Hi @rogerg42202737 

Thanks for reaching out.

Are you referring to the windows temp files? The path for it is Windows +R/ Run window>%Temp% 

Is that how you are deleting the temp files?

If yes, open Task Manager > Processes> select all the Acrobat processes running in the background and > End Task. 

The processes running in the background probably do not let you delete its temp file because it's already in use.

Once closed the task, try deleting the temp files again.

Thanks,

Akanchha
