O XLSX abre direto no Excel. O CSV (UTF-8) é para outros programas.
Bom saber
Até 2.000 arquivos por verificação. Para pastas maiores, verifique uma subpasta por vez.
Os arquivos são comparados pelo conteúdo, não pelo nome nem pela data: primeiro o tamanho, depois os primeiros e os últimos 64 KB e então o arquivo inteiro.
Arquivos grandes são lidos em partes pequenas, então o uso de memória fica baixo. A velocidade depende principalmente do seu disco.
Arquivos ocultos do sistema (.DS_Store, Thumbs.db, desktop.ini) são ignorados. Arquivos vazios não são comparados.
Perguntas frequentes
Ela apaga os duplicados?
Não. A ferramenta só lê seus arquivos e mostra um relatório. Ela nunca apaga, move, renomeia nem altera nada. Confira o relatório e depois remova você mesmo as cópias de que não precisa, por exemplo no Explorador de Arquivos ou no Finder.
Meus arquivos são enviados?
Não. Tudo funciona no seu navegador, no seu dispositivo. Seus arquivos e os nomes deles não são enviados para lugar nenhum, e a página não usa cookies.
Como ela sabe que dois arquivos são idênticos?
Só podem ser idênticos arquivos com exatamente o mesmo tamanho. Nesses casos, ela compara os primeiros e os últimos 64 KB e depois o conteúdo inteiro com um hash (xxHash128, ou SHA-256 se o seu navegador não permitir WebAssembly). Arquivos com o mesmo conteúdo aparecem juntos mesmo que os nomes ou as datas sejam diferentes.
O que significa “mesmo nome, conteúdo diferente”?
São arquivos com o mesmo nome (sem diferenciar maiúsculas e minúsculas) em lugares diferentes, mas com conteúdo diferente, por exemplo duas versões do mesmo relatório. Eles não são duplicados. Confira qual é a versão atual antes de remover qualquer coisa.
Existe um limite de arquivos?
Sim. Cada verificação inclui até 2.000 arquivos. Se uma pasta tiver mais, nada é verificado e você vê quantos arquivos ela tem. Verifique uma subpasta por vez.
Funciona no celular?
Sim, com os arquivos que você escolher. Escolher uma pasta inteira funciona em computadores nas versões atuais do Chrome, Edge, Firefox e Safari; no celular, depende do navegador.

reproduction, and distribution of the Work otherwise complies with

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 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,
