Word documents in editing are likely to be damaged when they fail to save due to an accident or the system is shut down illegally or crashes down, which causes the document to display unreadable code or even become unopenable when it is opened next time. For this situation, we can try to manually repair the document by saving the corrupted file as RTF format or a different version of Word format. But this is not only troublesome, and the success rate is very low. This case, a better solution is to use the Word document auto-repair tool like DocRepair.

As software development companies, their biggest concern is that their software will be decompiled/cracked soon after it is launched, so many developers choose to pack/encrypt their software products. In general, the file size of packed software is smaller, and the program itself becomes more secure. These days, packer has been moving towards virtual machine protection technology, whose greatest benefit is that it can greatly improve the protection strength. Packers employing this technology include Themida, WinLicense, EXECryptor, etc.; While the downside is that it affects the startup and running speeds of program, so it's not suitable for every situation.

In recent years, with the progress of information processing and analyzing technologies, many QDA (qualitative data analysis) programs have been equipped with very comprehensive and perfect functions, and provide us with more possibilities of using software to analyze text and multimedia data. Software can save time, make it easy to find data, and is more standardized. Especially when the data is too much and the analysis takes very long time, the advantage of software becomes more obvious. In addition, the use of software also provides convenience for multiple users to process materials at the same time in a teamwork.
