External SSD is very slow in opening files
I just got a Crucial External SSD with Catalina OS. The apps open so fast, however, files from folders take forever to open. What could go wrong? Please help
iMac 21.5″, macOS 10.15

Welcome!
Hmmm, we have little to go on. Details are everything.
- What model Crucial?
- Have you confirmed that the external is set as a boot volume? Ways to start up your Mac - Apple Support (start while holding OPTION). If the SSD does not show in the resulting Startup Manager, the drive is not bootable.
- Did you CLONE the old drive to the external or did you COPY it? They are very different. If copied, it is unlikely to be bootable.
