Ewout For me, this proved for the first time "for sure" that adding to PATH generally means adding to the user path , not to the system path , as the setx is adding to the user path. It might be clear to everyone, I did not know it even after dozens of times changing the environmental variables. My 7zip folder includes an Uninstall. I would recommend you to isolate the command line tool from those other ones.
Regarding Phil Street's post: It may actually be installed in your bit program folder instead of your default x64, if you're running bit OS. System will then read all the "exe" files from there and make it available to the command line make sure to close the current command lines and start a new ones because changes aren't available until restart of those command lines.

How to Open 7Z Files in Windows, Mac, and Linux - Free file extractors for ZIP, RAR, 7Z, TAR, & other compressed formats
How to zip files - Compress and uncompress files - If you are using Ubuntu Linux:
The lowercase L is used to list the contents of archives and you probably will not need to use it often. I thought I would test it and show an example. Next: This shows the listing of a solid archive. The originals are bytes and bytes. They compress down to bytes.
Command t. Here we use the "t" command in the 7z program. This command allows you to test the integrity of archives. It stands for 'test' and is much less useful than the "-t" switch. Don't confuse the two. This one is used for diagnostics. Command u. The "u" command in 7-Zip stands for update. This is a useful command and is great when you want to replace old files in your archive with newer files.
This prevents needing to decompress and recompress the entire archive. Warning: The "u" command doesn't work with solid archives. A solid archive is one where all the files are compressed together. So: You cannot update specific files in solid archives with the "u" command. Solid archives are limited. Switch m. We can change the optimization settings in 7-Zip on the command line.
This is the most important and useful option you can use. It specifies the method of compression. Here I will show a bunch of options, and also some examples. Switch m, advanced. Here are advanced compression method -m switches. The first three are usually of limited use, but you might benefit from tweaking them.
My experience is that manual optimizations to these options doesn't produce big benefits. Switch -mfb: Specifies number of fast bytes.
Sometimes helps with "sparse" files. Don't bother. Switch -mpass: Number of passes for deflate compression. Don't bother with this. Automatically set with levels. Switch -md: This specifies dictionary size. It is automatically set, so don't bother. Switch -mmt: Enable multithreading. Use if you have quad-core and a huge archive. Specify "on" or "off". This may be enabled by default. Command x. This command is like "e" except it preserves the full paths.
If you have an elaborate or important directory structure, use this option. This would be most useful for system backups or really big backups. Here's the example syntax. Switch t type. Here I show how to specify the precise archive type you want to create. Note that you can specify any filename you want for any type.
But some extensions are recommended—they are standard. Also, the 7-Zip manual provides some useful examples for type switches. It shows the -tiso and -tudf switches. These are not the most common. Almost all of the examples in this document use -t switches. Solid archives. Solid means all the files are compressed as one. It makes it impossible to use the "u" command to update individual files. This is the default so you won't often need to specify it.
Useful when you need to update individual files. Will reduce compression ratios normally. You can change many values and switches on 7z archives, with endless permutations.
Some things you can change are dictionary sizes, FastBytes values, MatchFinder values, and filters. Normally you don't need to deal with these. With the 7z format, you can specify the algorithm. PPMd is fast and effective for compressing plain text files.
It is ideal for large collections of Word documents. PPMd does not perform as well on files containing binary data. They are useful and higher is normally better. They are not normally useful. When should I use PPMd? You should use PPMd when you have a large corpus body of text. This could include HTML or other formatting, but plain text should dominate.
Example commands. Here I show the example compression commands from the 7-Zip manual. I demonstrated simple ones at the start of this document.
These are more complex. We use more features of the 7-Zip command line. Example of 7z format. This next command line shows how to create a solid 7z archive of program files executables.
It uses multithreading mode, which means it will be fast on a dual core machine. Create PPMd archive. PPMd is an extraordinary algorithm for compressing text and is relatively new.
Here I show a command in the 7-Zip manual that compresses all the text files in the working directory. It creates a PPMd archive. Tip: The command is useful because you will normally want to only compress text files with PPMd. Switch o. We show the "o" switch on the 7-Zip command line. Sometimes you do not want to extract to the current directory. This is where -o can come in handy.
Use this to set the destination directory. Switch p. We can use the "-p" switch, which refers to the word "password". This is really helpful when security and encryption is involved. You can specify a password on the command line. The syntax is a bit funky. Opening password-protected archives. This next console output shows what happens when you try to open the password-protected archive.
Header encryption: Add -mhe to encrypt headers. The password command will automatically deal with encrypted headers. More switches. Here we take a closer look at more switches that are of limited use.
They are useful to know, however, if you ever need to use them. Usually you can do better just by using the defaults that are slightly adjusted for your requirement. Switch -ssc: Specify case-sensitive mode. The default is -ssc- on Windows insensitive. The default is -scc on Linux sensitive.
Switch -ssw: Compress locked files. You can try this if you have problems opening files. Switch -w: Set working directory. You can use this when you want to specify temp folders. We can use case-insensitive file names in the 7-Zip command line. For those of you who use both Linux and Windows, the case-sensitive option is useful. I will show my own example here with some explanation. Switch v. You can use the "v" switch on the command line.
In data compression, a volume is a segment of a data set that is a certain number of bytes long. The volume switch specifies the exact size in bytes, kilobytes or megabytes. Also: You can specify sequential volumes with the "v" switch on the 7za. Switch ao. The "ao" switch allows you to specify whether you want to overwrite old files. Be careful—you cannot restore an overwritten file normally. It takes another argument. Back up your data by copying the files in your file manager first.
Switch -aoa: This switch overwrites all destination files. Use it when the new versions are preferred. Do change variables as per your need.
