Which files open?
Android · iPhone · quillo.trUpdated:
PDF, Word (.docx), ODT, EPUB, image files (JPEG, PNG) and any file that contains text: plain text (.txt), Markdown (.md), logs (.log), LaTeX; data files (.csv, .tsv, .json, .xml, .yaml, .toml, .ini, .env, .properties); web files (.html, .css, .js, .ts, .svg); code files (.py, .java, .kt, .swift, .c, .cpp, .cs, .go, .rs, .php, .rb, .dart, .sql, .sh, .bat, .ps1, .gradle…) and subtitles (.srt, .vtt, .ass). Text files are turned into readable pages; the source text is kept and can be edited with "Edit text". If Turkish characters look garbled, the file uses an old encoding; tries Windows-1254 automatically.
Old binary .doc files aren't supported; save them as .docx in Word and try again. Password-protected PDFs ask for the password when they open.
Each source shows with a badge in the library: PDF, Text, Photo, Word, Web, EPUB, Scan. The library can be filtered by these badges.
