When trying to copy some .nsf files, I receive an error message which says that not enough free space is available, even though files are about 7GB and free space is more than 400GB!

Well I would say make sure that the size of the file you're sending is lower than the available free space on your external hard disk.

And also, some ext. Hard disk has partitions, make sure your pasting in the right partition that has free space.

I hope this helps. Thanks for using FixYa!

Please check how many Mb free disk space you currently have on your transcend device as the description of the pop up message sounds like the default error message from the operating system stating that the file you're trying to transfer is too large to fit on the destination drive. Perhaps try copying and pasting a smaller file first just to make sure that there's nothing wrong with the drive before attempting to transfer such a large file.

firs:
try to format your hard drive, then try again.

if you still cannot do it, do a low level format, using this tool:

if you still cannotdo it, it may be a harware problem. try to copy a big .mkv file like that from another pc, to be sure it isn't your pc's fault, if you can do it, then it's your pc, if you still cannot it's the disk.

in the firs case the troublesooting is quite difficoult but if you post your system configuration i may help.

in the second case if allso a low level format fails, then i don' think we can do something for youo... you should get assistance from the manufacturer....
hope this help,

How many directory deep is the file going that you are trying to save? I believe the maximum NTFS file (location + name) of file length can not exceed 256 characters total.

Example: C:\user\documents\file.exe is OK

But: C:\user\documents\folder\folder\folder\folder\folder\this folder name 230 charicters long\file.exe BAD

If the disc is formatted to FAT32. You will be limited to 4GB files. NTFS is limited to 16 exibytes. Which is huge even by todays standards. 

1. Right click My Computer and select Manage.

2. Open the Device Manager and find your USB drive under the Disk Drives heading.

3. Right click the drive and select Properties.

4. Choose Policies tab and select the "Optimize for performance" option.

Click OK.

6. Open My Computer.

7. Select Format on the flash drive.


Hurrah there is NTFS option available now

8. Choose NTFS in the File System dropdown box.

9. Device Formatting is completed.


Important: To remove a device safely without data loss use a "safely remove hardware" procedure or Eject function from Windows Explorer.

You'll have to remove enough stuff to make room for the new map. I had the same problem which is how I found this site. Turns out, the new map is larger than the one that came on the unit. The 1 GB of available space is pretty much all used when you get the GPS. Just copy all the voices and POIs that you aren't planning on using to your computer in case you change your mind later (you can just download them again for free too). As for the voices, only one works for text-to-speech anyway and that would be Samantha though a male voice is available for download.

You'll need to clear just under 4 MB to make room for the new map, and that's if you haven't added anything. Having the drive/memory on this unit just larger than the map makes it very difficult to get much use out of TomTom's great add-ons.

Simplest solution: back up the data on the drive and repartition it (which will wipe it). Otherwise it sounds like it could be a problem with the file tree or structure of the drive, the configuration files could be corrupt, some program could have stored temporary files in a hidden place that cannot be deleted without making the program delete them, etc. If you are on a mac, spotlight Disk Utility and use it to repartition. If you are on a PC use the search thing from the start menu and find a program called disk management (or something similar to that, you'll know it when you see it.) external drives are annoying. i kick mine into the wall periodically for good measure.

This error message means that there is not enough space in the location you are copying to (internal memory or card). Delete pictures from the location you are copying to, or turn off the camera and insert a new memory card.
