Case:
Customers save an important Excel file in the U disk and often edit the file. After editing the file yesterday, the U disk was pulled out without exiting the U disk.Excel file is gone.
Solution:
Because customers often edit the Excel file, the excel file should be fragmented. It is quite difficult to make fragmented recovery for the excel file with a chip code.So you can only scan the entire U disk through a general -purpose scanning software, and finally sweep a few Excel files. Among them, there is just one that users need Excel files, but the content is much less, which can be regarded as 60%.
