GHI FATFS DirEntry problem

[ppetkov]

Hi there,
Some time ago we bought GHI FATFS file system. We use the file system in our data collection system, embedded in a measurement device.
I have the following problem:
Our data collection system creates temporary file after each measurement. The measurement cycle is approx 40 seconds.  When the user start next measurement the system deletes this temporary file.
FAT_DeleteFile() procedure are freeing file clusters and put name[0] = 0xE5; (ENTRY_FREE).
The main problem is that when  we use FAT_OpenFile() procedure  ( in case the file name  not exist in current directory) the file system not use already deleted entries and creates new entry. This way the list of entryes becomes very  long and  our data collection system works very slowly.

Can someone help me?

I am not sure how it works or if this is true but you can split files in several folders. This is much better even if you do not delete any files. It would be faster.
Also, you can make this temporary file, a permanent one with system attribute...
Deleting and creating files can cause fragmentation which will make it slower.
