JetBrains Rider 2024.1 Help

Configure file size limits

File size limits in IDE properties

For performance and memory consumption reasons, JetBrains Rider sets the following file size limits:

  • The maximum size for files that JetBrains Rider is able to open, is controlled by the idea.max.content.load.filesize IDE property. The default value is 20000 kilobytes.

  • The maximum size for files where JetBrains Rider enables coding assistance and design-time code inspection, is controlled by the idea.max.intellisense.filesize property. The default value is 2500 kilobytes.

Change the file size limits in IDE properties

  1. Do one of the following:

    • Select Help | Edit Custom Properties from the main menu.

    • On the Welcome screen, click Configure and then select Edit Custom Properties.

    • If you cannot start JetBrains Rider, you can manually create an empty file in the JetBrains Rider configuration directory.

  2. In the custom file that opens in a new editor tab, specify the desired values in kilobytes, for example:


    The properties you add to this file override the corresponding default properties.

File size limit for design-time inspection

JetBrains Rider additionally limits the size of files where design-time inspection is enabled by default to 300 kilobytes. For larger files, the inspection is disabled to make sure such files load without delays. You can recognize files where code inspection is disabled by the OFF indicator in the top right corner of the editor.

You can press Ctrl+Alt+Shift+8 to enable inspection in the file as long as its size doesn't exceed the limit specified by the idea.max.intellisense.filesize property. JetBrains Rider will remember your choice and will not disable design-time inspection next time you open that file.
