In the days of applications with no concept of standard file dialogues, running on single-tasking operating systems, for platforms where disc media were sold unformatted, and needed low-level formats, it really was.
Being able to format a floppy disc and continue to do things on OS/2 without applications becoming seriously jerky was also a feature. (-:
CentralPoint PC Tools seems little remembered nowadays. It was quite an extensive toolkit, as I recall. File viewers for various types of database/spreadsheet/wordprocessor files. Disc and file hex editors. Repair utilities. Extended directory change. A uniform look and feel, and a fairly good manual.

Indeed, up to the point that the name was usurped by some unrelated software.
It was very useful even in the later DOS era; it was a standard part of my travelling tech toolkit. It had one of the fastest floppy formatters around, and just about the fastest DOS disk-defragmenter I ever saw, nearly an order of magnitude quicker than Norton's.
The PC Tools backup/restore tool was also superb and extremely fast. It used an extended disk format, squeezing about 1.6 MB onto an HD 3½" floppy, and compressed data on the fly, so many megabytes of software or data could be squeezed onto the minimum number of floppies.
What doomed Central Point software is that it did a licensing deal with Microsoft. Cut-down versions of PC Tools Backup and the separate Central Point Antivirus were bundled with MS-DOS 6. Microsoft promised CP that CP would make money from DOS 6 customers wishing to upgrade to the full versions.
In actual fact, people got by with the freebie versions and CP's sales of standalone products _and_ upgrades both stagnated.
MS tried similar tactics on STAC in the hope of bundling the Stacker disk-compression tool with MS-DOS 6. STAC, wisely, said no.
So Microsoft just stole the code and used it anyway.
It used the money wisely, to diversify the company out of disk compression by acquisition, buying vendors of remote-control software (ReachOut) and enterprise backup (Replica).
Sadly, this was long before ubiquitous Internet connectivity, even by dial-up modem. ReachOut mainly worked by direct-dial modem-to-modem comms -- useful, but expensive, as each machine to be controlled needs a modem, a telephone line and its own phone number.
It wasn't enough and STAC ended up going broke. Central Point Software was bought out by Symantec, like Quarterdeck and Norton and others.
MS-DOS 6 was badly buggy anyway and MS had to release a free update, MS-DOS 6.2. (Note, at this time, product updates, service packs, etc. were extremely rare.)
Then, when it lost the STAC lawsuit, it released another update, MS-DOS 6.21, which simply removed disk compression altogether.
Then MS rewrote the offending code and released MS-DOS 6.22, another free update, replacing the infringing "DoubleSpace" with "DriveSpace" -- basically the same tool but with different compression/decompression routines.
This was the last-ever version of MS-DOS, and thus DOS 6 has the dubious distinction of being the most-patched release in history.
There are details of this on Wikipedia but it's been sanitised by MS PR so it merely mentions patent infringement, rather than the direct code theft involved.

I love how "FORMAT your disk without leaving your spreadsheet" is a feature
