What directories can we save files to from a DataFlow?

[natecdavis]

Are there any directories we can save a file to from within a DataFlow other than the run directory specific to the current run?

[natecdavis]

The solution was to add network service permissions to the desired directory.

In Composable, files can be saved to any directory that the Composable instance has access to. This includes:

• The Run directory specific to the current DataFlow Run
• Any local drives on the server(s) hosting the Composable instance
• Any networked or shared drives that the Composable instance has permissions to access

File Handling Modules in Composable

Composable provides two sets of file-handling Modules:

1. Modules without "Credential" in their name

   • These Modules use the Composable instance's network service account to access directories.
   • If the network service account has read/write permissions to a directory, the Module will work without requiring additional credentials.
   • Note that these Modules are typically only accessible to the admins of the Composable instance.

2. Modules with "Credential" in their name

   • These Modules accept a Composable Key (username/password) to access a specific drive, network share, or folder.
   • This allows the DataFlow to access directories using credentials different from the Composable network service account.

Example Comparison

File Saver Module (Uses the network service account)

• Saves a file to a directory using the Composable network service account.
• Works if the network service account has the necessary permissions.

Inputs:

• File: The file to save
• DirectoryInput: Target directory
• FileName: New file name (optional)
• Overwrite: Whether to overwrite an existing file
• ReadOnly: Mark file as read-only
• PreserveModifiedTime: Preserve modified date/time

Outputs:

• Success: Indicates if the file was saved successfully
• FileNameOut: Name of saved file (may differ if sanitized)

Credential File Saver Module (Uses user-supplied credentials)

• Saves a file using supplied username/password credentials.
• Can access directories that the network service account might not have access to.

Inputs: (Same as File Saver, plus one extra field)

• Credentials: A Composable Key containing username/password for authentication

Outputs: (Same as File Saver)

By choosing the appropriate Module, you can control whether to rely on the network service account's permissions or use specific credentials for accessing files.
