importing other contract in remix gone wrong despite write file name or path [closed]

Question

 import "./filename.sol"

output Error: not found SimpleStorage.sol

Answer 1

Without the folder and file structures, exact names of the contracts, it is hard to find the issue. Anyway you can try these,

1. Try using absolute file path instead of the relative file path. (Anyway the relative path also should work fine)
2. Check the contract names as it is case-sensitive.
