Find in Files

You can search the contents of all text files in the current folder and its subfolders for matching text or regular expressions.

Tap the search field above a file listing and change the search mode from Filename to Content.

Searching file content


Tap the Search Settings button (“gear” icon) to open the file content search settings screen.

Search settings button

Here you can choose whether to match text or a regular expression. You can also specify whether the search should be case sensitive, diacritic sensitive, and whether to search for whole words only:

Search settings

Search for a simple text string. You can also search for “\n” or “\r” to find newline characters and “\t” to find tab characters. Enter “\\” to search for a backslash.

Regular Expression

Enable regular expression search. Textastic uses the ICU regular expression syntax.

Case Sensitive

By default, search is case-insensitive. Enable this setting to make search case sensitive and only find instances with matching case.

Diacritic Sensitive

By default, search ignores diacritic marks: for example, ‘ö’ is equal to ‘o’ and ‘é’ is equal to ‘e’. Enable this setting to only find letters with matching diacritic marks.


this setting is not shown when using regular expression search. Regular expression search is always diacritic sensitive.

Whole Words

If you enable this setting, the search will only find whole words. For example, a search for “word” will find “word” but not “wording” or “password”.
