On My Windows drive I was trying to determine why my disk space is rapidly dropping, when I haven't been installing any new applications.
I found that in my Acrobat folder in the ProgramData folder are three folders 9.0, 9.2 and 9.4. In the 9.2 folder there are 700mb of .MSP files, and in the 9.4 folder there are almost 300 of .MSP files. They appear to be related to ARM?
Are these files left over from updates? can I delete them?
These files are used to update your installed version of Acrobat to the latest version.
If the latest version of your Acrobat installation is not 9.5.0 (See Help->About Adobe Acrobat), I suggest you update it to the latest stable and secure version from "Help->Check for Updates..." option.
Meanwhile you can delete the 9.2 folder and once your acrobat gets updated, the 9.4 folder will automatically get deleted.
