Why Compress/Archive Files?
Save Time
Compressing files can be a great way to save time. Large files can take a rather long time to transfer, especially if you're uploading them online. The smaller size allows for you to transfer quicker. Another advantage is being able to merge all the files or an entire folder into one. This is great for hosting files online, as you will only need to download the one archived folder instead of each file individually. Although some online hosts allow for you to download multiple files at a time this feature is usually behind a paywall.
Efficiency
When dealing with large files, like video, being able to store all the content can be difficult. Fortunately archived files are much smaller than the original counterparts. This allows for you to make the most out of the storage space that you have.
Encryption & Password Protection
Although password protecting files and files isn't limited to archivers it is a great addition. Adding a password protection to your files allows for you to prevent unwanted eyes from seeing your documents. When uploading or sending files on the internet it's a great option to be able to password protect sensitive data.
Email Attachments and File Limitations
Websites and emails will often have attachment size limitations. Compressing your file(s) can help you meet these size restrictions. When emailing it can also allow you to fit more into one email, or avoid using a file hosting site.
Save Money
Online backups are becoming more and more popular, both for personal and business purposes. These services are usually priced by the size of storage needed. Because of this compressing backup files can save you money as you won't need as much storage.
Disadvantages of File Compression
Memory Issues or Slow Performance
Unpacking a compressed file requires memory, some older devices may have issues performing this task. Issues will usually display as a memory or low resource error. There is also the chance that you will notice general slow down when compressing and extracting files. Most current systems should be capable of running multiple programs and archive software at the same time.
Transfering Compatibility Issues
Not everyone is familiar with archive files. Even if they are there is a chance they don't have the right software for all formats. This can cause issues when transferring data online. Compression formats like Rar and Zip tend to be the most commonly used. If you plan on sharing files with other people it may be optimal to limit them to these types. Alternatively you can also send the person a link to 7-Zip with information on how to access the file.
Speed
Accessing a compressed file takes longer, as it needs to be extracted first. If you're trying to access a file quickly this may be an issue. Ensuring that you keep often used files uncompressed can help you avoid this.
Lack of Compression
Each file is different, and because of this some formats don't compress as well as others. Video and photo files tend to already have some level of compression to them. However this is dependant on the format used. Because of this you may see less than desirable compression rates at times.
Virus Threats
People can hide viruses or malicious content in archived files. This could be an issue if you're receiving files from untrustworthy sources. You can however use antivirus software to scan the archive before opening. If you have an antivirus program active on your computer you can right click on the file and choose to scan it with your antivirus.
How to Encrypt a File with Password Protection using 7-Zip
A great option when creating file archives with 7-Zip is the ability to encrypt them. By adding encryption anyone that tries to access the file will need to enter a password. If you are trying to keep a document secure or prevent people from accessing critical information this can be useful.
1. Select the file(s) or folder that you want to archive.
2. Right click one of the selected files and choose the 'Add to archive' option by hovering over 7-Zip.
3. A settings menu will open. Choose the Archive format that you want to use, 7z or Zip is recommended.
4. Near the bottom right you will see a segment for Encryption. Enter the password you want to lock your file. You will need to enter the password twice to confirm it.
5. If you chose 7z format you can also check the box to encrypt file names for added security.
6. Choose your encryption method, some formats may only have one option. AES-256 is a good method however only limited archivers are capable of extracting them. If you are using Zip format you may want to use ZipCrypto instead.
7. Press Ok to begin archiving your documents.
How to Open an Encrypted 7z or Zip File
1. Right click on the file and choose to Extract or Open the archive.
2. You will be prompted for a password, enter it. If you chose to open archive you may not be prompted for a password until you try to open a document.
3. The encrypted file will begin to extract.
AES-256 vs ZipCrypto
Two popular methods of archive file encryption are AES-256 and ZipCrypto. When using archive software like 7-zip you may have a choice between the two. AES-256 offers better encryption however not all archive programs are compatible with it. Whereas Zipcrypto is supported by more programs. This is great as people are more likely to be able to open it without requiring additional software.
Best 7-Zip Settings for Maximum Compression
