How can I force pcmanfm to refresh its thumbnails. I have a directory of photos in JPG format, (taken with iphone). I have rotated some of these using Ubuntu Image Viewer. When I rotate the image the thumbnail does not update. How can I force it to update? I have tried deleting all thumbnails form ~/.cache/thumbnails and selecting "reload folder" in pcmanfm but no joy. Any suggestions? Where are the thumbnails actually stored? Using pcmanfm 1.2.4 on Ubuntu 16.04.

In pcmanfm, I'd like to open the current folder in wezterm. I've typed "wezterm" in the "Terminal emulator" box in pcmanfm (found at Preferences -> Advanced -> Terminal emulator). If I go to Tools -> Open Current Folder in Terminal, wezterm does start, but not in the correct directory, whereas gnome-terminal does start in the correct directory. I noticed that wezterm isn't listed in this file [terminals.list](https://github.com/lxde/libfm/blob/3289abf583030c664babae64a73d1981afcbe8ed/data/terminals.list) in libfm used by pcmanfm. Maybe wezterm isn't supported by pcmanfm?

I used to use Compiz as my window manager (no desktop environment) on Suse Tumbleweed. When I knew that I can use the LXQT desktop with a window manager of my choice, I installed it and at the first startup I was presented with a list of the installed WM and I chose Compiz. Everything is quite nice, my Compiz configuration was preserved and I will probably use this setup for a long time. BUT When the LXQT session (/usr/bin/lxqt-session, an ELF binary) starts, by default it starts the LXQT file manager like pcmanfm-qt --desktop and I don't want it. How can I prevent /usr/bin/lxqt-session from starting pcmanfm-qt --desktop

When I try to connect to a remote server using PCManFM-Qt Version: 0.16.0: "Go" "Connet to server" "Type SSH" I get the error message: The name: 1.83 was not provided by any service files Does did not solve to install: jmtpfs mtp-tools libmtp-runtime cdtool libcurl3-gnutls libcurl4 libtiff5 umtp-responder go-mtpfs gmtp libid3tag0 lxqt-archiver libfm-tools nautilus. Strangely nautilus connects without any errors. Interestingly, the connections I make in Nautilus show up in PCManFM-Qt

**WHAT I DO:** PCManFM-Qt > Open With ... > Other Applications Choose Application > Installed Applications **WHAT IT DOES:** Displays a blank box. **WHAT I EXPECT:** I expect to see a tree of applications grouped by type. When I use Dolphin it works as expected.

Some examples: - If I plug an external USB drive in, it will get mounted under /media/$USER/ and my file browsers will automatically list the mountpoint under devices. - The same will happen if I manually mount something into a regular folder in my home directory. However, my file browsers will not list the mountpoint if that folder is hidden. - The file browser also won't list mountpoints that are in /tmp, for example. So what are the conditions for a mountpoint to automatically show up in file browsers under devices? Since PCManFM and Nautilus seemingly behave exactly the same, I believe there might be general rules for this? Can I "force" a mountpoint (which is a hidden folder or in /tmp, for example) to show up under devices?

I have configured PCManFM to use "list" view by default; however, it reverts back to "icon" view on its own. This is my configuration: ~/.config/pcmanfm/default/pcmanfm.conf [config] bm_open_method=0 [volume] mount_on_startup=1 mount_removable=1 autorun=1 [ui] always_show_tabs=0 max_tab_chars=32 win_width=636 win_height=1060 splitter_pos=385 media_in_new_tab=0 desktop_folder_new_win=0 change_tab_on_drop=1 close_on_unmount=1 focus_previous=0 side_pane_mode=hidden;places view_mode=list show_hidden=0 sort=name;ascending; toolbar=newtab;navigation;home; show_statusbar=1 pathbar_mode_buttons=0 Shortly thereafter, it turns into this: [config] bm_open_method=0 [volume] mount_on_startup=1 mount_removable=1 autorun=1 [ui] always_show_tabs=0 max_tab_chars=32 win_width=836 win_height=1030 splitter_pos=1 media_in_new_tab=0 desktop_folder_new_win=0 change_tab_on_drop=1 close_on_unmount=1 focus_previous=0 side_pane_mode=places view_mode=icon show_hidden=0 sort=name;ascending; toolbar=newtab;navigation;home; show_statusbar=1 pathbar_mode_buttons=0 View mode gets changed to icon. I even tried setting the file to be immutable :) and ... no dice (I closed all running instances). Is PCManFM respecting the configuration, or is there some configuration file floating around somewhere else?

