Error: Unable to create <New Folder>...(due to all available directories used).
Error:
Unable to create <New Folder>. Make sure the disk is not full or read-only.
Cause:
Windows uses additional directory entries to store long filenames. All available directories are used up on the root drive. This may be less than the standard DOS allowance of 512 directories.
Solution:
Check the drive for invalid long filenames, and defragment the disk.
1) Check the drive for invalid long filenames (i.e., those which do not meet long filename standards):
a) Open Windows Explorer.
'Explorer' on 'Start' menu
b) In the left pane, select the drive containing the long filenames you want to check.
c) Select the 'File' menu and select 'Properties'. (The '<drive> Properties' dialog box appears, where <drive> is the drive you selected in step 1)b).)
d) Click the 'Tools' tab.
e) Click 'Check Now...' in the 'Error-checking status' group. (The 'ScanDisk <drive>' dialog box appears.)
'Check Now...'
f) Select the drive you want to scan from the 'Select the drive(s) you want to check for errors' list box.
Disk selection
g) Select the desired radio button in the 'Type of test' group.
h) Select the 'Automatically fix errors' check box.
i) Click 'Start'. (When ScanDisk is complete, the 'ScanDisk Results <drive>' dialog box appears.)
j) Click 'Close'. (The 'ScanDisk <drive>' dialog box reappears.)
k) Click 'Close'. (The '<drive> Properties' dialog box reappears.)
l) Click 'Defragment Now...' in the 'Defragmentation status' group. (The 'Disk Defragmenter' dialog box appears.)
m) Click 'Start'.
n) When defragmentation is complete, click 'Yes'. (The '<drive> Properties' dialog box reappears.)
o) Click 'OK'.
2) Rename files or folders in the root directory, using uppercase 8.3-compliant file or folder names.
3) Move some files or folders out of the root directory.
