Sometimes you need to attach large files. If these are too big TFS will tell you about it. [![SNAGHTML6bb62f9](https://blogs.incyclesoftware.com/hs-fs/file-3472674180-png/blog-files/snaghtml6bb62f9_thumb.png?width=244&height=109&name=snaghtml6bb62f9_thumb.png)](http://incycle-corpweb.azurewebsites.net/wp-content/uploads/2012/08/SNAGHTML6bb62f9.png) As suggested, you can put the file in Source Control and then link to it. However, if you really need to attach the file, you can increase the size limit for the attachments. Below you will find 2 methods you can use to accomplish this. **Method #1 – Web Service** 1. Navigate to http://localhost:8080/tfs//WorkItemTracking/v1.0/ ConfigurationSettingsService.asmx?op=SetMaxAttachmentSize 2. Enter the new value (in bytes, up to 2 GB) in the **maxSize** field 3. Click **Invoke** **Method #2 – C#** Programmatically, update the value directly in the TFS Registry. ``` /// <summary> ``` ``` /// Sets the maximum attachment size for the given server. ``` ``` /// </summary> ``` ``` /// <param name="tfsUrl">The TFS URL.</param> ``` ``` /// <param name="newAttachmentSize">The new maximum attachment size.</param> ``` ``` public void SetMaximumAttachmentSize(string tfsUrl, long newAttachmentSize) ``` ``` { ``` ``` var configServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(tfsUrl)); ``` ``` var rw = configServer.GetService<ITeamFoundationRegistry>(); ``` ``` var rc = rw.ReadEntries(@"/Service/WorkItemTracking/Settings/MaxAttachmentSize"); ``` ``` if (rc.Count > 0) ``` ``` { ``` ``` var re = rc.First(); ``` ``` re.Value = newAttachmentSize.ToString(CultureInfo.InvariantCulture); ``` ``` rw.WriteEntries(new List<RegistryEntry> { re }); ``` ``` } ``` ``` } ``` Topics: [Blog](https://blogs.incyclesoftware.com/topic/blog) --- ### Recent Posts By InCycle - 25 July, 2012 #### InCycle Wins Prestigious Microsoft Global Partner of the Year Award [![read more](https://cdn2.hubspot.net/hubfs/685080/IMG-TurboSodium/Sodium%20v2/blog/arrow-recent-blog-post.png "read more")](https://blogs.incyclesoftware.com/incycle-wins-prestigious-microsoft-global-partner-of-the-year-award) By InCycle - 25 July, 2012 #### Top 5 Questions On Elevate for App Modernization [![read more](https://cdn2.hubspot.net/hubfs/685080/IMG-TurboSodium/Sodium%20v2/blog/arrow-recent-blog-post.png "read more")](https://blogs.incyclesoftware.com/top-five-questions-on-elevate-for-app-modernization) By InCycle - 25 July, 2012 #### GitHub Universe 2025 Top Announcements [![read more](https://cdn2.hubspot.net/hubfs/685080/IMG-TurboSodium/Sodium%20v2/blog/arrow-recent-blog-post.png "read more")](https://blogs.incyclesoftware.com/github-universe-2025-top-announcements) --- ### Subscribe to Blog ### ![2025 Microsoft Partner of the Year Winner: InCycle Software](https://blogs.incyclesoftware.com/hs-fs/hubfs/InCycle%202025%20Microsoft%20PoY%20Badge.png?width=377&height=223&name=InCycle%202025%20Microsoft%20PoY%20Badge.png) ### About this blog Since 2002, InCycle has been providing challenging thought leadership to help customers successfully combine modern application designs, IT platforms and DevOps practices to achieve new levels of success.
