Sigma File Manager review: open source and cross platform

Sigma File Manager was just released. The open source file manager is available for Windows, Mac and Linux devices, and while its version is 1.0.0, it should be considered alpha according to the author.

It is an Electron app, and if you don't like these apps, because many are bloated and too large for what they do, then you may want to check out alternatives such as File Commander. Sigma File Managed does have several interesting features that may persuade you to give it a try, even though it is Electron-based.

The program has a size of 120 Megabytes for Windows and you may get a SmartScreen prompt when you download it because it is new and unknown to SmartScreen.

The startpage looks quite different, as it features a photo at the top and below that links to system directories and drives.  The photo can be turned off in the options, and you may pin your own selection of items.

The app did not detect drives on the Windows 10 version 21H1 system I tested it on, but threw an error message on start instead. The default test account is a basic user account, but even running it with elevated rights did not display the drives. A test on a Surface Go system, with Windows 10 version 21H1 as well, was successful. The drives were shown and all features worked as intended.

A click or tap on a folder or drive displays the files and folders under the selected structure, but you may also use the address bar or breadcrumb navigation to switch directory levels.

Strings that you type are auto-completed, e.g. to quickly open a new directory without typing it fully.

The default layout displays folders and then the files, each with dates and either the items they contain or their size.

Details about the selection are displayed in a sidebar on the right. Certain file types are previewed, e.g. images, and you get other properties about the selection, e.g. the size of a directory. Sigma File Manager has a built-in archiver to compress or extract common archive formats.

You may switch to grid layout if you prefer it, and use controls at the top to filter by what you type, regardless of order and spelling mistakes.

The developer states that the program searches through 100 Gigabytes of data in about 2 seconds.

The item filter is useful as well, as it enables you to filter by file type, size, year, or other parameters.

Sigma File Manager supports tabs and workspaces to improve the manageability of content. You may use the shortcuts Alt-[0-9] to switch between tabs quickly, or click a button to do so.

Workspaces are useful to customize access to data further, e.g. when working on multiple projects at the same time or for different tasks. Workstations maintain their own sets of tabs and actions; actions are quite interesting, as you may define actions to open websites or programs, set default directories and more.

Another feature that you don't find in many file managers is the ability to download files using the file manager. Drag & drop links onto the app to stat the download. The app supports video streams, but only one site, operated by Google, is supported at the time. Support for more sites is on the way according to the developer.

Drag & drop functionality works with local files and folders as well. You may use the feature to copy or move files quickly.

The app has a number of other useful features. File Protection is one, it allows you to protect files against accidental renames, moves, deletions or modifications.

Closing Words

Sigma File Manager is a well thought out app that has several interesting features. It should be considered alpha at this point, the performance on the Surface Go device was not good, but the device is not powerful either, so that certainly plays a role.

The developer plans to add more features with every release of the app, and it will be interesting to see how it evolves. It seems unlikely that users who dislike Electron will be convinced to give it a try though.

Now You: what is your preferred file manage?

    I love auto-playing videos. It saves me a thousand clicks a day.

      And probably costs your a good amount of data, if you don’t have a good plan. Better would be an opt-in than opt-out.

    I hate auto-playing videos. Never click on them. Never watch them. Just one more manic marketing/advertising ploy that is rampant on the internet, to grab your attention intrusively, greedily, and glaringly obnoxiously. Second worst is those stupid timed pop-ups to get you to sign-up for something. No wonder so many people have screwed up attention spans.

    Telegram is introducing Telepathic Videos, they play in your head and can’t be stopped unless you turn off the app, put the device in your freezer (no signal, batteries die quickly) then go outside into reality. Scary proposition but definitely worth trying.

    Unfortunately there’s still no way to stop an autoplaying video once you’ve started it. So you get to choose; either don’t watch it at all… or watch it looping for all eternity.

    More great UI design from your friendly neighbourhood Telegram devs. The people who brought you “no scrollbars on OSX” and “allowing other people to remotely delete data on your devices”

      Not true, at least not on my Telegram desktop PC setup; I started playing a video that I couldn’t find a way to stop playing in a loop over and over again, which led me to find this article.

      I followed the article’s instructions and toggled off the autoplay for videos and GIFs for all three categories, Private, Group and Channel, and once I did that and saved the settings the previously perma-looping video stopped and the UI was replaced with a blank window and a ‘Play’ symbol.

    Hmm, on the website it states: “There’s no shady stuff as 100% of the website is open source.” No, it required some scripts for the basic website to even load… It can be classified as untrustworthy and poor quality design.

    Martin, where do you predict this post will be sent today, will it reach the correct thread or be redirected to some random thread on AI, Social media fads, or be tapped onto a long debate on browser bug comments. Your visitor comments database is kaput! :-/

      Martin, the [#comment-4572556] post did weirdly redirect to: [https://www.ghacks.net/2023/08/14/is-beeper-safe/] and now it seems to be back in the correct “.sexy” thread. Maybe it’s a homing pigeon.

      However, the last (currently) visible response to the “Wi-Fi” thread, instead nested in the “beeper” one. It also looks like the other posts people made in that “wireless” thread, migrated south and flew into others threads. It’s like Russian roulette with replies trying to reach the right destination nowadays – around here.

    privacy.sexy may not be a great resource – for example, one of the scripts in the ‘configure programs’ scripts for Firefox enables ‘privacy.firstparty.isolate’ – FPI is obsolete and has been replaced with dFPI which can be enabled in ‘preferences > privacy & security > enhanced tracking protection’ by selecting the ‘strict’ option

    another script disables WebRTC to prevent IP leakage (VPN, etc.) – this is apparently no longer necessary (see ‘[SECTION 2000]’ of the arkenfox js)

    I have reached out to Martin personally and to his credit he replied very quickly. He has informed me that they are aware of the problems and are attempting to fix it.

