A CSV (comma-separated values) file is a type of text file that uses a specific format to save data in a table-structure format.


CVS files are often used when data must be compatible with a wide range of programs. CVS files can be opened in text editors, spreadsheet programs such as Excel, and other specialized software.

Step 1. Please go to the following paths to locate your desired Excel temp files.

  • For Windows 7: C:\Users\UserName\AppData\Roaming\Microsoft\Excel

Step 2. After clicking File History, select the “Restore your files with File History” option.


Step 3. Click the “Restore personal files” button.

If you want to change its saved path, right-click on “Restore” and select the “Restore to” option.
