PKWare Compression Library Archive Format | N/A | Compressed Files |
The .CMP file extension is associated with the PKWare Compression Library (PCL), an application that provides data compression and archiving services developed by PKWare. The CMP file is used to store data in a compressed format and is created using the PCL software. It is used to reduce the size of files for transmission or storage, and in many cases the files can be significantly smaller than the original form. The CMP format supports several different compression methods including Lempel-Ziv (LZ) compression, and can be opened by several applications, including PKZip, 7-Zip, and WinZip.
Advantages of CMP File Extension
The CMP file format provides a number of advantages over other types of compressed files. For one, the compression ratio of a CMP file is generally much higher than other types of compressed files such as GZIP or TAR archives. Additionally, CMP files often offer better speed when compressing and decompressing, allowing users to work more quickly. Finally, since the CMP format is developed by PKWare, its encryption capabilities are regarded as top-notch.
Similar File Extensions
Other similar file extensions include .ZIP, .RAR, .7Z, and .TAR.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .CMP) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .CMP extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .CMP file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .CMP extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .CMP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .CMP file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .CMP file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .CMP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .CMP file) will be extended to the maximum.
It is also good to check
- if the .CMP file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
