I have 10 files with extention (.csv). I need to read the timestamp of each file (unix timestamp) and save them in one column in text file. Any help is greatly appreciated

Do you mean the date of the last file access?

D         = dir('*.xls');
TimeStamp = {D.date};
% Or:
TimeStamp = [D.datenum];

Hi Jan I want to read the timestamp of 20 laser data (data.csv) and 20 images (image.jpg). I want to read the date and time of these files when they were taken and saved.

Do you mean the file creation date or the EXIF information in the JPEG file?

Hi Jan and thank you for your support. I mean the timestamp of the file creation . Could you please tell me what do you mean by the EXIF information in the JPEG file? your help is highly appreciated

[Jan]

You find an exhaustive description of the EXIF data by asking Google or searching at WikiPedia: It is the header of JPEG files, which is written by the camera and not influenced by any file operations on the processing computers (except for clearing the EXIF header, of course).

If you are working under Windows, you can use http://www.mathworks.com/matlabcentral/fileexchange/24671-filetime.

Hi Jan. Thanks again. Do you know how I can get the filename suffice?

What does "the filename suffice" mean?
