Check Paths

Check whether a file exists

Python example:

exists = sandbox.files.exists("/tmp/result.json")

if not exists:
    sandbox.files.write("/tmp/result.json", "{}")

TypeScript example:

const exists = await sandbox.files.exists("/tmp/result.json");

if (!exists) {
  await sandbox.files.write("/tmp/result.json", "{}");
}

Get path information

Python example:

info = sandbox.files.get_info("/tmp/result.json")

print(info.name)
print(info.type)
print(info.path)

TypeScript example:

const info = await sandbox.files.getInfo("/tmp/result.json");

console.log(info.name);
console.log(info.type);
console.log(info.path);

Recommendations

exists() only tells you whether the path existed at the moment of the check. Concurrent tasks may modify files afterward, so critical writes still need idempotency and error handling on the application side.
