Samurai Search
Search source code, plain text files and PDF files on your iOS device or in iCloud/USB/SMB, preview matched files, or open in your favourite editing/viewing app.
Supports flexible search options, including regular expressions (for plain text files). Files searched can be selected from standard or custom text file types.
Search files or folders can be selected from On My iPad, iCloud Drive or external file providers (e.g SMB/USB folder). Saved search files/folders are retained by the app where possible.
iCloud files in the selected iCloud Drive folders that match the file type (file extension) criteria, will be downloaded prior to searching.
Note: Some third party file providers don’t currently provide external folder access.
