I'm using Igor on both winXP and win7. Sometimes I transfer projects from winXP to win7. My projects includes lots of data files. I would like to import the data into .pxp file w/o changing anything on the source files. However, the loading process will change the file's Date Modified. Could anyone tell me how to avoid it?

I use loadwave like this: LoadWave/Q/D/O/P=filePath fileName

Weird thing is that it was not doing that at the beginning. I don't quite remember when it started doing this.
LoadWave opens the file for read-only. It does not write to the file. I can't think of any reason why it would change the modification date.

I just tested Data->Load Waves->Load Waves (Load Delimited Text) under Windows 7 and I don't see any modification date change.

Reading the file will change the "last access" date on Windows. This is done automatically by the OS.

I see that when you copy a file under Windows 7, the creation date is set to the date of the copy while the modification date remains unchanged from the original.

Thank you for your reply.
I have not observed what exact condition makes the files Modified date change. What I have seen is that things are a little bit random. I will pay more attention to this issue later on. I just want to see if anybody encountered the same issue with me.
