How to read a set of Time files of a simulation containing any number of digits after decimal point

I have a set of time files from a simulation. For eg 2.1005, 2.1015, 2.16987, 2.305, 2.5 and so on. I have a code, but it can read only those "time files" that contain 4 digits after the decimal point; i.e., it can read 2.1005, 2.1015 and then stops. It can't read 2.16987 or 2.305 or 2.5.

Can anyone help me how to read time file that contain any number of digits after the decimal point.
