File type from file name

[Former Member]

Hi,

Is there any standard method to get a file type from file name?

File name can be ‘C:\test.doc’ or “C:\test’(test – is file) i.e. with or without file type extension.

hi Naddy,

I think you can adopt the following logic:

check if the file name contains dot.

if yes split the file name at the dot into an internal table

the last line of the internal table will contain the extension

something like:

IF filename CA '.'.

SPLIT filename AT '.' INTO itab.

read last line of itab...

ENDIF.

hope this helps

Why we need to put into internal table?

Is string variable not enough?

what if file name without extension i.e. '.'?

"Why we need to put into internal table?"

just to be sure, when there are more dots in the filename (for example: C:\temp\te.mp\test.doc, in this case there will be three lines (because of the SPLIT AT '.')

"what if file name without extension i.e. '.'?"

then there will be an empty line in your interna table (as last line)

what if file name is 'C:\temp\te.mp\test'?

[JozsefSzikszai]

you are right...

than I would suggest to do in two steps:

first SPLIT AT '\'

Than take the last line and if it contains a dot, than SPLIT AT '.'

I'll try your method.

what is the line type 'Internal Table'?

You can use the Function module PC_SPLIT_COMPLETE_FILENAME

export paramter extension will tell the type of file

Sample Output

Import	COMPLETE_FILENAME	C:\TEST.TXT
Import	CHECK_DOS_FORMAT	
Export	DRIVE	C
Export	EXTENSION	TXT
Export	NAME	TEST
Export	NAME_WITH_EXT	TEST.TXT
Export	PATH	\
