El XLSX se abre directamente en Excel. El CSV (UTF-8) es para otros programas.
Para tener en cuenta
Hasta 2,000 archivos por análisis. Para carpetas más grandes, analiza una subcarpeta a la vez.
Los archivos se comparan por contenido, no por nombre ni fecha: primero el tamaño, luego los primeros y últimos 64 KB y después el archivo completo.
Los archivos grandes se leen por partes pequeñas, así que el uso de memoria se mantiene bajo. La velocidad depende sobre todo de tu disco.
Se omiten los archivos ocultos del sistema (.DS_Store, Thumbs.db, desktop.ini). Los archivos vacíos no se comparan.
Preguntas frecuentes
¿Borra los duplicados?
No. La herramienta solo lee tus archivos y muestra un informe. Nunca borra, mueve, renombra ni modifica nada. Revisa el informe y luego elimina tú mismo las copias que no necesites, por ejemplo en el Explorador de archivos o en Finder.
¿Se suben mis archivos?
No. Todo funciona en tu navegador, en tu dispositivo. Tus archivos y sus nombres no se envían a ningún lado, y la página no usa cookies.
¿Cómo sabe que dos archivos son idénticos?
Solo pueden ser idénticos los archivos que tienen exactamente el mismo tamaño. En esos casos compara los primeros y últimos 64 KB y luego todo el contenido con un hash (xxHash128, o SHA-256 si tu navegador no permite WebAssembly). Los archivos con el mismo contenido aparecen juntos aunque tengan nombres o fechas distintos.
¿Qué significa “mismo nombre, distinto contenido”?
Son archivos con el mismo nombre (sin distinguir mayúsculas y minúsculas) en distintos lugares, pero con contenido diferente, por ejemplo dos versiones del mismo informe. No son duplicados. Revisa cuál es la versión vigente antes de eliminar algo.
¿Hay un límite de archivos?
Sí. Cada análisis revisa hasta 2,000 archivos. Si una carpeta tiene más, no se analiza nada y ves cuántos archivos tiene. Analiza una subcarpeta a la vez.
¿Funciona en el celular?
Sí, con los archivos que elijas. Elegir una carpeta completa funciona en computadoras con las versiones actuales de Chrome, Edge, Firefox y Safari; en celulares depende del navegador.

notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and

reproduction, and distribution of the Work otherwise complies with

any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

Bundled file: vendor/Montserrat-Bold.ttf
------------------------------------------------------------------------
Copyright 2024 The Montserrat.Git Project Authors (https://github.com/JulietaUla/Montserrat.git)
This Font Software is licensed under the SIL Open Font License, Version 1.1.
This license is copied below, and is also available with a FAQ at:
https://openfontlicense.org
-----------------------------------------------------------
SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
-----------------------------------------------------------
PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this license and clearly marked as such. This may
include source files, build scripts and documentation.
"Reserved Font Name" refers to any names specified as such after the
copyright statement(s).
"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).
"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.
"Author" refers to any designer, engineer, programmer, technical
writer or other person who contributed to the Font Software.
PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining
a copy of the Font Software, to use, study, copy, merge, embed, modify,
redistribute, and sell modified and unmodified copies of the Font
Software, subject to the following conditions:
1) Neither the Font Software nor any of its individual components,
in Original or Modified Versions, may be sold by itself.
2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy
contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or
in the appropriate machine-readable metadata fields within text or
binary files as long as those fields can be easily viewed by the user.
3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.
4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any
Modified Version, except to acknowledge the contribution(s) of the
Copyright Holder(s) and the Author(s) or with their explicit written
permission.
5) The Font Software, modified or unmodified, in part or in whole,
must be distributed entirely under this license, and must not be
distributed under any other license. The requirement for fonts to
remain under this license does not apply to any document created
using the Font Software.
TERMINATION
This license becomes null and void if any of the above conditions are
not met.
DISCLAIMER
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM
OTHER DEALINGS IN THE FONT SOFTWARE.
