List of Unsupported Files

Some Connectors have a list of file names and types they will not accept as uploads and some Connectors will not allow certain files to be downloaded.

We skip these unsupported files automatically in a transfer and do not consider them failures. Therefore, a transfer that ran correctly, but did not transfer any of these unsupported files, will be considered a success.

For your reference, here's a list of unsupported file and filetypes that we can't download or upload from our various Connectors that will be marked as skipped in the transfer logs:
