Only the 7z and zip archive formats support anything above a store compression level, so if compression is desired, select one of these two formats. As more processing power is required to compress the objects, so also is the amount of resources needed to decompress that same file. Similar to changing the level, the number of CPU threads used can be altered to, thus changing the amount of memory usage for compressing.
This helps utilize all the CPUs you can to compress the objects at the fastest speed possible. This is helpful if compressing many large files that could be sped up using multiple processing units.
Again, this is only available for 7z both SFX archives and regulars and zip files. If an archive file is too large for putting on a CD or DVD, consider the option to split it into different volumes. The total size before compression was MB. With the compression level set to ultra, the resulting archive file was MB in size. This is a good compression ratio that can drastically save time while uploading for sharing this file, for example.
If too much is going on at the same time while using the allocated memory and CPU power for compression, the computer may temporarily lockup. One way to see if the archive if finished without terminating the process early is to see the resulting filename in its destination directory. The 7-Zip icon and proper file extension will be present on completion. Enter a password, if required, and optionally select an overwrite decision in the even files are already detected in the destination directory.
Now the extracting progress window will display. The other method of extraction is using Windows Explorer. This is where I find many people choose an undesired option. The only difference from this option and the one just previous is that the results are contained in a nice folder for easy identification of where they came from.
This will put the resulting files and folders in recognizable folder names in the same directory as the archive files. At the same time, it provides a toolbar with a drag-and-drop feature. It is possible as well to switch between a single or even dual-pane view. Now, we will move on to properly use 7Zip both for compressing files and extracting them.
When extracting files, there are 5 straightforward steps you need to do. Just check the instructions below. Few of its remarkable specs are:. These are the spec sheet that made 7Zip a strong competitor among the leading compression tools on the web.
The best part, 7z is available and downloadable free of charge! Start to enjoy the lowest compression at no price.
Very ambiguous. May I make a suggestion? I am trying to learn to use 7Zip. Search on 7-Zip forum:.
