Rant: fman criticisms

Here’s my reaction to a reddit thread where a bunch of people were wrong about something. It was about the fman file manager and how the author had spent over 3000 hours making it.

Some people argued that making a general file manager application was “easy” and the author of fman had spent way too much time making such a simple app.

Wrong! Anyone who goes to make a tool as general and versatile as a file manager deserves huge respect.

Doing a UI prototype for two pane file list that lets you browse files is EASY. Making a file manager that actually helps you manage files is HARD.

Let’s see what needs to be considered when we try to COPY A FILE:

  • Cross-platform
  • All filesystems
  • All OS versions
  • Network volumes
  • Filename length limits
  • Case sensitivity
  • Special character encoding
  • Handle and report errors
  • Detailed progress indicator
  • Estimate remaining time
  • Pause/resume
  • Interactive options to overwrite/skip/ duplicates
  • Symlinks
  • Hard links
  • Correctly copy attributes, even when support varies between src/destination
  • Sparse files
  • Special files such as /dev/zero
  • Block size (20 byte file can use 4KB of disk space)
  • Quotas
  • Channels
  • Compression
  • Encryption
  • Optimize for SSD/HDD
  • Optimize for same-volume and cross-volume, cross-device copies
  • Sandboxing

All this must work 100% of the time, on 100% systems, otherwise someone is going to lose their data.

I don’t even know if fman actually takes care of all that, but my point is that I can imagine one could easily spend a good portion of development making JUST THIS and I would consider it a great achievement if it actually worked.
