我试图在一个包含192个jpg文件的目录上使用jobb工具，总计约70mb。当我运行jobb -d C:/sdk/tools/dir/data -k 123456 -o com.nick.app.obb -pn com.nick.app -pv 1命令时，它会生成以下日志：

对此有什么建议吗？
最佳答案
根本原因分析：
de.waldheinz.fs.fat.DirectoryFullException: directory is full
当
Fat16RootDirectory becomes full或ClusterChainDirectory grows beyond it's ClusterChainDirectory's maximum size(512 MB)时发生此错误。从何处发生异常？：DirectoryFullException.java
DirectoryFullException(int currentCapacity, int requestedCapacity) {
this("directory is full", currentCapacity, requestedCapacity);
}
对于这个问题，我更喜欢一个解决方案和一些建议。希望对你有帮助。
解决方案1：
在windows上：如果你有一个“data”文件夹，其中丢失了图片，并将其复制到android sdk tools目录
data/1.jpg
data/2.jpg
data/3.jpg
data/...
data/5000.jpg
你用
console>>>jobb -d C:/sdk/tools/dir/data -k 123456 -o com.nick.app.obb -pn com.nick.app -pv 1
你会得到提到的错误。尝试添加一个目录层次结构并将“数据”目录设置为子文件夹
root/data/1.jpg
root/data/2.jpg
root/data/3.jpg
root/data/...
root/data/5000.jpg
使用
console>>>jobb -d C:/sdk/tools/dir/root/data -k 123456 -o com.nick.app.obb -pn com.nick.app -pv 1
你必须记住，如果你想以后从obb中阅读，图片现在在一个子文件夹中。
资源链接：
Using jobb tool in Android
What causes jobb tool to throw FAT Full IOException?
Suggestion-1:
要检查
sector/cluster/FAT大小，请运行"jobb -v -dump [obb]"。它将打印一堆信息，包括"Sectors per cluster"和"Sectors per FAT"。在我以前的obb中，这些值分别是8和150。8不是150的因子，所以我可能碰到了上面描述的内核错误。
您需要确保使用更新的
jobb.jar和fat32lib.jar来解决该问题。根据google驱动器上当前版本的库，我现在得到每个集群8个扇区，每个fat 184个扇区。我还没有证实这是否修复了我之前看到的数据损坏问题。我会做更多的测试和报告回来。
建议2：
Hacking can solve the issue。但却带走了更多的记忆：
这个问题确实开始变得非常无聊。今天我想出了一个解决办法，这很荒谬，但看起来在.obb中添加额外的数据似乎可以解决这个问题（至少对我来说是这样）。准确地说，我原来的.obb文件大小是110MB，现在是220MB，应用程序读取数据时没有损坏。这是迄今为止，我对一个应用程序做过的最肮脏的黑客攻击，我对此并不感到自豪，但嘿，至少现在正在工作。：p页
建议3：
2015年10月19日，他们发布了一个更新版本：android-sdk-fat32lib
这个版本是为了解决android sdk发布的jobb工具的一个问题，因为
(Android SDK 23)无法生成大于512m的obb文件。更新：
您将在以下部分获得原始版本和修改版本的源代码：
原始版本可在https://github.com/waldheinz/fat32-lib/
修改版本可在
https://android.googlesource.com/platform/external/fat32lib/
要从源代码生成jar文件，可以按照教程进行操作：
