Deleting All Files In A Folder Containing Specific Text

[ace5150]

my sequence reads and then deletes a txt file from a folder on our network. If the .txt file is written again, before DF has a chance to delete it, a second file is created in the folder.

 

Ex.

test.txt

test0.txt

test1.txt

......

............

test85.txt.

 

Is it possible to delete all "instances" of this file from a sequence in DaqFactory?

 

something along the lines of

File.Delete("C:\Users\Scott\Documents\test*.txt")

 

or would I have to do each individually:

File.Delete("C:\Users\Scott\Documents\test.txt")

File.Delete("C:\Users\Scott\Documents\test0.txt")

..................

................................................

File.Delete("C:\Users\Scott\Documents\test85.txt")

Use the getfilepathList() function to get a list of matching files, then cycle through and delete them.  Basically:

 

private string list = file.getFilePathList("c:\Users\Scott\Documents\test*.txt")

for (private i = 0, i < numrows(list), i++)

   file.delete(list)

endfor

 

I'm not sure delete() will take wildcards, but you can try it.  GetFilePathList() certainly does.

Unfortunately, that did not work. Delete() will not accept wildcards.Does anyone have any other suggestions?

Sorry, there was a typo in my script.  I do these snippets off the cuff, partially in hopes of teaching our customers how to do basic debugging.  Anyhow, list needs to be declared as a string.  I've edited my original post and tested it to verify it is correct.  

 

To debug that, I just added a ? list just before the delete() function call to see why I was getting the F0002, file not found error.  That printed NaN, which tells me that it tried to convert to a number and immediately told me my problem.

Thank You very much Guru, that did the trick.
