我想知道是否有大小限制的数据文件Android应用程序可以使用或大小限制取决于SD卡（或内存）的文件系统？

I wanted to know if there was a size limit to the data files an android app can use or a size limit depending on the SD card (or internal memory) filesystem ?

推荐答案

该文件的大小限制由文件系统决定的。 FAT32，例如，不能处理大于4GB的文件。不幸的是，这是相当有可能，你的microSD卡格式化为FAT32。

The file size limit is determined by the filesystem. FAT32, for instance, cannot handle files larger than 4GB. Unfortunately, it is fairly likely that your microSD card is formatted in FAT32.

为Android 2.2及以上，内部文件系统YAFFS。作者查尔斯·曼宁，国家在这个邮件中的最大文件大小为512 MB。据宣布，的Andr​​oid 2.3将使用EXT4 。

For Android 2.2 and older, the internal file system is YAFFS. The author, Charles Manning, states in this mailing that the maximum file size is 512 MB. It has been announced that Android 2.3 will use ext4.

这也许可以格式化你的SD卡，以这种形式为好，但我还没有尝试过。请记住，你将无法读取Windows或OS X下的内容。

It might be possible to format your SD card to this format as well, but I haven't tried it. Bear in mind that you won't be able to read the contents under Windows or OS X.
