My sketch has been running for a couple of months quite successfully logging files to the 512MB SD card in my ethernet shield. (All files are currently created in the root directory)
I noticed last night that it was getting errors on creating new files and eventually found that the problem would seem to be due to the number of files "approaching" 512 in the root directory.
As I could not remember how the card had been formatted, I reformatted using SD Formatter. The problem still seems to exist. (Windows Explorer seems to report the file system as "FAT") If I create a folder on the SD card, then I can successfully create more than 512 files in it.

I have a memory card for a Zoom recorder and I want to update the system software on it using the card. It's formatted for Windows luckily enough and says I have to put the update on the root level. I USED to know how to do that. In Big Sur though, I can't find it. Any advice?

The problem I think started with the Media Browser. I recently started a new project and I thought I'd try importing from the card through media browser because I thought it would be a good idea to use premiere to simultaneously import my footage into the project & to my hard drive. The disappointing part is the way media browser didn't allow me to choose a specific folder on my hard drive where I want the footage to go, but instead placed it in the root folder where my project is located.

After the 2nd shoot day, I decided to ignore media browser and instead import the files the way I normally have (Take off card into my hard drive, organize the folders, then import said folders into Premiere). What's happened here (and I have no idea where exactly this issue is coming from) is now after I've dragged the footage into my bins in Premiere, the footage for some reason is being "processed" by Premiere and being duplicated into my root project folder for reasons not entirely clear to me.

and Premiere decides to duplicate all those files I've put into Premiere on the root folder as if those files are non-existent on the hard drive or something. Here is what it looks like (i've removed most of the duplicates already, these are the remaining ones so you know what it looks like) -

Why is this happening and how can I prevent/control this? I'm certain it has something to do with me having tried to use the Media browser at first, since this is the only factor that has changed between this and other projects I've done. I unchecked "ingest" in the media browser while it was duplicating my files but that did nothing. I saw other forum posts that suggests unchecking "allow duplicate media during project import" but that was unchecked from the get-go so I know this wasn't the issue.

In the Media Browser, you can uncheck Ingest if you do not want Premiere to copy imported files to a specified destination. If you do want your imported files to be copied, (for instance, clips imported off of a card are copied to a location) but you want to change the location, you must go to the Project Settings > Ingest Settings and change the Primary Destination dropdown menu.

I think Aaron nailed it. Sounds like you manually copied files AND then had the Ingest setting on when importing. You said you "unchecked ingest in the media browser while it was duplicating my files" but it's too late at that point, it had already begun the whole process. My typical workflow today with memory cards is to just stick the memory card in, turn on the Ingest button in the Ingest Settings window, set a Primary Destination in that same window, and then use the Media Browser to import the clips.

Alternatively, as Jim said, you can manually copy the contents of the memory card to one of your drives and then Import (again using the Media Browser) with the Ingest setting OFF. Two different workflows!

On Android 10 and up, FUSE provides granular access to storage with extra security features. The root of the SD card is a protected space so an app can start from the root and possibly read everything below it, but it cannot be granted write permission starting from the root. This is what happens when I try to add a new folder in Syncthing with the root of an (unencrypted) SD card on Android 10/11 (my Motorola phone previously ran 10 before upgrading to 11):

Samsung likes to layer on its own custom UI on top of a customized version of Android. In the earlier years the changes were significant, but over time Google and other forces convinced Samsung to tone it down.

Officially, Android 9 and earlier did not support apps writing directly to SD cards. Android could use a SD card to extend the main storage, and apps such as media players, file managers, file transfer and so on could read from a SD card, but not arbitrarily write to one.

If Android allowed an app write access to the root of the SD card and all of its subfolders, the app would have the ability to modify files under /storage/[ID]/Android/data/, which could contain access tokens and other private data.

You may try to access a root folder only to find that you can't see it when you're browsing through Explorer. This is because some folders are hidden in Windows by default. See our article How Do I Show Hidden Files and Folders in Windows? if you need help unhiding them.

The root folder is the lowest level directory on your SD card. It's the first folder you see when you open your SD card. You may see folders named DCIM and MISC, or you may see nothing at all if you recently formatted your memory card.

I have a niggling problem with Flashair, which so minor, its hardly worth talking about, but I would like to understand/fix it at some point.. This is more of a Windows question think, but I am sure someone knows the answer.

Does anyone know why I can't see the files in root via a Windows share? Ideally, I would like to save my GCODES to root so that I can easily open them on the printer without selecting the directory...

i think its because you are not adressing the root directory.
The directory you can access is defined in the config parameters.
And as long as i can remember, it can not be the sd-card root Directory.
That means you will always have at least one additional Directory in the sd-card root that will be adressed by a windows mount.

This configuration connects to my wifi network and obtains an address via DHCP. I'm able to browse it as (on MacOS). I can access the root directory without problems.

http is fine (i.e web browser).. my problem is with a SAMBA Windows share. When i open the mount point (\\192.168.1.120] i just see folders and no files.

I don't get anything with SMB/CFS. I'm on a Mac, so things are a bit different. If I try to attach to the Flashair as an SMB server, nothing works. The only thing that works it to mount the volume using **http:://flashair.local** or the IP address. I spent a lot of time assuming it'd work like every other file sharing service I'd worked with, but this one insists on http.

This write up goes through all of the steps requited for the Flashair setup for file sharing and has a good troubleshooting section.
It was written for use with a mk2, but it also works for the mk3.

So my RPI is working great and is running it's OS from the SD card. A lot of the time when I'm programming I don't have an internet connection. I can't make a direct connection to my mac cause it's a Macbook Air and it doesn't have Ethernet. So what I would like to be able to do is the following:

Is there a way to edit the root files from my Mac when the SD is plugged into my Mac?(By saying the root files is mean the files you see when you ssh into the pi with the SD in and enter the command cd /)

Due to the way the SD-card reader is connected in Macbooks, you can't mount the root Filesystem on Partition 2 of the card which is formatted in EXT (no virtual machine or other Programm will be able to access the SD-reader in OSX). The first partition is FAT32, which is automatically mounted by OSX and shows up in Finder.

Note I had to unmount the partition again here like in step 2, it was some how mounted. 12. Run the Virtual Machine and you should see the mounted sdcard partitions (boot and the 32GB partition in my case) now you can edit the files you need.

I have 4GB SD card that I want to put tons of small photos on for a digital photo frame but I cannot copy all the data into the root of the SD card. About half way though the copy it just fails and stops copying.

I remedied this by creating a sub directory and putting everything in that directory and was able to copy all files just fine but it's just not possible to do so in the root. It got me thinking, is this why digital cameras always save their files to sub directories on the memory cards and not the root directory?

I have a project with this type of card reader. There is a testing tool (RS8Test.exe). I can connect to card reader, retrieve card, reject and manipulate with leds. Bu cannot read any data. Smart card is chip based. I found that there are some commands called IC CARD CONTROL. I can activate IC Card, but cannot execute eny command.For example how can I get the root folder in the smart card with Sankyo card reader?

SANKYO ICT3K5 works with magnet stripe and chip based cards. For chip based cards you must activate IC Card functionality at first, then you can send commands to IC Card. RS8Test.exe testing tool receives commands in hex format. For example for File Id = 0x00003F00, Command: 00A40000023F00 you must follow these steps using RS8Test.exe:
