Workato SFTP connector: how to disable multipart uploads?

[eranarigiil]

Hi

We are using the SFTP connector via OPA.

We are trying to upload a 25MB file to an SFTP site. The site does not support the multi part option: uploading smaller temp files and then renaming them.  The error we get: permission denied. Uploading smaller files works correctly.

If we use WinCSP the following works when we set:

disable transfer/resume to temporary filename

We tried to add to the SFTP connector in Workato:

useTempFile=false

resumeSupport=false

This didn't work.

How can we achieve it in Workato? (increasing the file chunk more than 20MB or disabling the automatic multipart upload)

Thanks

Hi @eranarigiil ,

In the first approach, the file can be divided into smaller chunks within the recipe (for example, 5 MB each) and uploaded sequentially to the target SFTP location. Once all parts are uploaded, a rejoin or merge script can be executed on the target system to reconstruct the original file. After successful reassembly, the temporary chunk files can be deleted to free up space.
In the second approach, the complete file can first be uploaded to Workato file storage, then compressed to reduce its size before being transferred to the SFTP destination. After confirming a successful upload, the compressed file should be deleted from Workato file storage to maintain efficiency. Both approaches can be executed entirely at runtime within the same recipe, ensuring end-to-end automation.

for the 3rd Approach, May be you can use this "File Tools by Workato" and "Compress Files" action and see if this works.
