Examples

For each rule, enter a regex pattern to match against files in the source folder, and a regex template to use while naming the files created in the destination folder.

Patterns

The pattern must match the entire file name (along with its extension). Here are some examples:

Target one specific file

trackbook-backup\.zip

Important

Escape special characters, like periods and parentheses.

Target files starting a certain string and having a certain extension

AntennaPodBackup(.*)\.db

Caution

Ensure that the prefix is specific enough. Too-broad patterns may lead to data loss.

Target files while extracting information to be used in the template (see below)

TubularData-(?<date>\d{8})_(?<time>\d{6})\.zip

Templates

The template can contain references to groups captured in the pattern. Prefer named groups to avoid ambiguity. Here are some examples:

Static template

antennapod.db

Important

If a file with the same name is already present in the destination and the "overwrite existing" option has not been turned on, the flow will fail.

Dynamic template (named references)

tubular${date}.zip

Dynamic template (indexed references)

tubular$1.zip

Use these examples to build your own pattern/template pairs. You can visit regexr.com to learn more about regex, as well as build & test patterns. For advanced usage, you can use this playground to test against the actual Kotlin regex engine.