From the command line, what is the best way to locate the first window where pcmanfm is running, and then give that window focus? pcmanfm does not showcase it's application name on the title bar of the window in which it is running, so you can't focus it using wmctrl -a pcmanfm (which works for me in other applications that do indeed showcase their application's name in the window title bar). This is just one example, but what I'm really looking for is a better method of locating windows that are running a particular command, and then giving that window focus. The title bar method I've been using just isn't always reliable.

Some file managers open very slow on kubuntu, bullseye 11. I had a problem on UDisks2VolumeMonitor, so fixing this, halved the time needed to run. (ps. UDisks2VolumeMonitor --> problem on mraid2 not fixed) fixed by applying some of these: sudo apt-get install appmenu-gtk2-module chmod +x /usr/libexec/gvfs-gphoto2-volume-monitor sudo apt install --reinstall glib2 -y sudo apt install --reinstall gsettings-desktop-schemas fixing XDG_DATA_DIRS paths references: Do you have overlay scrollbars activated? If yes, take a look at this bug report: https://bugs.launchpad.net/ubuntu/+source/xfce4-settings/+bug/1239014 https://gitlab.gnome.org/GNOME/gvfs/-/issues/541 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=950174 So i measured the time these file managers need to run on my system: Dolphin and Krusader less than 10sec.. other more then 30sec. Note: I have 8 usb HDD on self-powered usb hub mounted. So i would like to trace why eg. Nautilus takes 1 while minute to run!!! How i can do this? Do you recommend any other file manager that can be faster (NOT Terminal based)? nemo Current gtk theme is not known to have nemo support (Adwaita), adding some... real 0m34.582s user 0m0.755s sys 0m0.036s after some changes / updates - no error on UDisks2VolumeMonitor Current gtk theme is not known to have nemo support (Adwaita), adding some... real 0m28.351s user 0m0.538s sys 0m0.048s Nautilus error StartServiceByName for rg.gtk.vfs.UDisks2VolumeMonitor: real 1m20.784s user 0m0.878s sys 0m0.072s after some changes / updates - no error on UDisks2VolumeMonitor real 0m55.335s user 0m0.642s sys 0m0.080s thunar error StartServiceByName for rg.gtk.vfs.UDisks2VolumeMonitor: real 0m54.789s user 0m0.465s sys 0m0.076s thunar after some changes / updates - no error on UDisks2VolumeMonitor real 0m29.717s user 0m0.523s sys 0m0.125s pcmanfm WARNING **: 10:19:01.112: XDG_TEMPLATES_DIR is set to invalid path, ignoring it error StartServiceByName for rg.gtk.vfs.UDisks2VolumeMonitor: real 0m52.694s user 0m0.250s sys 0m0.032s after some changes / updates - no error on UDisks2VolumeMonitor WARNING **: 10:19:01.112: XDG_TEMPLATES_DIR is set to invalid path, ignoring it real 0m27.530s user 0m0.410s sys 0m0.094s dolphin QApplication: invalid style override 'GTK+' passed, ignoring it. qt.qpa.xcb: QXcbConnection: XCB error: 5 (BadAtom), sequence: 628, resource id: 0, major code: 20 (GetProperty), minor code: 0 real 0m7.418s user 0m0.833s sys 0m0.091s QApplication: invalid style override 'GTK+' passed, ignoring it. qt.qpa.xcb: QXcbConnection: XCB error: 5 (BadAtom), sequence: 628, resource id: 0, major code: 20 (GetProperty), minor code: 0 real 0m2.385s user 0m0.708s sys 0m0.087s krusader NOT TESTED WITH UDisks2VolumeMonitor error warning default unknown@0 # QApplication: invalid style override 'GTK+' passed, ignoring it real 0m2.268s user 0m0.684s sys 0m0.207s

I have Debian 11 with xfce desktop.After i also installed lxqt desktop when i open the Thunar file manager it doesn't show two of my ntfs partitions in left panel. ‌‌‌But the partitions can be mounted via terminal. And those partitions are not displayed in pcmanfm either. Is there a solution to this problem?

I run Debian 9 with LXQt what is completely fine. However, attached USB-volumes are not getting displayed in the PCManFM-Qt sidebar in category Devices intended for that (see screenshot). Which package is responsible for that? I activated all three necessary options in Preferences -> Volume, but the drives still don't appear in the sidebar. Ironically the taskbar-widget shows the drives and I can easily open them in PCManFM-Qt by clicking on the widget. However they are never displayed in the sidebar while the category Devices remains completely empty. During common workflows that is a bit uncomfortable... ---------- **Screenshot of the issue:** **Screenshot of the working taskbar widget:** PCManFM-Qt correctly" class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Again, clicking on the taskbar widget the device gets opened in PCManFM-Qt without any problems. Only displaying its existence in the sidebar does not work.