    Martin is no longer involved in the technical management of the site so I imagine if we want to ask someone then our comments would perhaps be better directed towards Softonic.

    PORTMASTER

    I stopped using this because it doesn’t prevent DNSAPI.dll from allowing the PC to make sneaky connections to Micro$oft. I put my Acrylic M$ blocklist into the Custom Filter option but it Micro$oft URLs would still bypass it (and of course the regular Hosts file).

    Back to Acryllic and Tinywall! Most people don’t care about M$ spying on them, but some of us still do. So even though Portmaster ‘owns’ port 52, it still let’s DNSAPI.dll over-ride one’s privacy options.

    Oh, the irony!

    Disheartening news for me, as I really rely on SUMO for the updates for the last 5 years or so.

    Others I tried–even ones with big brand names–are junks compared to how extensive and useful SUMO’s features are.

    Anyone can recommend a list of 2-3 softwares at par with SUMO? Thank you.

    I purchased a lifetime license of Sumo in 2018 and I was very satisfied with this program.
    There are not many alternatives and those that exist are not as effective.
    See alternatives here : https://alternativeto.net/software/sumo/
    Secunia was also abandoned some time ago.

    I haven’t used any of their products, but I have a bookmark to the site. Chances are good that Major Geeks will archive all the products, a sort of repository for KC Software.

    Sad news indeed. Been using SUMo for a long time.

    As mentioned, an article about alternatives would be welcome.

    Kaspersky will be happy, they’ve been flagging SUMo as “incompatible software” for years, only because it competes with their KIS’s Software Updater junk. No “Ignore” option for their blatant anti-competitive deceit. Of course.

    What’s with all the old unrelated posts crap? @Martin Brinkmann can you please get rid of that time-wasting nonsense, it makes reading and finding genuine comments a serious PITA!

    Very sad news indeed.

    Before SUMo I was using WebMon, a free software which was monitoring web sites for changes and it was very good, but the software was discontinued and stopped working correctly on https sites for which it was not programmed.

    I think that I will return to this kind of software, I am actually trying the free version of “WebSite-Watcher” which is a shareware, and I’ll try to find some other softwares of this kind.

    Actually this is the only kind of software which would be able to “find” new versions for installed softwares but also for portable softwares.

      >Before SUMo I was using WebMon, a free software which was monitoring web sites for changes and it was very good, but the software was discontinued and stopped working correctly on https sites for which it was not programmed.

      There is modern recreation of WebMon, which support https (and a number of other additional features), called WebChangeMonitor:
      https://sourceforge.net/projects/webchangemon/

      Also, in addition, I can recommend a somewhat similar program Ketarin (HP: ketarin org) – it has not been updated for quite a while (but not as long as WebMon), but is fully functional. Its plus is that it can also download files (in fact, this is its main function – after detecting changes, like WebMon, download a given updated file). Everything must be configured manually, as in WebMon, so as an alternative to SUMO may not be for everyone, but for someone who used WebMon – very much so.

    I prefer alert of new versions rather than manual updating so the installer/portable app can be scanned via VirusTotal before installation. SUMO gave the alert and a right-click option to open the app folder, which was all I ever used.

    Wingetui is an alternative to SUMO but it is not as comprehensive. It misses seeing some of my software. The article above mentions ‘several good alternatives’. Alternativeto lists a lot but lacks https://alternativeto.net/software/sumo/ but does not give thorough reviews.

    Has anyone experience with the free version of IObit Software Updater?

    (Yes I know that IO does everything to overwhelm your PC, and Malwarebytes is still very angry/aggressive towards IO, but they have some very good (free) programs, and you can rely on that they are not one-man-projects).

      I have tried it. It sneaky installs a brunch of other programs which causes an almost uncontrollable chaos. So not advisable (through the updater program itself seems to be very functional).

    Ketarin (https://ketarin.org/index.php) looks interesting and I just downloaded this morning to start tinkering. It takes a bit of work to configure each piece of software. When first run it downloads the software on each link. Subsequently, it downloads new versions. It is portable, so you could load it plus downloads onto a USB stick and use it to install the same apps on different (compatible) computers.

    The new version (10) of uCheck now allows mentioning custom locations.

    I asked their support if this option is reserved for the paid version.

      Their answer:
      “Hi,
      Thanks for your message.
      Yes it should be scanned in the Free version as well. However, it’s just client capability for now.
      We are in the process of adding portable links in our database right now, so it’s normal if there’s very few (or not) software found in these locations.”

    Sad, SUMP was by far the best program for finding the latest updates, even for obscure apps. Would like to see them open source their entire line up, so someone else can take up the torch! Would be sad to see it go down to no good end! Thank you SUMO for all the good work you’ve done for the public good!

    Just used SUMo, Patch My PC, and winget.
    SUMo found 9 major, and 16 minor updates
    Patch My PC found 8 updates
    winget found 11

    False negatives: determines there was no update, when in fact there is an update

    False positive: determines there is an update, when in fact there is no update

    winget has a lot of issues.
    False negative: it didn’t list updates for Chrome, and Thunderbird
    Also had one false positive, i.e., there was an update when in fact it doesn’t exist.

    The Microsoft C++ Redistributable updates leave old ones behind, so winget reports then out of date.

    There was a false positive for Patch My PC.

    SUMo is the most comprehensive and accurate of the three products tested.
    I did not find any false positives or false negatives.

    I originally used Secunia to check for updates until is was discontinued.

    Just ran SUMo, Patch My PC, and winget.

    Both SUMo and Patch My PC found an update for LibreOffice, but the winget upgrade command missed it.

    The winget list command shows LibreOffice, but no update.
