I am very impressed with this simple, one-trick pony. Print Window is an excellent software product which searches a Finder window of your choice and delivers a report in the form of an Excel spreadsheet, a CSV (comma separated values) file, or a plain text file.
As every Mac user knows, the Finder presents information about every file in a Finder window in column headings that include: Name, Kind, Size, Version, Date Created, Date Modified, Comments, and Tag. In the process of issuing your command to Print Window, you get the opportunity along the way--via checkboxes--to select the File Information that you want Print Window to deliver. You can get all of those items, or you can get a custom set of only the items you want.
You can opt to have Print Window give you information on only the top layer of the Finder, or you can have it "expand all folders" automatically to give you Finder window details of all the sub-folders, too. Unless you specially indicate how many levels deep you want to go, Print Window will go through all of the sub-folders to the very basement. If you don't want Print Window to do this deep digging of all folders, you can opt to manually select those folders which you do want it to go to the depths.
Print Window matches this flexibility in gathering the data with an equally flexible set of reporting options.
For my particular needs in a project I gave myself regarding the gathering in one place of all the software applications installed on the five partitions of my hard drive (each one with a different Mac OS X version), together with information on all the applications installed in over two dozen volumes partitioned across five LaCie external Firewire hard drives, I preferred my reports to be in the form of Excel spreadsheets.
Print Window had absolutely no problem ferreting out the list of information contained in the Applications folder of each of those volumes. It also had no problems giving me nice, clean Excel spreadsheets to play with--one spreadsheet report per search. After adding a column to indicate on each sheet which volume had contributed its information, I then combined all of the spreadsheets into one master spreadsheet, and I imported that data in a FileMaker Pro data base that now lets me see at a glance what versions of each application is installed on volumes ranging from El Capitan to Panther, so that I can optimize the use of "legacy" apps without having to pay for expensive upgrades when individual apps and the Mac OS get out of step every so often.
Also, with disk utilities installed on every volume, I can run maintenance and repairs from any one volume on any other.
Thanks to Print Window, I now have a database of over 4,100 items featuring the software applications listed in the Finder's Applications folders on my many volumes.
I know of no other Mac program which uses a moderately simple User interface to deliver Finder information like that so quickly, so effortlessly, and so elegantly.
In terms of marketing, the developer invites you to find out for yourself how the program works: he grants you a 30-day free trial with no restrictions. You can't lose.
