SFTP Exists

SFTP Exists

Type: sftp-exists  ·  Package: SFTP Activities v1.1.0  ·  Output: bool

Checks whether a file or folder exists on the server and returns true/false. Useful to wait for a file to show up before downloading it, or to avoid overwriting an existing one.

How it works

Looks up remotePath on the server. It returns true whether it is a file or a folder, and false if it does not exist: it does not fail because of a missing path. It changes nothing on the server.

Required parameters

Parameter	Type	Default	Description
remotePath	string	—	Remote path to check (file or folder).

Optional parameters

Parameter	Type	Default	Description
session	ZoanSftpSession	—	Session from SFTP Connect. Inherited inside a body.

Output

Returns a bool: true if the path exists (file or folder), false otherwise.

Common errors

Message	Cause and fix
'remotePath' is required.	The parameter is missing or the expression returned null.
'session' must be a ZoanSftpSession.	The activity is outside the SFTP Connect body and received no session.
Server error: permission denied	The user cannot query the folder that contains the path.

Example

Create the month folder only if it is missing, and download the report if it is already there:

SFTP Exists   remotePath = "/inbound/" + today().ToString("yyyy-MM")   → output: hasFolder
If   condition = !hasFolder
 └─ then:
      SFTP Create Directory   remotePath = "/inbound/" + today().ToString("yyyy-MM")

SFTP Exists   remotePath = "/outbound/report.csv"   → output: hasReport
If   condition = hasReport
 └─ then:
      SFTP Download   remotePath = "/outbound/report.csv"   localPath = "C:/downloads/report.csv"
