+# Project Import Decompressed Archive Size Limits
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/31564) in GitLab 13.2.
+
+When using [Project Import](../user/project/settings/import_export.md), the size of the decompressed project archive is limited to 10Gb.
+
+If decompressed size exceeds this limit, `Decompressed archive size validation failed` error is returned.
+
+## Enable/disable size validation
+
+Decompressed size validation is enabled by default.
+If you have a project with decompressed size exceeding this limit,
+it is possible to disable the validation by turning off the
+`validate_import_decompressed_archive_size` feature flag.
+
+Start a [Rails console](../administration/troubleshooting/debug.md#starting-a-rails-console-session).
+
+```ruby
+# Disable
+Feature.disable(:validate_import_decompressed_archive_size)
+
+# Enable
+Feature.enable(:validate_import_decompressed_archive_size)
