Pros
Pro Can be used in terminal
Which makes for a good choice of file explorer for those that use machines without a GUI.
Pro Minimalist and efficient
There is no need for icons of files if headings are used. Previews of text documents and a simple design creates and efficient workflow.
Pro Vim-like bindings
Ranger has Vim-like keybindings which help a lot in increasing efficiency and speed up the workflow.
Pro Extensible, scriptable (with python)
Ranger allows the use of various scripts for calling on individual or multiple files, for file previews, or for other operations.
In commands.py the "my_edit"-function can be extended to do whatever in python can be done. Target files can be the file under the cursor (self.fm.thisfile.path), the files marked/selected in the current tab (self.fm.thistab.get_selection() ) and the files in the copy-buffer (add/remove: ya, yr) (respectively the delete-buffer: add/remove da/dr) (both: self.fm.copy_buffer).
The most appropriate list of files can be found out automatically, like so:
if self.fm.copy_buffer:
for file in self.fm.copy_buffer:
...
elif self.fm.thistab.get_selection():
for file in self.fm.thistab.get_selection():
...
else:
file = self.fm.thisfile.path
...
Pro File preview
Unlike other terminal file managers, Ranger can preview many files, including text files, archives, etc, but also pdf files, pictures and videos.
Pro Bookmark system
Makes it easy to jump to any specific folder locations you work with.
Pro Easily used with SSH
Pro Image preview support
Ranger can use w3m to preview images in terminal through framebuffer.
Pro Fast and responsive
This software is super fast and responsive in navigation.
Pro Treeview and listview (equal viewports) possible
Supports any number of viewports on folders side by side.
Pro PDF preview
This may fall under "File preview", but it is a very powerful feature for PDF files in particular.
Pro Purposeful layout choices
Polo wants people to get the file manager they want, but it's not awash with granular layout options that take ages to understand. First select whether you want one, two, or four panes, and then select a format for each pane of either List, Icon, Tiled, or Media. That's it, you're done.
Pro Installs smoothly on Debian, Redhat and Arch based distributions
File managers in Linux have a nasty propensity for being closely tied to the distribution family from which they arose. Using Polo allows you to have an identical file management experience when shifting between machines from different branches of the Linux tree.
Pro Device management
Quickly mount and unmount devices from the sidebar, including support for locking and unlocking LUKS encrypted devices.
Pro Youtube-dl integration
Just paste a YouTube URL into a folder and Polo will download the best quality format of it and save it in that folder.
Pro Archive browsing and creation
Browse archive files as those they were just another folder, dragging and dropping files in and out of them at will while the backend uses the appropriate tools to manage the archive file itself. Archive creation includes a rich assortment of controls over compression formats and structure.
Pro Image file actions
Rotate, resize, optimize, convert formats, save for the web and many other handy features all right in the context menu.
Pro ISO file tools
Mount ISO files to loop devices with just two clicks, or spin them up as a QEMU KVM instance, and for portability there's also an option to write them to USB flash drives using a GUI dialog.
Pro Advanced PDF file controls
Perform Merge and Split operations on PDF files without needing another file handler all from the context menu. Rotate and Password Protection settings are also expressed there.
Pro Cloud storage support
Includes its own rclone macros for adding cloud storage access to the list of browsable locations that just works, a welcome relief in the sea of hacks which provide those features elsewhere in Linux. Currently supported: Dropbox, Google Drive, Microsoft OneDrive, Amazon Cloud Drive / Amazon S3, Openstack Swift (Rackspace Cloud Files, Memset Memstore, OVH), Hubic, Backblaze B2, Yandex Disk
Pro Views
Supports up to four panes, plus a tree-style side panel and tabs.
Pro Terminal emulation
Built-in terminal pop-up.
Pro Launchpad PPA available
Debian-based distributions can leverage the apt package management system to keep Polo updated by adding the approved PPA to their apt sources, simplifying installation as well.
Pro Permissions management
Features a file properties side panel to easily assess and modify permissions.
Cons
Con Bloated
Written in a scripted language. Enabling file previews makes it even slower.
Con Depends heavily on third party utilities
Con Difficult learning curve for people who are not used to Vim
Since it uses many of vim's keybindings, it may be hard for someone who does not use vim or does not know how to use vim to learn how to work with this file manager.
Con No way to calculate folder size
Con Needs heavy configuration to setup
Con No built-in ability to navigate FTP/SSH
Most other GUI-based file managers provide easy bookmarking and browsing of multiple FTP & SSH locations using either keys or keychain stored user credentials. Ranger doesn't have this.
Con A great idea but not GUI friendly
May be difficult to get past the fact that it asked for commands dd and cc and the likes to cut and or paste. Arch-Linux normally prides itself on not over-complicating things. Too bad ... a great idea with the 3 Smart Columns, but why would anyone prefer to need to learn 30 commands in order to cut and paste or copy a file or folder, or to see/change permissions.
Con Freemium model
Many of the best features mentioned as pros are only available after a one-time donation of USD$10 or more. Until then you just have a fast, good-looking and otherwise forgettable file manager.
Con No drag and drop
You can't drag from one view to another.
Con Load loop
Slow opening with annoying 'load loop' dialog.
Con Lengthy beta cycle
Polo has been in the beta stage of development for longer than hoped for, and while mostly stable, isn't yet ready to be promoted as a rock-solid replacement for file managers such as Dolphin and Nautilus.
