Update May 2017

A May 2017 Microsft security update for Windows 10 conflicted with a major routine in FileBoss resulting in FileBoss not starting on some Windows 10 systems.

Versions V3.101 and later, fix the problem. You can read more about this at the page
Windows Creators Conflict.


Some of The Many Uses
of FileBoss

Here are just a few of the problems FileBoss solves for others with its rich set of powerful tools for manipulating files and folders. 

Replicate a directory structure

How to duplicate the structure of a path without actually copying any files. This was the problem of a graphic artist who needed a new, empty, folder structure for each new project.

See the Solution

Set filenames to lower case

A webmaster had to move several sites from a Windows based server to Linux. In the process she wanted to reduce all filenames to lower case to reduce problems with Linux's case-sensitive conventions.

See the Solution

Distribute one or more files to many folders

A server administrator needed to update a group of files and distribute them to over fifty different folders.

He was able to use FileBoss' distribute routine to 'Paste' the files into all fifty folders with just a couple of clicks of his mouse.

Organize Photos

A wedding photographer wanted to be able to upload hundreds of photos of a days work and quickly evaluate, rotate, sort and rename promising photos and delete the bad photos.

See the Solution

Change file extensions from htm to html across many folders

A webmaster needed to quickly change more than 100 files (located in various folders) named index.htm to index.html to conform to new corporate standards.

He used FileBoss to change their extensions using the Quick Set panel of FileBoss' rename facility. It took less than a minute!

Compare the 'System32' folders on two different computers

A systems developer was having problems installing software on one computer that appeared to be the same as another computer on which the software was already installed. In researching the problem they needed to compare the files in the system folder of both machines.

Using FileBoss's compare mode seeing the differences and similarities between the two folders was a quick, easy and thorough.

Copy a large number of files correcting errors on the fly

A trade magazine editor routinely copied and moved a number for documents around as they were being readied for publication each month.

Frequently though, Windows Explorer would abort the copy process because one file was in use or had been left locked by another program.

 The editor turned to FileBoss's sophisticated copy routines.

Refresh backup files

A programmer wanted to refresh his backup files of a work in progress to a server. Since some of the files were quite large she only wanted to copy files that had changed. And she didn't want to copy any of the hundreds of temporary files her compiler created.

See the Solution

Find a recently saved file without knowing its name

At the end of a very long day the head of The Utility Factory hit the 'Save As' button for a new document he had created and then, only after exiting the program, realized he didn't have any idea where the document had been stored or even what its name was.

See the Solution

Quickly free-up HD space for an emergency project

When a video services consultant needed more space in a hurry for a new client, he used FileBoss and File Sets to view and delete files.

See the Solution

Find and rename filenames too long to be included on a CD

While attempting to store a a collection of photographs the CD Burning software kept stopping because the length of a number of filenames (including their paths) were too long for the file system used by the CD.

See the Solution

Collect files from many folders into one

The Utility Factory (makers of FileBoss) bought several graphic collections to use as a basis for the toolbar buttons.

But one set was supplied where each button type was in its own folder based on file format, size and then use. FileBoss was able to copy them all to one folder quickly and easily.

See the Solution

Make duplicates of selected files within a folder

A graphic artist wanted to make temporary backup copies of a few files before he tweaked them with his favorite graphics program.

He selected the files in FileBoss' Explore view and used the Duplicate Action to make in-place copies of the files. Each file had a sequence number added so he could easily tell multiple generations apart.

See the Solution

Convert all spaces in filenames to underscores

A client required that all files supplied to them by contractor use dashes instead of spaces in their filenames.

The contractor used FileBoss to quickly create a File Set of all the files (across multiple folders) that would be sent to the client and then used the Quick Sets panel of the rename routine to convert all the spaces in the filenames to dashes.
