File archiver is one of the must-have applications for our computer. It can compress files to save disk space and improve the file transfer efficiency. Meanwhile, it can also be used to extract files from compressed packages downloaded from the Internet. There are already many such programs, including the classic WinZip, WinRAR and 7-Zip. But if you want to try something else, Express Zip File Compression is also a good choice.

Duplicate File Finder is a small, simple, easy-to-use and powerful duplicate file finding program developed by Ashisoft. It can help users quickly find and delete various duplicate files (duplicate videos, duplicate music, duplicate pictures, duplicate documents, etc.) from their hard drives, so as to effectively free up disk space and improve computer performance.

The biggest killer of disk space is not large files, but duplicate files, such as photos, music, videos, eBooks, documents, etc. Large files are actually quite easy to find and clean up, but duplicate files are almost always scattered all over the disk and usually hard to find. It is obviously too inefficient and even impractical to find them one by one by manually comparing the names, sizes, contents and other attributes of a large number of files.

If you run out of space on drive C (system partition) or SSD, or want to slim them down, you can move the programs you installed in them to other places. Direct moving a program does not work properly, and uninstalling then reinstalling a program is too inefficient. The correct solution is: first cut each installed program to its new location; then create a Symbolic Link (which looks like a shortcut with the same name) pointing to the new location in its original location. If you find this a bit of a hassle or are afraid to try, FolderMove can help you automate this process.
