Given the above script already makes use of pathwouldn't it be better to use path. The latter would be fooled by not-a-lib. Forked it to make it a generator function so that space complexity goes from O n to O 1 link to fork with full implementation here.

Hi, this is an excerpt from a project of mine to make a database of all the MP3 I have, using recursive-readdir. It takes around 40 mins for files. I was wondering how to shorten this time using multiple processes to scan different parts of the file system's portion. Shameless self promotion. I now use smart-fs.

SamMaxwell approach without using lodash. All fine, but how do you create an object than simulates the structure of the actual directory structure?Posted by: admin November 13, Leave a comment. It would probably make most sense if you have control over the folder to create an index.

I recommend using glob to accomplish that task. It supports recursion as well. One more option is require-dir-all combining features from most popular packages. With map you may do some preprocessing, like create objects and pass config values assuming modules below exports constructors :.

One module that I have been using for this exact use case is require-all.

It also allows specifying a file filter and how to derive the keys of the returned hash from the filenames.

All possible values have been mentioned below. It defaults toreadable and writeable. Open file for reading and writing, asking the OS to open it synchronously. See notes for 'rs' about using this with caution.

Open file for reading and writing. The file is created if it does not exist or truncated if it exists. Let us create a js file named main.

Stats class which can be used to check file type. These methods are given in the following table. This method will over-write the file if the file already exists.

If you want to read the file directly using the file name, then you should use another method available. If position is null, data will be read from the current file position.

It is very necessary to find the unnecessary junks and free up them from your hard disk. This brief tutorial describes how to find the largest files and folders in the Linux file system using du and find command. If you want to learn more about these two commands, then head over to the following articles. Some of you would like to display the above result in human readable format.

The above command will show the top directories, which are eating up more disk space. If you feel that some directories are not important, you can simply delete few sub-directories or delete the entire folder to free up some space. To find the largest files in a particular location, just include the path besides the find command:.

Finding biggest files and folders is no big deal. Even a novice administrator can easily find them. If you find this tutorial useful, please share on your social networks and support TecMint.

Keeping track of all these can become a job in itself. I worked at a large insurance company and we were in the midst of a project to take inventory of all the spreadsheets used.

We created a VBA procedure that would take a folder path and spit out all the file names in that folder. Each department was responsible for using this to take inventory of all their files.

Fortunately for me, my department used only a few folders and subfolders for our work otherwise I would have tried to modify the code to loop through all subfolders in a folder. We were using Excel and installing the Power Query add-in was not an option due to IT security lock down. With Power Query this would have been a much less time consuming task and with no coding needed.

From any workbook that you want to create a file inventory in, you can create a From Folder query. Then choose the From File option in the menu and then the From Folder option in the submenu. Add the folder path of the parent folder which you want to query. You can copy and paste this from a windows file explorer address bar or you can use the Browse option to select the folder. Press the Edit button to edit the query. Editing is an optional step if you want more information on the files.

Otherwise you can Load the query without editing. This column can be used to import data from multiple files in multiple folders. To remove the Content column, right click on the column heading and select Remove from the menu. I also like to move the Folder Path column over to the left most column.

You can do this by dragging and dropping the column. Expanding the Attributes column will allow us to see more detailed information about the files. Otherwise we will only see the Folder PathNameExtensionDate accessedDate modified and Date created which may well be all you want to see. You can then filter this table to look at particular folders or file types, or sort on dates to find the most recent version of a file. There is an add-in available for some prior versions of Excel.

Thank you so much Jonh for the clear explanations, I tried it! Is there a way to make this list updated automatically? So that when one of the files from the list will show the latest date?
