RegEx: Can you rename a File with a part of the Parent Folder name?

Help & Support
1

In Advanced Rename, I'm trying to use RegEx to capture part of the Parent Name and append it to the Original File Name.

Old Name:
^.*\\(\[.*?\]).[^\[]+(\[.*\])\\.*
New Name:
\1 {name} \2

It seems to work on RegEx101.com:

Example Full Path:
X:\East\_Complete Downloads\[2ndfire]Haibane_Renmei[BD][1080p][Dual-Audio][AV1][10bit]\Haibane Renmei - S01E01 - Cocoon Dream of Falling from the Sky Old Home.mkv

Desired Result:
[2ndfire] Haibane Renmei - S01E01 - Cocoon Dream [BD][1080p][Dual-Audio][AV1][10bit].mkv

The regex is performed on the filename, not the full path, so that approach won't work.

You can use {parent1}, {parent2}, etc. to insert the names of parent folders into the new name. So you could do that and then a second rename. Or you could use a rename script which lets you do pretty much anything, all in one go, including apply a regex to the full path: Script to perform multiple Regular Expressions

What about this example? It looks like it's possible or am I wrong?

That's just using characters from the filename.

Okay, I see now. The first few numbers of the folder are also in the file so the RegEx just pulls them from the file.

Thanks!
