Is It Safe to Change a Drive Letter in Windows?

Changing the drive letter is not entirely harmless and can cause significant problems based on the contents of your drive. If you have applications and software installed on your drive, those applications may cease to work.

For example, if you change the name of your D: drive to an F: drive, then the software installed in the D drive will still search for code in the D: file. While you can still access the data inside, there may be errors that will cause a nuisance in your day-to-day usage.

However, you may safely change the letter of some drives. If a partition simply includes data files that you rarely use, changing the drive letter may cause minor inconvenience, but nothing serious. The letters of external drives can almost always be changed without any problems.

1. How are drive letters assigned in Windows?

2. Can I change the drive letter for the System Drive?
