While doing this process am failing at create file step due to already target folder having the file with same name. Here my task is if already exists with same name need to override that existing file with new one else paste the new one.

Error :

A file with the name Shared Documents/CPG Dashboard/Original PBIX/PBIx developed by BPO/DS Project - EVM All Items_test.csv already exists. It was last modified by i:0#.f|membership|rd9879@zebra.com on 11 Jun 2026 09:46:25 -0700.

Using flows

Hi @RD-11061850-0

The fastest way to enable file overwriting is to disable "Allow Chunking" in the Create File action settings.

In the Settings under Content transfer toggle OFF Allow chunking.

This approach works only for files under approximately 100 MB (the exact threshold varies between 70-100 MB depending on encoding). If your file is too large, the flow will report an error when chunking is disabled.
