Advice
- The size of the compressed 7z archive should be smaller than the folder that is created by the data decompression process. This is completely normal and is why users compress files using this format to create a single archive that is smaller in size and therefore easier to transfer.
- Most programs that are capable of decompressing into 7z files are also capable of creating this type of compressed archives.
