line. For example, zip -@ foo. So I created zip.lst which looks like this.
• To batch convert RAR to Zip, just select multiple files at the same time. Control-click the archive or selected files in it and choose Extract or Decompress. Alternatively, you can highlight files and click Extract in the toolbar. Choose a location on your Mac to save the decompressed files.

WinZip^® makes it easy to create Zip files (.zip or .zipx) that are split into smaller pieces of a size that you specify. There are several reasons why you might want to do this, such as:

Multiple files or folders compressed will end in Archive.zip; How to Open a Zip file on Mac: Double-click the zip file/folder you need to decompress; If you are unzipping a single file, it will have the same file name as the original file but with a number appended. For zip files containing multiple items, the unzipped files will be.

• To assist with large downloads. Some users may have difficulty downloading very large Zip files from web sites, FTP sites, etc. You can use the split Zip feature to break large files into smaller pieces that can be downloaded separately.


• To overcome email size limits, as an alternative to sharing the Zip file to the cloud. Some email systems limit the size of attachments. If you want to email a large Zip file that exceeds your limit, sharing is usually the easiest solution, but, if that is not an option, you can also split the Zip file into smaller parts and email them separately.

To split an existing Zip file into smaller pieces

If you have an existing Zip file that you want to split into multiple pieces, WinZip gives you the ability to do that.

Using the WinZip Ribbon interface

1. Open the Zip file.
2. Open the Settings tab.
3. Click the Split dropdown box and select the appropriate size for each of the parts of the split Zip file. If you choose Custom Size in the Split dropdown list, the Custom Size (MB) field will become active and allow you to enter in a custom size specified in megabytes.
4. Open the Tools tab and click Multi-Part Zip File.
5. In the Split window, browse to the location where you want to create the new split Zip file.
6. Type in the file name for the new split Zip file in the File name box.
7. Click OK.
8. WinZip will create your split Zip file using the size you specified in step 3 as the maximum size for each part. The result will be one file with a .zip or .zipx extension, and additional files with numeric extensions: .z01 or .zx01, .z02 or .zx02, etc.

To create a new split Zip file

You can create a new split Zip file with the WinZip submenu of the context menu.

1. Open WinZip and follow steps 2 and 3 above (unless you know the size is set as you want it already).
2. Highlight the file(s) and/or folder(s) you want to use to create a split Zip file in Windows Explorer or on the Desktop.
3. Right click in the highlighted area and choose Create a Split Zip File from the WinZip submenu of the context menu.
4. In the window that opens, change the file name and the destination if you wish, and choose other options, then click Create.

Notes

• Each of the segments of the split Zip file will have a different extension. WinZip creates files with names like Data.z01 or Data.zx01, Data.z02 or Data.zx02, and so on, except for the very last segment of the new Zip file. The last segment will always have either the .zip or .zipx extension, respectively, based on the compression method used when creating the Zip file (e.g., Data.zip, Documents.zipx).
• To open the split Zip file, open the file with the .zip or .zipx extension. Don't try to open any of the files with the numbered extensions; WinZip won't recognize them as Zip files.
• Once the split Zip file has been opened, you can work with it much as you would work with a regular Zip file, except you can't add any new files or remove existing files. Some operations such as creating self-extracting Zip files and editing comments are also disabled for split Zip files.
• The sizes listed as 1.2MB, 1.44MB, and 2.88MB are approximate. The segments of the split Zip file are sized appropriately to fit on media of the specified size. You cannot, however, use decimal points when specifying sizes in the Other size field.
• The split Zip file format is an extension of the Zip 2.0 specification. Therefore, some Zip utility programs may not be able to open split Zip files. Please see Split Zip file compatibility information for more details.

Are you new to compressing folders onMac? Today we will find out everything there is to know about how folder compression works, how to process it, why it is important and what are the best ways to efficiently and easily compress folders on Mac.

Part 1. Brief Introduction to Compressing Folders

File compression began way back in the 1970s where scientists were searching for ways to reduce file sizes through working with algorithms. Since then, the development of various computing processes and technologies kept on evolving until today.

What is a Zip File?

A zip file is an archive format that is supported by lossless compression. It allows a number of compression algorithms which reduces the file size. Today, we can easily locate a zip file because its extension ends with .ZIP/.zip (for multimedia files: application/zip) and with the zipper icon.

It was first used publicly by Phil Katz in 1989, in replacement to the ARC compression format made by Thom Henderson.

How does compression work on Mac?

If you work with data transfers almost every day, files compression could be your ultimate solution for ease of use, size, and transfer time.

Just like we mentioned earlier, compressing files takes up lesser disk space, and files can be easily sent and received more quickly.

Compression is done by working with the computer codes and has two different types:

Types of Compression

There are two types of compression known today, first is lossless and the next is lossy. Lossless compression is focused more on searching long codes and replaces them with shorter ones and recreates the same exact file.

Lossy compression, on the other hand, searches for codes it can delete and mostly used for multimedia files. A file on lossy compression seems to be identical but is entirely different at the code level.

Part 2. Advantages of Compressing Folders on Mac

Every byte counts if you're short on disk space or when you're sending a large file over the Internet. This is where file compression comes in. File compression has several advantages that users can highly benefit from.

Storage Space

Lossless compression, used in zip file technology, can reduce a file to 50 percent from its original size. Some files such as documents can be zipped and reduced to 90% from its original size. Thus file compression saves you a lot of space in your disk and you can use it for more important storage options.

Transfer Speed

If you happen to notice that all your downloads are in kept inside zipped files, this is because it takes a faster time to transfer these data when they are compressed rather than individually.

These compressed files use lesser bandwidths (the speed used for network transfers).

Cost

Using archives or software for file compression can save you lots of money because it reduces the cost of purchasing a new hard drive for more storage. If all files inside your desktop are organized and compressed, you will have more space to use for other programs required by the system.

Part 3. How to Compress Folders on Mac Using PowerMyMac – Unarchiver

To compress files on your Mac and you got the program installed; all you need is to double-click on the file/s and it will be zipped into .RAR or .72 file format. All files you have compressed and decompressed will have the PowerMyMac icon beside.

Part 4. How to Compress Folders on Mac Manually

Compressing files or folders on Mac is so easy because it already has a built-in compression and decompression option which uses ZIP file format. Each Mac has different compression capabilities depending on its processor. Some file compression can take time especially if you are using older models. Macs with faster processors and bigger RAM can compress and decompress files quicker.

How to zip a file on Mac?
