Solve the problem that the phone cannot copy 4GB files
|
Reasons why you cannot copy files larger than 4GB to your phone Since we want to cure the disease, we must first understand the root cause. In fact, when you find that your Android phone cannot copy files larger than 4GB into the phone, it must be a problem with the phone's storage space file system. Android is based on the Linux system, and the native supported file systems are ext2fs, ext3fs and FAT32 file systems. The native file systems supported by Windows are FAT16, FAT32 and NTFS. Some mobile phone manufacturers format the phone's storage space to the FAT32 file system so that users can better manage their phones under the Windows system, which causes problems. Friends who have some computer knowledge must know that the FAT32 system uses a 32-bit file allocation table. Although it breaks through the FAT16 limit of only 2GB for each partition, the FAT32 file system limits the size of a single file in the partition to 4GB. We cannot create files larger than 4GB on the storage space of the FAT32 file system, so we cannot copy large-capacity audio and video files into a phone formatted in FAT32 format. In this era of "big data", GB-level files can be seen everywhere. It is obvious that formatting the mobile phone storage space into the FAT32 file system is not keeping up with the times. Solution 1: Use NTFS file system memory card Since the internal storage space cannot be used, we can use the Micro SD memory card. It seems to be a good idea to format the memory card into the NTFS file system that can support a single file larger than 4GB, but a new problem arises. The Android operating system does not natively support the NTFS file system. However, someone is unwilling to give up and developed an application called Paragon NTFS. By installing the Paragon NTFS application, the Micro SD memory card formatted with the NTFS file system can be mounted on the Android operating system, so the problem is solved. Solution 2: Use exFAT file system memory card In addition, the author also found that some Android smartphones can support the exFAT file system. exFAT is a file system suitable for flash memory introduced in Windows Embeded 5.0 and above systems. It was launched to solve the problem that FAT32 and other systems do not support 4G and larger files. However, since it is necessary to pay a certain licensing fee to Microsoft to provide support for the exFAT file system, not all Android smartphones can support Micro SD memory cards formatted with the exFAT file system. The author selected some popular models for exFAT format memory card compatibility test: From the above table, we can see that not all Android smartphones can support memory cards with the exFAT file system, so if your phone cannot use memory cards with the exFAT file system, please try the first method above. When purchasing Android smartphones in the future, you should also take the support for the exFAT file system into consideration. Finally, I want to say that when mobile phone manufacturers install 1080P screens on mobile phones, when mobile phone manufacturers launch mobile phones with 4K video decoding capabilities, and when mobile phone manufacturers launch large-capacity storage mobile phones on the market, dear! Please think about whether these mobile phones on sale can support the copying of large-capacity files, and whether they are really well considered for audio and video entertainment enthusiasts. I hope we will hear affirmative answers in the future.As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
