Deleting a file in the gallery removes the attachment from the work item. It is the same operation as deleting the attachment in Polarion’s own Attachments section.

​
Prerequisites

  • You have permission to modify the work item’s attachments

​
Delete a File

1

Find the file

Locate its tile in the gallery, in either grid or list view.
2

Select the delete control

Each tile carries a delete control alongside its download control.
3

Confirm

The browser asks you to confirm before anything is removed, naming the file it is about to delete.The name in that prompt is the attachment’s internal identifier, which carries a numeric prefix — a file you uploaded as notes.txt is named in the prompt as 5-notes.txt. That prefix is assigned by Polarion; it does not mean a different file.
The file disappears from the gallery as soon as you confirm. Polarion’s own Attachments section still lists it until you reload the work item — see Gallery and Attachments.
Deleting is not the way to replace a file.To put a newer version in place of an existing file, upload the new file under the same name — it replaces the content and keeps the earlier version in the attachment’s revision history. Deleting first loses that continuity. See Uploading Files.

Uploading Files

Add files, and replace one in place.
