using to check if a file exists by using os.path or pathlib module does physically check if the file exists. that is ok - no doubts.

- file not found *
- no such directory *
- file in use or blocked
- no permission to access
- bad file descriptor: using wrong mode
- no space left on the device
- file is read-only
- resource temporarily unavailable
- network dropped connection
- connection timed out
- connection refused
- input/output error
