Reasons why the USB flash drive folder cannot be deleted due to garbled characters and Solutions

The USB flash drive folder name is changed to the following situation: Why? Objects or @ are different and cannot be deleted. When deleting a file, the system prompts that the file cannot be deleted and the source file or disk cannot be read. Note that most of the garbled files are very large, even dozens of GB.

The cause of this problem is usually caused by abnormal insertion and removal, which leads to confusion in the file allocation table of the USB flash disk.
Suggestion: run the chkdsk drive letter:/F to check for some errors. If you are prompted to change the folder to a file name, enter y to select YES. In this case, the general problem is solved.
If there are still problems, save some important files as much as possible, format the USB flash drive, or perform low-level formatting, and copy the important files back ~

Other solutions:

1. right-click the problematic USB flash drive icon and choose "attribute" -- "tool" -- click "Start Check" under "error" to solve the problem. if not, try again.

2. Try to rename the file. If you can rename the file. Run cmd to open the task manager, end the explorer process, switch to the CMD command prompt, and enter "del file name" to delete the file. This method is only applicable to files that can be renamed. Close all other unrelated programs before performing the operation.

3. If the system prompts "Access Denied" When renaming a file, run the "chkdsk drive letter:/F" command in cmd running mode to check and fix disk errors.

If a disk error is found, the general error can be fixed. After the fix is completed, you can delete the garbled file.

Note: Sometimes, because the partition where the garbled file is located is the system zone, the system will prompt "another process is calling this volume. Do you want to check this volume the next time you start the system ?" We recommend that you run the chkdsk command in this way, use the Windows installation disk to boot the system, and press "R" to repair the existing system and enter the command prompt status, run the "chkdsk/F" command here. I tested it, and the running effect is much better than that in Windows cmd mode. Run the "fixmbr" command to repair the partition table. It can also fix other system problems.

4. if you still cannot delete the garbled file after the previous step, you can use our most common WinRAR compression tool to delete it. The specific method is to compress the garbled file and select the "delete source file after compression" option. In this way, General garbled files can be deleted.

5. However, if the index block of the file's disk file has been damaged, WinRAR will not be able to solve the problem. At this time, it is necessary to borrow the powerful tool ghost. First, make the partition with garbled file into an image file, then use ghost explorer to browse the image file, find and delete the garbled file, and then restore the image file to the source partition. This method can solve the problem that a large number of garbled file names cannot be deleted.

Garbled USB flash drive file solutions and related data recovery

USB flash drives, MP3, MP4, and SD cards may generate garbled files or folders, which may be caused by incorrect use of mobile devices. For example, when the USB flash drive is still being read or written, the connection to the USB flash drive is suddenly interrupted. Poor contact with the motherboard interface causes a read/write failure on the USB flash drive, which may damage the file system of the Mobile storage device. Otherwise, garbled files and folders may occur on mobile devices such as the USB flash drive, the file and folder size is abnormal, and the format of the USB flash disk or other mobile devices fails. For example, if the file is in raw format, double-click the file to format it, but the format cannot be completed, this basically indicates that the USB flash drive and other mobile devices have been damaged.
Now, the price of the USB flash drive and SD card memory drops, for example, 20-30 yuan can buy a 2G brand-name USB flash drive, but the memory quality cannot be guaranteed, for example, some black merchants will use old chips to stick a brand name and sell it again. In addition, some people will change the corresponding settings on the USB flash drive Board to increase the storage capacity of the USB flash drive, for example, converting 1 GB to 2 GB, but in fact, there is only 1 GB of data. Some USB flash drives come with the data compression function, which makes it difficult to store the data after compression. However, if you store the data directly, there will be a storage capacity, but it cannot be stored any more. At the same time, it will cause a USB flash drive writing exception and data loss. We would like to remind you that you should never purchase such products cheaply.
What should I do if the USB flash drive garbled file, formatting, raw, folder forcedhidden, and USB flash drive capacity display exceptions occur? Many users think they are infected with viruses, repeatedly Use anti-virus software to scan and kill, or use unlock or file crushing tools to repeatedly Delete garbled files, which is useless, because the file systems of mobile devices such as USB flash disks are damaged, such operations have no effect. In addition, some users use foldercure to scan the USB flash disk, and the folder forcedhidden prompt appears, but the repair fails. For those with mild symptoms, there are some remedies here. You can try them one by one.
1. It cannot be formatted on the local machine, or it is required to be formatted repeatedly. Try formatting on another computer.
2. Right-click the drive letter of the mobile disk, and choose "properties"> "Tools"> "" and select "repair file system errors" and "automatically repair damaged sectors". format the drive after successful repair.
3. Some specialized formatting tools can be searched online
4. Based on the USB flash disk chip, re-produce the USB flash disk. You can search for the tool online. However, please note that there is a danger in mass production, which may cause full damage to the USB flash disk and cannot be used. Please be careful.

