Since Tabbles 5.2.31, you can use regular expressions within the auto-tagging rules to tag files based on their name, path and content.
Contents
What are the regular expressions and how do they work?
- Regex on wikipedia
- Page on Codeplex
- Online regular expression editors RegExr and regex101
- Download Expresso, a regular expression editor
- The reference page on MSDN
- Regular expression library (warning: the syntax could be different... the one on the MSDN page is the one that should work)
Do I have to write them myself?
You will hardly need to write any regex yourself, because there are a multitude of regex that have been written and tested out there. Your best chance is to simply google "regex {whatever I need}" and see what comes up. Below a few useful resources:
- European personal data regexp patterns
- Searchable Collection of regex RegExLib
How do I use them in Tabbles?
Go to: Tools > Auto-tagging rules > New and edit the window to something like this:
From now on, whenever you create/save/rename a file/folder that matches tha regular expression, the file will be tagged (and a one-click pop-up should come up too).
If you want to automatically tag the files you already have, you need to use the function Tools > Run rules now. In order to use this function you need to first select a folder/disk within Tabbles.
Pocket size tutorial
Let's analyze a working regular expression:
.*\.avi$|.*\.mov$|.*\.mpg$ This one matches .avi OR .mov OR .mpg. A little explanation:
.* = matches any character
\. = matches the character "." (the dot)
avi = matches the pattern "avi" (and also mov and mpg)
^ = beginning of the pattern to be matched (put this in the beginning of the thing you want to match)
$ = end of the pattern to be matched (append this at the end of the thing you want to match)
| = plain and simple logical OR
So, if you want to add another extension, like .mp3, you append |.*\.mp3$ to the previous expression.
Other interesting stuff:
\b = matches backslash, ^ = beginning of the line to be matched, the opposite of $
Well, the rest is in the msdn reference...
Library of working regular expressions
This is a list of working regular expression: to contribute or request new ones, post in the forum thread :-)

| .*\.avi$|.*\.mov$|.*\.mpg$ | matches .avi OR .mov OR .mpg | Andrea |
| .*England.*|.*Great.*Britain|.*United.*Kingdom.*|.*Northern.*Ireland|.*Wales.*|.*Scotland.* | matches "Great Britain", "Great_Britain", "Great-Britain" (along with the rest of the UK) etc. | Andrea |
| .*(201\d).* | matches 2010 to 2019 (useful for years). Change "201" to "200" to match 2000 to 2009 | Andrea |
| ((67\d{2})|(4\d{3})|(5[1-5]\d{2})|(6011))(-?\s?\d{4}){3}|(3[4,7])\d{2}-?\s?\d{6}-?\s?\d{5} | Credit cards (works with the major cards, with "-" or without) | Andrea |
| .*C\d{3}.* | Matches files with a path like "D:\Customers\C001" to "C999" or "...\stuff_C001_stuff" (to ...C999) | Andrea |

Hint: be careful with the dots and the crazy characters - dont' lose half of them while copy-pasting!
