What is the max file size that TM supports? TextEdit is able to open 267MB file and working smoothly.

It works smoothly? Not my experience ;)

However I got an "Out of Memory" error. There are 3.9GB free memory in the system.

Despite the amount of system memory, a single application normally can’t get more than around a giga-byte, and because of all the parsing TextMate does (assign scopes to things), internally using UTF-16, etc. it will generally require probably 8 times the file size. There is no exact limit, but probably ~150-200 MB is a good estimate.

On a related note though, TextMate is _not_ designed to work with large files.
