DelinvFile 5.01 supports VISTA, Win-7
thru Win-10 [32 & 64 bit]
The price for the single-user license
for DelinvFile is $31.95 (USD).
Beginning with version 5.01, DelinvFile includes UniCode logic to enable processing of file and folder names
containing characters from other languages and includes "Bulk
Delete", "Multi-select" and a new method for
displaying error messages.
Even though DelinvFile may not have handled your invalid files in the past, give
the new version a try.
Windows allows the creation of file names and folder names
that can not be deleted or renamed via
Windows Explorer. This includes names with invalid characters and
names that are too long.
The current version of DelinvFile includes a function to
scan for invalid names and too-long names.
DelinvFile has been converted to a limited trial.
However, this includes the capability for testing to verify that the program can access and process your problem files and folders.
With this change, registration now includes a 30-day
money-back guarantee to accommodate the situation in which DelinvFile
fails to delete your problem files. DelinvFile
has a function for reporting such a problem when requesting a refund.
Some windows functions allow creation of folder paths such that
the combined path + filename lengths exceed the maximum permitted length.

you can use to delete data files that you have not been able to delete using the
normal Windows Delete function. You could use the phrase 'delete
undeletable files' to describe the program.
Most file delete problems can be
overcome by using a DOS or Command window to:
1. Execute a Delete
command referencing the Short FileName or
2. Execute a Delete
command for the UNC form of the FileName.
However, it is quite difficult to
manually enter a lengthy filename without error. Most of the relatively new
computer users are not comfortable using DOS commands.
