1# QDirStat Screenshots 2 3Qt-based directory statistics: KDirStat without any KDE -- from the original KDirStat author. 4 5(c) 2015-2021 Stefan Hundhammer <Stefan.Hundhammer@gmx.de> 6 7Target Platforms: Linux, BSD, Unix-like systems 8 9License: GPL V2 10 11 12## QDirStat Main Window 13 14 15 16 17### Different Main Window Layouts 18 19 20_Layout 1 (short): Only the bare minimum of tree columns plus the details panel for the selected item._ 21 22 23_Layout 2 (classic): The classic QDirStat tree columns plus the details panel for the selected item._ 24 25 26_Layout 3 (full): All tree columns including file owner, group and permissions in both "rwxrwxrwx" and octal, 27but no details panel to make room for all the columns._ 28 29 30### Details Panel 31 32 33 34_File selected. Notice the "Package" field: For system files, QDirStat queries 35the package manager (dpkg / rpm / pacman) which package the file belongs to._ 36 37 38 39_Directory selected_ 40 41 42 43_"Files" pseudo directory selected_ 44 45 46 47_Multi-selection_ 48 49 50## Open Directory Dialog 51 52 53 54_Custom "Open Directory" dialog with quick access to the home directory and to 55mounted filesystems. The "Cross Filesystems" check box here is a temporary 56override (just for this program run) of the configuration setting of the same 57name._ 58 59 60## Output During Cleanup Actions 61 62 63 64_Screenshot of output during cleanup actions. Of course this window is purely optional._ 65 66 67## Error Reporting 68 69 70 71_Reporting errors during directory reading. Typically this is because of 72missing permissions, so it may or may not be important to the user. Those 73errors are reported in small panels at the bottom of the directory tree 74widget. The user can leave them open or close them._ 75 76 77 78_Clicking on the "Details..." link opens a separate window that lists all the 79directories that could not be read. This window is non-modal, i.e. the user can 80interact with the main window while it is open. A click on any directory in 81that list locates that directory in the main window, i.e. opens all parent 82branches and scrolls to ensure that directory is visible._ 83 84 85## Mounted Filesystems Window 86 87 88 89_This window (opened from the menu with View -> Show Mounted Filesystems) shows 90the currently mounted filesystems. It does not show system mounts like /dev, 91/proc, /sys, and also no bind mounts, no Btrfs subvolumes and no multiple 92mounts of the same filesystem._ 93 94_The "Reserved" column shows the amount of disk space that is reserved for the 95root user; "Free" is what is available for non-privileged users._ 96 97 98## File Type Statistics 99 100 101 102_Menu View -> File Type Statistics..._ 103 104 105## Locating Files by Type 106 107 108 109_Results after clicking on the "Locate" button in the "File Type Statistics" window._ 110 111 112 113_Locating files with a specific extension. That branch is automatically opened 114in the tree view in the main window, and all matching files in that directory are selected._ 115 116 117## File Age Statistics 118 119 120 121_This window (opened fom the menu with View -> Show File Age Statistics) shows 122the modification time (mtime) of files (not directories) in the selected 123subtree broken down by years; i.e., it shows in what year the files were last 124modified._ 125 126_For each year, it shows the number of files that were last modified in that 127year, the percent of that number relative to all files in that subtree both as 128a percentage bar and as a number, the total size of those files and the percent 129of that total size relative to the total size of that subtree, again as a 130percentage bar and as a number._ 131 132 133 134 135_File age statistics with the months of the current year expanded. It goes into 136finer detail for the months of the current year and the year before, i.e. the 137most recent 13-24 months. The percentages in the months are relative to that 138year, not to the complete subtree._ 139 140_Notice that the months breakdown is always only displayed for the current year 141and the year before, no matter in what year any activity in that subtree 142starts._ 143 144 145 146 147_File age statistics for a subtree where there was no activity at all for the 148last couple of years. Notice how the years up to that first active year are 149also displayed, but greyed out: You can instantly see that the last activity 150was some years ago, even without looking at the year numbers._ 151 152 153## Discovering Files 154 155 156 157_Discovering files of certain categories. Similar to "locating by type" above, 158clicking a file in the list selects it in the tree view in the main window._ 159 160 161## Packages View 162 163 164 165_Packages view: All packages of a Xubuntu 18.04 LTS installation. Notice that 166each directory contains only the files that belong to that package: /usr/bin 167only contains the chromium-browser binary in this view._ 168 169 170 171 172_Packages Summary_ 173 174 175 176 177_Packages view limited to package names starting with "emacs"._ 178 179 180 181 182_Dialog for selecting which packages to display. Use menu "File" -> "Show 183Installed Packages"._ 184 185_To avoid the initial "Choose Directory" dialog, start QDirStat with the "-d" 186or "--dont-ask" command line parameter (or simply click "Cancel" in the "Choose 187Directory" dialog)._ 188 189 190## Unpackaged Files View 191 192 193 194_Unpackaged files view: Some files that obviously belong to Qt 5 on openSUSE 195Tumbleweed, but that are not in the file list of any package. It is still 196possible that some post-uninstall script removes them, but it is also possible 197that they will be left behind when the packages are uninstalled._ 198 199_Notice the greyed-out ignored directories which only contain files that are 200properly packaged._ 201 202 203 204 205_Unpackaged files view: I created my own font for Grub2 which clearly stands out as an unpackaged file._ 206 207 208 209 210_Dialog to start the "unpackaged files" view (Menu "File" -> "Show Unpackaged 211Files"). Some directories are excluded by default because they are expected to 212contain a lot of unpackaged files. You can add more directories or remove 213predefined ones._ 214 215_Since Python tends to leave behind so many unpackaged files, all `*.pyc` files 216are ignored by default. You can add more wildcard patterns to ignore or remove 217the predefined one._ 218 219 220 221## Configuration 222 223 224 225 226_Screenshot of cleanup actions configuration._ 227 228 229 230_Screenshot of MIME category configuration where you can set the treemap colors 231for different file types (MIME types), complete with a real treemap widget as preview._ 232 233 234 235_Screenshot of the exclude rules configuration where you can define rules which 236directories to exclude when reading directory trees._ 237 238 239 240_Screenshot of the general (miscellaneous) configuration options._ 241 242------------------ 243 244 245 246_Context menu of the tree header where you can configure the columns._ 247 248 249----------------- 250 251## File Size Statistics 252 253 254 255 256_File size histogram for a directory_ 257 258 259 260_File size histogram for all files of type .jpg (start from the File Type Statistics window)_ 261 262 263 264_Histogram settings can be tweaked_ 265 266 267 268_Logarithmic scale for the vertical axis if needed_ 269 270 271 272 273_Degenerated histogram if the last percentiles are too far spread out_ 274 275 276 277_Just one percentile less makes all the difference: Scaled down from P100 to P99_ 278 279 280 281 282 283_Numeric percentiles table_ 284 285 286 287 288_Full percentiles table_ 289 290 291 292_Notice the leap from P99 to P100_ 293 294 295 296 297 298_Buckets table (information also available by tooltips in the histogram)_ 299 300 301 302 303_Dedicated help start page for file size statistics_ 304 305 306-------------------- 307 308## Navigation 309 310[Top: QDirStat home page](https://github.com/shundhammer/qdirstat) 311 312[Statistics help page](https://github.com/shundhammer/qdirstat/blob/master/doc/stats/Statistics.md) 313
