Compressed files are safer when transferred or stored, because you can set up password protection and other settings for compressed files to protect files.However, Win7 file compression skills also have their disadvantages, such as: 1. Files may be lost or damaged after compression 2. Compression calculation and decompression will take up a certain amount of CPU and memory resources. 3. If the compressed file needs to be modified or accessed in time, it needs to be decompressed first. It is relatively inconvenient to conclude that as a common technique, Win7 file compression is very frequently used in our daily life. This article introduces the specific operation method of Win7 file compression and its advantages and disadvantages. I hope it can be helpful to you.
