Title: finding files in a directory with a specific file mask

Hi Mark !

 

Here is a testprogram that lists all files in a current folder (and its subfolders) based on a certain mask.

I don't know what you want to do with the ini. -files, but perhaps you can use this structure to get started ?

 

Hope it helps...

�mne: [jdjlist] finding files in a directory with a specific file mask

hi everyone..

i am making the conversion from delphi to java.

i am writing my first java utility app that will

1) loop through a given directory (on a windows box) looking for files with a specific file mask

2) then open up the file and interrogate the information inside (the files are actually .ini files)

3) and then write out the information in an XML format

my first task at hand is item 1)

i have classes/components written in Delphi to do recursive file searching - but i don't have a clue as to how to do this in java.  any help, sources of information or guidance would be hugely appreciated.

any help or suggestions on items 2) and or 3) would also be appreciated.

thx
mark
