But when the application or the operating system crashes while a .chz data file is being opened, a ChArc compressed archive data corruption occurs. Sometimes, parts of the file, or its header is not properly saved in the disk which causes application failure and data corruption. Physical problems in the storage media may also be the cause, as well as hardware malfunction, viruses, software errors and even human error.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .mpp. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
