Foldnize reuses existing year and month folders. Missing folders are created only when required.

Build the archive safely

1. Select the highest-level folder you want Foldnize to scan.
2. Choose whether to rename files, or leave the renaming mode unchanged for your workflow.
3. Enable Sort into Year/Month folders.
4. Leave recursive scanning enabled if media is spread across nested folders.
5. Run a Dry run and inspect both the destination folder and filename.
6. Apply the operation after confirming the preview.

Year/Month sorting from the CLI

npx foldnize --root=./media --mode=prefix --year-month --dry-run

This keeps each original filename, adds the date prefix, and previews a move into the matching year and month. Remove --dry-run to apply.

Organize mixed photos and videos together

The same archive can contain JPG, PNG, MOV, MP4, and MP3 files. Images use EXIF-style original dates; supported videos can use QuickTime metadata or FFprobe output. A single trip’s photos and videos therefore land in the same chronological month.

What happens to existing folders?

• Files already in the correct folder can remain there.
• Already formatted filenames are not repeatedly renamed.
• Empty folders left after moves are preserved.
• Filename collisions receive numbered suffixes.
• Files without readable dates are skipped.
