Illustrator 2026 (30.0) saved files contain a large amount of blank space.
OS: windows 21H2
Adobe Illustrator 2026 (30.0) (desktop) 
In Adobe Illustrator 2026 (version 30.0), files saved with default settings are significantly larger than those from the previous version. Before saving, the action “Delete Unused Panel Items” is executed to remove all unnecessary elements (the Save Options panel as Figure 1).
A comparison of file sizes with version 29 (with identical content, Figure 2) confirms this increase. When the file is opened as a text document (Figure 3), it reveals a substantial amount of whitespace.
