Fat32 how many files in a folder

Each directory must describe the disk location, name and other information where its contents are located.

In the improved file system, the directory information itself is also distributed discontinuously on the disk, so there is no such problem. But in general this is not a problem. In systems with many files, they often create subdirectories for classification.

For example, VSS. In theory, a single FAT32 directory can include up to subdirectories or files. However, if the long file name is used, the actual number of files that can be accommodated is far less than 60, Then, my question is: is it possible to change the size of a folder in number of cluster? Currently I use only 1 cluster and I don't understand how to change it. Is it related to the FAT of the drive?

NOTE: My drive is recognized by Windows when I plug it in, I can access and read every file except those that exceed the limit and I can create new files through the Windows Explorer. It obviously comes from the way I understand file creation and folder creation! A directory in the FAT filesystem is only a special type of file. So use more clusters for this "file" just as you would with any other file. The cluster number of the root directory is stored at offset 0x2c of the FAT32 header and is usually cluster 2.

The entry in the cluster map for cluster 2 contains the value 0x0FFFFFFF end-of-clusters if this is the only cluster for the root directory. You can use two clusters for example cluster 2 and 3 for the root directory if you set cluster 3 in the cluster map as the next cluster for cluster 2 set 0x as value for the entry of cluster 2 in the cluster map.

Now, cluster 3 can either be the last cluster by setting its entry to 0x0FFFFFFF or can point in turn to another cluster, to make the space for the root directory even bigger. The clusters do not need to be subsequent, but it usually has a performance gain on sequential reading that's why defragmenting a volume can largly increase performance. The maximum number of files within a directory of a FAT file system is 65, if all files have short filenames 8.

Short filenames are stored in a single byte entry. Short filenames in 8. The character set is limited. Short filenames that contain lower case letters are additionally stored in a Long File Name entry. If the filename is longer Long File Name , it is spread over multiple byte long entries.

Each entry contains 13 characters of the filename. If the length of the filename is not a multiple of 13, the last entry is padded. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Well, we just watched a 2GB thumb drive frustrate my wife all afternoon, until we a found this thread here, and b verified total items in the root level 2 folders, files. There is a limit on the number of thumbnails, too.

Recently, I hit this limit with my collection of photographs. Now, I have to recreate thumbnails each time in a current directory, because Windows quickly forgets them. On a FAT32 drive, I once got Error 0x It took some time to figure it out… too many files-with-long-names in one folder.

Its entirely possible that you have hit your limit with 15, files due to filename length. Please read the article. Comments violating those rules will be removed.
