Attachment file format in the backend of jira

[Rajesh Ramankutty]

Hi guys,

Can anyone tell me what is the file formate jira will store the attachment in the backend server if we upload any file in the jira core or soft.

Binary.  Jira stores the file exactly as it receives it from the users.  (Unless you use an app to encypt at rest, which I'd always recommend)

Hi @Nic Brough -Adaptavist- 

this is wat am asking how to make this file in the backend as same as in the font end like how we are uploading it.

[Nic Brough -Adaptavist-]

You don't.  The file is already stored as the binary the person gave it, the format has not changed (which is what you asked about). 

But the file will have a new name that Jira handles versions and file location with.

I strongly recommend that you stop looking at the file system - you must not change it outside Jira and you're not going to have much fun reading it, so don't bother.

Try using the REST API to look at attachments instead.

Hi Nic,

Thats a good point to not look at the file system.

One doubt: If we have a need of migrating to other systems from Jira, how do we extract these attachments in the original format(since jira changed it to binary and maintaining with new names/versions).

Say that my user wants to move his Project from Jira to AzureDevops or etcc.
As a Jira-Admin I have shared the issue export in csv and how do I share the attachments in original format?

Again, Jira has NOT changed the format of the file.  It has stored exactly the same binary that the user gave it.

To extract the files, read Jira over the REST API.

Hi @Rajesh Ramankutty ,

Looks like file without extension. Below attachment png picture.
