I have got around 100 files. I would like to concatenate them into a single file. Just a note, these are all text files and there should not be any spaces in between file1 and file2 or file2 and file3 and so on. Also, contents of the file2, file3 and so on will start from the next line wherever the previous file end. For example,

file_20140801_1

100        20140101
101        20140102

file_20140802_2

1000     20130101
1001     20130102

file_20140803_3

2000    20140601
2001    20140602


When I concatenate above three files, it should look like below,

file

100        20140101
101        20140102
1000      20130101
1001      20130102
2000      20140601
2001      20140602

Considering above example, how do I concatenate around 100 files into a single file in UNIX. Please advise.
