图片文件,缓存文件等,有必要分很多文件夹吗?
看很多人说,一个文件夹不能超过1000条信息,否则十分浪费资源;
我不太理解;
如果遍历文件,这可能浪费太多资源;
如若给定具体文件路径,不遍历,只读取和修改,这样也十分浪费资源吗?
我的缓存文件夹有10W条缓存HTML; 用复杂算法分很多层目录也难以做到1个文件夹不超过1000条信息. 反而管理比较麻烦.
对缓存文件,只修改,读取,创建. 删除. 具体的路径. 请问这样也会影响性能吗?!
------解决思路----------------------
并不是所有的缓存文件都是会经常用到的，你只要缓存那部分有需要的内容就好了，关于一个文件夹下不要超过多少文件的事情，可能跟磁盘对文件大小划分有关系，我有些不记得了，意思是如果文件够多一个浪费一点 那么一共加起来就会浪费很多空间。
现在的硬件设施我觉得应该不需要考虑这些东西了.
------解决思路----------------------
有些系統，對於一個文件夾內的文件數是有限制的，另外如果文件夾內文件數多，list時會很慢。
------解决思路----------------------
看文件系统。
------解决思路----------------------
同一个文件夹下的文件不能重名（不同文件夹下的文件可以重名）
而可以作为文件名的字符是有限的，因此文件名会变得冗长，可读性下降
操作系统访问文件时，需要先读取目录文件，在目录文件中查找所需文件在硬盘中的位置
显然目录文件较小时，找到文件的时间就较短