Is it possible to get an executable to execute by default? What I mean is this. I have an .sh file, which if I click on twice, it will show me this: If I then click Execute, it does the right thing. Is it possible to get it to Execute without being shown the Execute File dialog box? So simply by double clicking the .sh file, it should do its thing without showing me the Execute File dialog box. I am using Lubuntu/PCManFM if that info is needed.

When I run pcmanfm 'sftp://user@machine', it gives me a 'Operation not supported' error. I think I'm just missing some software for mounting sftp connection into the file system, but I have no idea what it is. Simply running sftp user@machine works as expected, but I'd like to be able to see the file system from pcmanfm, just like you can with KDE's dolphin. I'm fairly certain that this is possible since when I was searching for an answer to this problem, I found some people asking about this, however I didn't find any actual solutions to this problem. Any idea how to resolve it?

I want to tidy my external harddrive. This harddrive is kept in sync with a backup via rsync. When I move/rename (and delete for convinience) files on the disk, it would be nice if those fast actions could also be performed on the backup drive analogical, so I don't have to rsync the corresponding files again. For tidying I like to use a GUI (i.e. pcmanfm). Are there any tools capable of this? //Edited b/c delete makes my point harder to see - I want to avoid rsync deleting renamed/moved files and copying them again to the new location. And I'd like to stick to the tidying process as I'm used to (move/rename and delete things in a file manager with graphical interface).

I recently discovered that a buggy program called pcmanfm was writing 200 MB per second to its run.log file, so I had to find ways to combat that. I discovered what file it was that it was writing to in a laborious manner: du -h for various directories trying to find the offending file. I'm now faced with another similar situation. Something is filling up my hard drive and I have no idea what it is, although I can guess. Is there a way to use lsof to find out what 1 or 2 files are being written to at a high rate? * Can I sort the file list by file size? * Can I sort the file list by writing rate i.e. bytes/second?

I'm making a FUSE filesystem with fusepy and I want to give a special meaning to deletion. I'd like to intercept moves to trash too. For this I would like file managers to use the trash dirs at the root/mount point of my filesystem (.Trash/$uid or .Trash-$uid) rather than the user ones (~/.local/share/Trash). I'm referring to the Freedesktop Trash specification . I've tried 3 file managers: * PCManFM-Qt uses the top-dir trash dir ; * PCManFM tells me the filesystem doesn't support Trash and offers a hard delete ; * Dolphin creates the top-dir trash dir if it doesn't exist but then uses the user one. Can I convince all file managers to use .Trash/$uid / .Trash-$uid?

For example, I know that I can use the command pcmanfm to launch PCManFM and I can also type pcmanfm ~/Desktop to open PCManFM to the desktop folder. However, pcmanfm sftp://[ipaddresshere] gives the error [xcb] Unknown request in queue while dequeuing [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. pcmanfm: ../../src/xcb_io.c:179: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed. Aborted Clearly I'm doing something wrong. So, how can I open PCManFM and connect to a server with one command? I want to place this command in a .desktop file for easy access. Thunar and Nautilus both allow me to do this easily by launching them with the same argument but if possible I would like to be able to do this with PCManFM since I use it elsewhere.

I'm trying to add some custom actions to the PCManFM-Qt contextual menu from this guide on Manjaro wiki. https://wiki.manjaro.org/index.php?title=CUSTOM_ACTIONS_FOR_PCmanFM-Qt Unfortunately none of them are working, I've tested the same thing described there. There's no error log on syslog, dmesg, but this log on the ~/.xsession-errors ** (process:24519): CRITICAL **: fm_file_action_item_launch: assertion 'ctx != NULL' failed So how to fix it ? Thanks ! **I am on Ubuntu 16.04, using PCMandFM-Qt 0.10.0**

After Upgrading my Debian Stable to the Buster version, the alt+up keyboard shortcut (doing cd ..) doesn't work any more. Both Alt+Left (Back) and Alt+Right (Forward) work fine. I'm using Awesome WM and I haven't set Alt+Up as a customized key binding. (PCManFM version 1.3.1)

I use latex in my work a lot. Compiling a latex file generates a lot of intermediate files with .log, .aux extensions. To avoid clutter, I would like to hide these intermediate files. Is there a way to hide files based on their extension?
