File sharing in Teams is for collaboration only. Please do not use Teams or SharePoint for your main storage. Continue to use your H or W network drives. Teams/SharePoint storage is not backed up. If you delete a file in Teams/SharePoint, you only have 30 days to retrieve it from your recycle bin.
- To delete a file from a Teams channel, select the Team you want to remove the shared file on the left-side of Teams
- Select Files from the top banner. That will list the files in that specific Teams channel. Then select the three dots next to the file you want to remove and select Delete
