Combine Download IF URL Conditions with AND/OR Logic

When one condition isn’t enough

A single Contains or Not Contains rule handles simple lists, but real scrapes are messier than that. You might want images from a specific path and only certain file extensions, or links from either of two folders. That is where the multi-condition side of Download IF URL in Bulk Image Downloader From URL List comes in: you can stack several conditions on a task and connect them with logic.

Building multiple condition rows

After enabling Download IF URL on a task, you start with one condition. To add more, use the + control — it adds another condition row, and you can keep adding as many rows as the job needs. Each row is a complete condition with its own type (Contains, Not Contains, or Regex) and its own text or pattern.

If you overbuild, the × control removes a row. Adding and removing rows is the everyday work of shaping a filter: start broad, add a row to tighten it, drop a row that turned out unnecessary. The keyword builder lives per task, so each task carries exactly the conditions it needs and nothing more.

AND versus OR

The logic connecting your rows is what makes multiple conditions powerful. There are two modes, and the difference is simple but important:

• AND — every condition must match for a URL to download. Use it to narrow: the more AND rows you add, the more specific and exclusive the filter becomes.
• OR — any single condition matching is enough. Use it to widen: a URL gets through if it satisfies even one of the rows.

A helpful way to remember it: AND tightens the net, OR widens it. If you are getting too many URLs through, you usually want AND and another condition. If you are getting too few, OR is often the fix.

Putting logic to work

Picture a scraped list that mixes product shots, icons, and widget graphics. You want full-size product images only. With AND, you might require the URL to contain “/products/” and not contain “thumb” — both conditions must hold, so only the large product files survive. Now suppose the site stores products under two different paths. Switch to OR and add a row for each path — a URL matching either one gets downloaded, catching both groups in a single run.

Because each URL is tested at download time, anything that fails your combined logic is simply skipped — it is not downloaded and not logged as a failure. Your original list stays intact the whole time, so you are free to retune the conditions and run again without rebuilding anything.

Dialing it in

The practical rhythm is to start with one condition, run or review, then add rows and pick AND or OR based on what is slipping through. Add a row to exclude junk, switch to OR to capture a second valid pattern, remove a row that overshot. Combined with the Contains, Not Contains, and Regex types, AND/OR logic lets you express precise intent — “these and not those, or also these” — against even a chaotic list, all without editing a single URL by hand.
