USB stick's file system contains of blocks of specific size. Single block size is the minimal space the file takes - even if you place 1 KB file on the exFAT partition with block size 64 KB, whole 64KB block will be reserved.
If I understood your question properly, that's what happened - you have 63 KB free, but can't write anything because there are no fully free blocks left

Reserved? How system use it block? May you can give me utility which erase it without damage for device?

gremlin5: while storing the file, system divides it into chunks and stores each part in separated block (further linked to the file record in FS). The whole block will be used no matter how small the chunk is stored within. Try to create 1 byte file and check its size in properties, you'll see two different values - the real size (1 byte), and the size 'on disk' which will be equal to file system block size.

15432: [[message]saved-xx:yy:zzzz-s:m:h{helloworld.php}] helloworld.php - it is real size?

15432: [[message]saved-xx:yy:zzzz-s:m:h{helloworld.aspx{my message}}] helloworld.aspx - it is real size?

15432: open(my message)->open(helloworld.aspx->my message)?

the question doesn't make much sense. you've written data onto the usb key, you've ran out of space. what did you expect would happen?
if you need to free up space on the key, delete some data.
formatting the usb key will get you all usb key's free space back.

either rephrase the question and/or let us know what exactly the problem is and what's the ultimate goal here.
