What is mso cache?

MSO cache stands for Microsoft Office cache. It is a folder located on your Windows computer where Microsoft Office products store temporary files to speed up their performance. These files are created when you open a document or file in Microsoft Office and are used to speed up the opening and saving of files. MSO cache is created automatically by Microsoft Office and can be located in different folders depending on the version of Microsoft Office you are using. It is generally safe to delete these files, as they will be automatically recreated as needed. However, it is recommended to clear your MSO cache periodically to free up disk space and improve the performance of Microsoft Office. You can do this by going into the Office Upload Center and selecting "Delete cache files".
