In every Delimiter Data Reader that I’m using for reading flat files i’m getting endless loop. For ex. I have flat file with 30 rows, but on output it gives milions of rows!

Try to use UniversalDataReader - that is a successor to DelimitedDataReader which is able to handle more problems in imput data. Could you send/post also the .grf file which is causing the problem ? Nonetheless, your problem is quite odd. We have not seen this behavior before with this component. ---

Same story with Universal Data Reader. Graph: [http://www.sendspace.com/file/lcfs8w](http://www.sendspace.com/file/lcfs8w) ---

This is for sure environment problem (probably eclipse). 1/10 times graph works fine. ---

Furthermore, the output file includes only those values, which are Autofilling. Non of the “in file” data is proceeded to output. ---

I checked up your graph file and I didn’t find a metadata file. I suppose you have autofilling for all metadata. Ie: Then you are right. The clover should throw an exception because there isn’t a metadata description how to read the data. ---

If you want to get only file name I suppose to use SystemExecute component. Something like dir -… \> fileNames.txt and then use a reader.
