Can the drive letters from the C and D drives be switched.

[fmagistro]

My computer has a 256 GB SSDrive and a 2TB hard drive.  The 256 GB is designated as the C Drive and the 2TB hard drive is designated as the D Drive.  The problem is that the smaller C Drive keeps filling and I have to clean it virtually every other day to be able to keep operating.  Is there some way I can copy all of C Drive to the D Drive and then change the designation of the D Drive to the C Drive.  This would solve my problem and I would designate the current C Drive as the D Drive and save it for special projects.  Is this possible?

You have to rebuild your machine to be able to switch but WHY switching OS and apps/programs to slower drive. The reason C: is filling up because you store many things on C:. You have to tell your machine to use 😧 as default drive to store all users files/data and ONLY use C: for OS and apps/programs.

Please

(a) Use the following way to tell your machine to use 😧 as default for your files/data

(b) Now move all your data/files to 😧 and change Save as location from Apps/programs