After formatting is successful, how can I restore files in the USB flash drive? You can use finaldata, recover my files, and other data recovery tools

How to cope with and prevent the security deletion of USB flash drives

The above problems are generally caused by a sudden disconnection of the USB flash drive reading and writing, resulting in data errors. This usually occurs when we plug in the USB flash drive. For example, we often see the following message: "You cannot stop the 'general volatile 'device. Please stop the device later ." So, how can we cope with and prevent the problem that USB flash drives cannot be safely deleted and protect the normal use of our USB flash drives? See the following:

If you want to use a USB flash drive frequently, you may experience the following: "You cannot stop the general-purpose volume device. Please stop the device later ." USB flash drives, MP3 files, mobile hard disks, and other devices are often inserted, and useless prompts are often displayed when you want to safely delete them.

In some cases, you can close the corresponding window and delete it after refresh several times. In some cases, even if you close all running programs, you cannot delete them safely. Some even directly unplug the USB flash drive, which seriously damages the USB flash drive. So how should we deal with this situation? Today we will teach you how to deal with and prevent this problem:

Method 1: Use third-party software
A very small and practical foreign software, only 191kb, called unlocker. This software is very easy to use. It locks the USB connection device to achieve 100% safe deletion of the USB connection.

Method 2: disable the system preview function.

We only need to turn off the system preview function, this problem will not occur again.

The procedure is as follows: click "my computer/tool/Folder Options/General/task/use Windows traditional folder ". Click application and OK.

Method 3: copy and paste operations

First, close open files that exist on mobile devices. In other hard disk partitions for simple operations, such as "copy" and "Paste", and then stop. Terminate the “rundll32.exe process or delete it normally.

The procedure is as follows: Press CTRL + ALT + DEL on the keyboard, and the "Task Manager" window appears. Click the "process" tab, find the “rundll32.exe process in the (if there are multiple rundll32.exe processes, close them all .), Worker Process.
Method 4: uninstall the entire USB driver and reinstall it.

Method 5: enter this code in "start"-"run": regsvr32/u shmedia. dll

There is another way to close the computer. After the flash drive indicator is off, it can be safely pulled out. If the flash drive without the indicator is off, it can be safely pulled out after the computer power indicator is off.

The above methods all have the problem of "unable to stop the general volume device now, please stop the device later". Is there any way to prevent this problem?

First, insert the flash memory to the USB interface. Then, right-click "my computer" in Windows XP and expand "Properties> hardware> Device Manager> disk drive" in sequence ", find "USB flash drive USB device" (different brands of Flash files may have different names), and double-click it to open the "USB flash drive USB device properties" dialog box. Switch to the "Policy" tab, select "optimize for quick deletion", and click "OK" to exit. In the future, ignore the "safely delete Hardware" icon in the system tray, as long as there is no data read/write operation on the flash memory (that is, the flash indicator does not flash ), you can directly unplug the flash memory from the USB interface.
