Both
7z and
RAR files are compressed archive formats, but they have different software associated with them. Let’s clarify:
- 7z Files:
- These files use the .7z extension.
- They are created using the 7-Zip software, which is an open-source archiver.
- 7z provides excellent compression ratios and supports various compression methods.
- To work with 7z files, you’ll need to use a program that supports this format (such as 7-Zip itself).
- RAR Files:
- These files use the .rar extension.
- They are created using WinRAR, a proprietary software.
- RAR files also offer good compression, but they are less common than 7z files.
- To work with RAR files, you’ll need WinRAR or another compatible program.
Now, regarding your question about deleting the extension:
- Be cautious when renaming files by removing their extensions. It’s generally not recommended because it can lead to confusion and compatibility issues.
- If you have a file with an unknown extension, it’s better to identify its format first.
- If you’re sure that a file is either 7z or RAR, you can try renaming it to the correct extension and then open it with the corresponding software.
Remember:
- 7z files should have the .7z extension.
- RAR files should have the .rar extension.
If you’re uncertain, you can use the appropriate software to open the file and verify its contents.
