Solution:
1. Select the RAR package compressed by the compressed file and put it on other disks with space, such as the DEF disk. The method is: right-click your compressed file-browse-select the drive letter.
2.cclean, if the cleared space is still small, it is recommended to slim down the system. There are many slimming softwares on the Internet, and Jinshan's is recommended.
3. Change the computer's temporary file directory (if there is no change) from disk C to other disks. Take XP my machine as an example:
Right-click My Computer-Properties-Advanced-Environment Variables-set the TEMP and TMP in the XX user variable to other disks with more disk space (remember to set your own folder before setting).
