Hi,

 

 

Using FME I want to copy a set of files in 1 directory to a different and then add a new file extension (whilst retaining the old).

 

 

I have created a workflow which works by reading all files within a directory, I then use the AttributeExposer, FilenamePartExtractor and StringConcatenator to obtain the details of existing filename and also create the new name. I then use a fanout on the text writer to output to the new directory. The problem is that I think it is inefficient as the contents of the files are being read in and then processed, when this only needs to be completed at file level and not contents level.

 

 

The input files are essentially text files from a mainframe, and named as user id and mainframe report output number, i.e.

 

 

asd0122.012

 

asd0122.013

 

asd0122.014

 

 

I am keen to retain the existing 'extension' as this provide information of report request order and therefore want to produce the following

 

 

asd0122.012.txt

 

asd0122.013.txt

 

asd0122.014.txt

 

 

I imagine that python script could be used to do this, could any one help? (Typically I know how to rename using ms dos, but do not know if I can 'call' or run an ms dos command within FME.)

 

 

 

The source and destination locations are known and will not change (or perhaps parameters could be used to add extra longevity to the process?).

 

 

(Source) e.g. C:\\project\\abc\\data\\input

 

(Destination) e.g. C:\\project\\abc\\data\\intermediate\\01\\01

 

 

 

Any help or advice would be appreciated,

 

 

 

I am using 2013sp1 build 13448

Hi Rob,

 

 

I think that

 

Directory and File Pathnames Reader ePATH],

 

StrindConcatenator,

 

AttributeRenamer,

 

and File Copy Writer rFILECOPY] can do that efficiently.

 

 

Takashi
Many thanks for the responses, I have successfully configured the workbench to rename copied version of the files as needed.

 

 

Takashi, I found the file_copy_dest_filename in the filecopy writer which was required following the filename extartion and string concatenation elements. This was part which had previously stumped me; I suspected that this feature must have existed.

 

 

Gio, thanks also for the referencing the Google post, this will also prove to be a useful technique.

 

 

Regards,

 

 

Rob
