Introduction
We received a number of enquiries asking for migration pathway from Attachment Checker for Jira Data Center to File Type Checker for Jira Cloud.
File Type Checker is designed with Atlassian Cloud in mind, as well as tapping in our (many years of) experiences from Attachment Checker. It is not a ported edition of Attachment Checker and the features are not identical. That is also why the 2 apps have different names.
Comparison Matrix
-
Attachment Checker is the full attachment governance toolkit for Jira Data Center.
-
File Type Checker focuses on the file type security and reporting for attachments in Jira Cloud. For compliance, the Attachment Report and Searcher actually give better oversight than many Data Center setups.
Some of the key features
|
Feature |
File Type Checker
|
Attachment Checker
|
|---|---|---|
|
File-type enforcement |
Post-uploads checks: Performs the check to warn/quarantine/delete the unwanted files after the file has been uploaded. Feedback is provided via comments. |
Pre-upload checks: Blocks the unwanted files interactively with a warning message at the point of upload. Also handle attachments from emails. |
|
MIME Type Scanning |
Checks against the specified file extensions. This is the closest equivalent to Attachment Checker. |
Performs MIME type checks to prevent malicious uploads with renamed file extensions |
|
Searching for Attachments |
Attachment Searcher allows users to search attachments without digging into each work items |
|
|
Bulk Attachment Downloads |
Allows users to bulk download attachments |
|
|
Reports |
Provide various reports at space level |
The info can be easily queried from the database |
|
Missing Attachments |
Cloud does not allows long running jobs
|
Performs a deep scan on all the attachments to check if they can be found. Sometimes attachments may not be uploaded successfully or deleted from the backend. |
|
Large Attachments |
|
Useful tool for checking if performance issues are triggered by large attachments uploads |
|
Antivirus Scanning |
This will require copying the files to external servers (egress) which risks data leak |
Integrates with command-line AV scanners to scan uploaded files |
|
Disk Usage Quota |
Due to rate limiting controls on Atlassian Cloud |
Allows admins to set disk space quota at project level to prevent excessive disk usage |
|
Access Control |
|
Separates download attachment permission from browse issue permission. This can grant certain users from browsing the issue but prevent them from downloading attachments on the issue |
|
Download Logging |
No API available for attachment download event |
Can keep records on who downloaded the attachments |
|
Compatibility with 3rd party apps |
Cloud apps are microservices on different servers. Due to security concerns, they cannot allow access by 3rd party apps. |
Supports attachments for Assets, Xray, Zephyr Scale |
Migration Pathway
Since both apps are not exactly the same, there is no migration pathway.
For the file type checking, the list of file extensions can be copied over to the File Type Checker configuration page.
Conclusion
On Jira Data Center, Attachment Checker is a comprehensive attachment security and governance toolkit: it controls file types (by extension and MIME), integrates with your own antivirus, enforces limits (size, count, duplicates), and can even restrict who may download attachments.
On Jira Cloud, File Type Checker focuses on the parts that are feasible and most valuable in the Cloud environment: file type checking on upload, flexible handling of unwanted files (keep/quarantine/delete) with clear user notifications, plus powerful project‑level attachment reporting and search (Attachment Report and Attachment Searcher). It does not replicate on‑prem antivirus integration, per‑download access restrictions, or all the per‑issue volume limits from Data Center, but it gives Cloud‑native visibility and governance over which file types are stored where and by whom.
